Section 1: Introduction
1.1 Background
For many years licensing authorities (including navigation authorities1 ), and the hire boat trade, have been applying standards and regulating hire boats through initiatives such as the Boat Safety Scheme (BSS) and the British Marine Federation (BMF) Hire Boat Handover Audit Service.
The accident to the day-hire boat Breakaway V in July 2003 in which the boat capsized leading to the drowning of one of the occupants, was investigated by the Marine Accident Investigation Branch (MAIB). Their report (reference 4) recommended:
•Development of a national code of safe practice for boats let for hire on inland waterways and co-ordination of the licensing regimes of local authorities and navigation authorities, including the empowerment of the latter to licence where required.
•A review of the international standard on boat stability.
•Encouraging boat builders to obtain independent assurance of compliance with the Recreational Craft Directive
The Maritime and Coastguard Agency (MCA) initiated discussion of the recommendations with stakeholders from across the hire-boating industry. It was decided that it would be appropriate for a non-statutory code to be produced jointly by the MCA, the Association of Inland Navigation Authorities (AINA), and the BMF which would set down best practice and be suitable as a basis for licensing by local or navigation authorities.
The approach adopted in this Code is based on the foreseeable risks of hire boating activity and recognises the responsibilities that navigation authorities, hire operators and hirers have in ensuring adequate levels of safety. The risk control measures are considered to be reasonably practicable given the level of risk, and are consistent with established principles of risk management (see section 1.3).
1.2 Scope
The Hire Boat Code is published in two parts:
Part 1, the present document, deals with power-driven boats. These include:
Refer to the definitions given above for further details.
1 Note that throughout this Code references to navigation authorities is taken to include Harbour Authorities in whose area hire craft operate.
2 Refer to ‘Managing Personal Watercraft’. Personal Watercraft Partnership 2004
This issue of Part 1 deals specifically with technical and operational issues pending agreement of the arrangements for certification and verification of standards by licensing authorities. When these arrangements have been agreed a full issue of this Code will be issued for consultation (section 1.4)
Part 2 will deal with unpowered craft.
1.3 Principles for determining standards.
The National Water Safety Forum have published a set of ‘Principles for Water Safety’ (reference 5) which are intended to help ensure that safety across the water sector is applied in a way that is consistent, proportionate, and fully recognises the broader societal benefits of water-related activity. They have been applied in the production of this Code.
Account has also been taken of the available data on accidents and incidents in the sector.
1.4 Consultation.
The drafting of this code was carried out by representatives of the BMF, MCA and AINA. Drafts were circulated to members of the BMF working group, and the AINA Safety Issues Group 3. Following amendment, a revised draft was circulated to all BMF members, AINA members, and the organisations represented on the initial working group set up by the MCA when the project was started, this latter group being considered to represent the full range of stakeholders.
Lastly, a final draft was placed on the BMF, AINA and MCA websites for twelve weeks public consultation prior to finalising the first issue of the technical and operational aspects of the Code. Principal stakeholders were notified by email. A full list of consultees is given in appendix 3.
The responses to comments raised during consultation were posted on the BMF, AINA and MCA websites.
Any proposals for revisions after first issue will also be subject to appropriate consultation, see section 9.
1.5 Implementation
Full implementation of the code requires a number of activities to be completed. These include:
a) Achieving required technical standards on existing craft,
b) Having sufficient trained resources to carry out stability tests,
c) Introducing revised schemes of certification (e.g. Boat Safety Scheme)
d) Training sufficient numbers of examiners
e) Review and revision by licensing authorities of their licensing arrangements and conditions for hire craft.
3Note the AINA Safety Issues Group also acts as the Inland Waters Advisory Group of the National Water Safety Forum.
The scope and programme for implementing items c), d) and e) above are under consideration by the sponsoring organisations.
This issue of the Code will be released for consultation in Spring 2008. It is considered that this will give hire operators in particular, sufficient time to comment and make the necessary arrangements for achieving the required standards.
Subject to agreeing their approach to the licensing and enforcement aspects of the Code (to be published in the full issue of the Code), it is anticipated that licensing authorities will commence seeking self-certification by hire operators of compliance with the Code from Spring 2009 with the full arrangements in place during 2011. A detailed implementation plan will be published on the BMF, AINA and MCA websites 4. These organisations will oversee implementation and amend the programme accordingly as well as acting to overcome any difficulties that may arise (Review arrangements are discussed in section 8).

Section 2: Responsibilities
The principal parties involved in the hire of a vessel all have responsibilities for safety, (reference 5). The hire operator has a duty to the hirer to provide a vessel that is safe to operate and live in, and to provide adequate instruction in the safe operation of the vessel on the waters where it is intended for use. The licensing authority (where there is one) also has a duty both to the hirer and the hire operator to assure itself that licenses are issued only to operators meeting and maintaining the standards of this code.
2.1 The Hirer
The hirer has responsibilities which include:
a) Nominating a party leader (the ‘Skipper’, who may not be the same person who made the booking.)
b) The skipper and any other party member nominated to drive or handle the boat must attend the handover briefings (see section 5) and take heed of the advice and instruction given.
c) Be familiar with the safety features and instructions given during the safety briefings.
d) Navigate in accordance with the advice and instructions given (in whatever form including written, verbal, signage) by the hire operator and the body responsible for the waters to be navigated.
e) Study the briefing material provided.
f) Use safety equipment as instructed.
g) Ensure that young people or those with special needs are appropriately supervised (Appendix 1 has more information for special needs and educational parties)
2.2 Hire Operator
The hire operator will:
a) Ensure their vessels comply with this Code and are maintained in that condition. (see section 6)
b) Provide handover briefings
c) Not permit vessels to depart if they consider that the crew does not have sufficient competence to navigate without putting others at risk, or being able to control their passengers or crew. (Refer to appendix 1).
2.3 Licensing/Navigation authority
The body responsible for the navigation and/or licensing will:
a) Verify within the scope of their powers that hire vessels which they licence or regulate comply with the Code.(see section 6)
b) Where hire vessels or hire operators are not in compliance, take action within the scope of their powers to ensure that acceptable standards are achieved. (see section 6)
c) Overseeing as far as practicable, the use of licensed waters and taking action with those responsible when unacceptable or unsafe use is seen or reported to them.
Section 3: Risk Assessment
In common with other modern safety management standards, this code is based on an informed assessment of foreseeable risks and an informed judgement of whether the measures introduced to control those risks are proportionate and sufficient.
The technical and operational standards in this code are risk-based, having taken a view of incidents, accidents and foreseeable risks across the whole industry. In practice, the risks found with particular waterways, hire operators and hirers will vary from these industry ‘averages’. A process of risk assessment is therefore needed by the organisations with management responsibilities (navigation authorities and hire operators) to assess their local circumstances and decide whether risk controls additional to those set down in this Code are required.
A simple process of risk assessment is required to ensure that all risks in the local environment are being adequately addressed. Note that it is only necessary to specify standards above those set down in this code where increased local risks are judged to require them. The process should involve the persons with relevant knowledge and experience, and its results must be communicated to those who may be affected by it.
Some typical points to consider are as follows:
3.1 Hire Operators
A sample risk assessment format is given in appendix 4, however operators should use a risk assessment method which they feel comfortable with. Further guidance on risk assessment is available from the BMF.
3.2 Navigation/Harbour Authorities
As with all risk assessments it is important that they be kept under continual review and kept in step with any change that may affect safety (section 6, Change Control), and recorded (section 7, Record Keeping).
Section 4: Technical Standards
This section sets down the standards which apply to the design, construction and maintenance of the hire boat. All new hire craft will be expected to comply with these standards by [DATE]. Craft already in service as hire craft at [DATE] will be expected to be brought into compliance, where practicable, in accordance with section 4.5.
The standards are discussed in four groups, 4.1 to 4.4, below 5 :
4.1 Recreational Craft Directive. New craft within the scope of this Code must comply with the Recreational Craft Directive (RCD). The RCD applies to craft between 2.5m and 24 metres in hull length used for sport or leisure, including hire vessels, and constructed in the UK or anywhere else and first used within the EU on or after 16th June 1998. They may only be placed on the market in the UK or put into service use if they comply with the essential safety requirements set out in the Recreational Craft Regulations. Craft need to display a CE marking to show they satisfy conformity assessment procedures. Further information can be found at (references 8 and 9).
This Code requires hire operators to provide the licensing authority with evidence from a competent third party body of compliance with the principal requirements of the RCD6 . A model form for providing to the licensing authority is given in appendix 6.
4.2 Licensing Authority Standards.
Requirements for craft already in service relating to fires, explosion, ventilation, and the environment, are taken from the Boat Safety Scheme 7. The current Boat Safety Scheme requirements for privately owned boats were published in 2004. These are presented in three groups: mandatory, advisory, and best practice. Compliance with the mandatory requirements is necessary to obtain a private boat licence. These BSS requirements have been examined for relevance to hire boats taking into account the duty-of-care of the hire operator and likely level of knowledge and experience of the hirer. The results of this review are shown in reference 1. All the requirements which are mandatory for private boats have been carried over to hire boats. Non-mandatory private boat requirements have been reviewed in table 1, below for application to hire boats.
5 In due course it is intended to bring together the standards discussed at 4.2 to 4.4 together with the BSS standards for privately owned boats under the ownership of AINA acting on behalf of the National Water Safety Forum.
6 The BMF provide a service which independently verifies arrangements for demonstrating compliance with the RCD.

4.3 Stability and Freeboard Standards
The Breakaway V accident showed that in certain circumstances of load and distribution the ISO stability standard (BSS EN ISO 12217) mandated under the RCD could ‘pass’ conditions where stability margins were inadequate. With the support of MCA and AINA, the BMF have commissioned work to investigate the standard and recommend changes to address these issues. The completed work (appendix 5) is the basis for determining acceptable stability and freeboard standards under this Code.
In due course a revised ISO standard will be issued which could also be used to demonstrate adequate stability for the craft within its scope.
There are two levels of stability and freeboard testing, discussed in section 4.3.1.
4.3.1. Stability Testing.
(a) Initial Stability and Freeboard Test. These are applied to a representative sample of each design class when:
This Code comes into effect,
New or used boats are taken into hire service
Reference data or certification from a previous Initial Stability Test is not available.
Both tests shall be applied to an individual boat that has failed a check stability test.
(Refer to section 1.5, for further information on implementation dates)
Two types of stability test are available:
(i) The General Initial Stability Test explores the limits of a craft’s stability and must only be undertaken by persons competent to do so and working to a safe system of work. See 3.2 of Appendix 5 and consult the BMF Technical Department for more information8.
(ii) The Simplified Initial Stability Test (see 3.3 of Appendix 5) is available for boats operating on MCA Category A, B or C waters and which are:
The latter test is simplified, and may be conducted by suitably competent hire operator staff.
(b) Check Stability Test. This test will be carried out when any of the following apply:
After any change of engine type, internal or deckhouse arrangement, or the amount of ballast.
When any permanent weights of more than 3kg/metre of hull length are added or taken off, or any weight is added high up, e.g. adding or altering a mast.
8 BMF Technical Department reference www.britishmarine.co.uk
Check Stability Tests can be carried out by suitably competent hire operator staff. Further details of the test and competence required can be found in reference 10.Depending on the results of stability testing and the layout of the boat, Appendix 5 provides information on preventing or discouraging access to areas of a boat where the stability tests indicate a need to do so.
4.3.2. Open Powered Boats
Boats required to be marked with either of the labels shown in figures 3 or 4 of Appendix 5, section 3.2, shall not be permitted to operate in Category C or D waters.
(a) Fitted with Flotation
Flotation is a means of providing buoyancy to a swamped boat, e.g.air tanks or buoyancy bags.
Boats under 4m hull length may only be operated in Category A or B waters.
Boats fitted with flotation shall comply with and be tested to clause 6.4 and Annex B of ISO 12217-3, except that the One Person Test is not required for boats where the hull length is greater than 6m.
Note that freeboard requirements are higher where flotation is not fitted.
(b) Not fitted with Flotation.
Boats of this type can only operate in the following waters:
MCA Category A if more than 4m hull length.
MCA Category B if more than 4.5m hull length.
MCA Category C if more than 5m hull length.
MCA Category D – operation not permissible - Flotation essential.
(Note: Hull length LH is defined in ISO 8666 as the length from the forward side of the stem at gunwale level to the aftermost point of the watertight hull, measured parallel to the loaded waterline.)
4.3.3 Handover Procedures – Stability Aspects.
The following stability-related aspects are included in handover procedures, (references 12 and 13):
a) Open powered boats under 8m length (approx.). Not more than one person should be outside the cockpit at any time. In most circumstances all persons should remain in the cockpit at all times.
b) Open boats of LH less than 6m displaying the labels given in figures 4 or 5 of reference 10: Take care to keep the boat upright at all times. Excessive heel may swamp the boat or cause it to capsize.
c) Narrowboats. Where side-decks are provided, are of width not less than 75 mm and have a non-slip finish they may be used for occasional access to facilitate mooring, lock operation etc. They should not be regarded as providing a safe route along the boat.
No more than two (this may vary according to stability test results) persons to be on cabin roof at any one time. (Note: This requirement is in respect of stability issues only. It does not override other issues restricting access such as limited airdraft)
Because some gates leak water into the lock, there is a risk of swamping if the boat is too close to the upstream lock gate. Boats should keep back from leaking gates.
d) General. Restrict numbers of persons using the side decks and cabin roof in accordance with stability testing results (section 4.3).
4.4 Miscellaneous equipment
An examination of available accident and incident data has been used to determine the need for equipment and features additional to those referred to at 4.1 and 4.2 above. These are shown in table 2, below. This includes items applicable to hire boats covered in Part 10 of the 2002 BSS standards.
Download Hire Boats Code Table 2: Miscellaneous Standards. (PDF 115Kb)
4.5 Application to Existing Craft.
For existing craft which may not meet the standards described above, tables 1 and 2 show those items where deferred compliance, where practicable, is acceptable. The implementation plans for the Code, referred to in section 1.5, show the dates by which compliance is to be achieved.
Section:5 Operational Standards
This section is primarily concerned with the way in which boat hirers, who may have little or no previous experience, are provided with sufficient information and instruction to enable them to safely undertake the trip. It follows the stages of a trip through from booking, to departure from the hire base, to the conclusion of the trip.
(Note: This section is based on the national hire boat and day-boat handover schemes run by the British Marine Federation, references 12 and 13)
5.1 Pre trip information
Advanced booking gives an opportunity for the hire operator to provide the hirer with information both on navigating boats in general, such as using locks, rules of the road, mooring etc, and on the area in which they will be boating. General information is also available from some navigation authorities and industry associations9. Navigation Authorities will often produce cruising notes.
5.2 Handover procedures
Whether the boat is a large well-equipped cruiser designed to provide living accommodation for several weeks, or a simple day-boat, it is essential that before the hire operator gives control of the boat to the hirer a systematic and documented handover procedure, appropriate to the type of boat and its area of operation, is followed. This will cover topics which include:
a) Equipment.
Gas and electric appliances, and sanitary facilities.
b) Using the boat
Steering, stopping and mooring
Awareness of access limitations to ensure stability (see section 4.3.3 for detail)
Use of locks, swing bridges etc
Awareness of navigation hazards (e.g. weirs, tidal flows and/or river flows, commercial traffic, shallow water etc)
Speed limits
Restrictions to navigation notified by navigation or harbour authorities, or the MCA.
c) Safety Equipment.
Life jackets
Lifebuoys, throwlines etc
d) Briefing material
9 The Boaters Handbook. Published by British Waterways and the Environment Agency. Also available in CD ROM.
The handover should be supported by briefing material (a ‘Boat Manual’) left in the boat which provides full information on:
Personal safety
Safe use of appliances fitted in the vessel – cookers, stoves, heaters etc
Safety on the move
Safety equipment
Navigation rules, including speed limits, speed, giving way, etc.
Mooring (where and how)
Dealing with fouled propellers, going aground, etc
Navigation features and hazards such as locks, weirs,currents, tides etc
Detailed reference information on how the boat works
Contact information including for emergencies
e) Communications
Using the contact material in the boat manual.
f) Dealing with emergencies
Man overboard
Breakdown
Use of fire extinguishers/blankets
Emergency contact details
Recording and reporting
It is essential that the briefing is done by a competent and experienced member of the hire operators staff who can deal confidently with any questions the hiring party may have.
5.3 Competence Assessment
During or at the completion of the handover briefing, the hire operator must decide whether the hirer and his party are sufficiently competent to be allowed to take the boat out. Reasons for not doing so would include:
Throughout the handover process, the person giving the instruction should take account of any qualifications (for example, RYA Inland Helmsman) or previous experience professed by the skipper(s), however this should only be recognised as an opportunity to accelerate the briefing, not dispense with it.
5.4 During and after the Hire Period
At the conclusion of the hire period the hirer should have the opportunity , where practicable, to report back to the hire operator on any problems or incidents that occurred. These would include:
Hire operators must be aware of the statutory duty to report certain types of accident involving the use of hire craft to the Marine Accident Investigation Branch10 . In the interests of building a better understanding of boating accidents, their frequency and causes, hire operators are encouraged to pass on details through their navigation, or BMF, for inclusion in the IRIS database 11.
5.5 Documentation
The handover process is an essential element of delivering a safe boat trip to the hirer. It is important that an audit trail of its delivery is maintained. This will include:
5.6 Audit
In view of the importance of the handover process, hire operators are strongly recommended to have their handover arrangements independently audited every [X] years 12. Licensing authorities can reserve to right as part of licence conditions to carry out sample audits; having an independent audit available is likely to satisfy such a requirement.

12 The British Marine Federation offer an external audit service. www.britishmarine.co.uk Details of the service are also given at references 12, 13 and 14.
Section 6: Change Control
Changes to boats and the areas in which they operate inevitably occur and they need to be appropriately considered if the overall operation is stay in compliance with this Code. Hire operators and navigation authorities need to have processes in place which will ensure that the risks from any actual or proposed change are assessed and responded to appropriately.
6.1 Boats
Hire operators need to carefully consider whether any changes under consideration would lead to the boat falling out of compliance with the standards in this code. In particular they need to pay attention to those changes with the greatest potential for increasing risk. These include:
Any changes being considered must be assessed to ensure they will not increase risk or take the boat out of compliance with this Code. Changes must be carried by competent fitters in accordance with any statutory requirements such as Gas Safety (Installation and Use) and fully tested. The assessment should be simply documented to show that the change has been adequately considered. This can be done in a similar way to the risk assessment process - a simple form for this purpose is given in appendix 4.
7.2 Operational Changes.
Temporary or permanent changes to the area in which the hire boat operates could cause addition hazards which may require additional briefing of hirers, or restrictions to the area of operation. These could include:
Hire operators should ensure that they pay due heed to the available information sources such as navigation authority notices and bulletins, notices to mariners, extreme weather and flood alerts etc. Navigation and harbour authorities need to ensure they take reasonable measures to notify boat operators of hazardous conditions which they otherwise might not be aware of.
Risk assessments (section 3) need to be brought up to date accordingly, and the change recorded (appendix 4).
Section 7: Record Keeping
This section recommends the information that should be retained by hire operators and licensing/Navigation authorities. This will assist them if required to produce evidence of compliance with this Code. The following is recommended for document retention:
7.1 Hire Operator
(a) Safety Management Arrangements
Who has responsibility for safety, including handovers and the condition of boats (This could be covered by the safety policy statement produced under the Health and Safety at Work act.)
(b) Boat
Certificates and results of Initial and Check stability tests (retain for life of boat)
GSIUR certificates
Certifying authority certificates, e.g.BSS.
Inspection records
Major maintenance and inspection records
Change/modification records
(c) Operations
Booking terms and conditions, and confirmations.
Who received and delivered handover briefings
Incidents and accidents reported by operators, hirers, and third parties
Boat manuals, or briefing notes.
Customers log sheets (when the hirer and his party arrived on board and were briefed, names of party,etc)
Boat Acceptance Certificates
Accident/Incident Reports
Handover procedures
7.2 Licensing/Navigation/Harbour Authorities
Section 8: Review
The BMF, AINA, and the MCA will form a small review team who will:
Formal reviews will be carried out annually and reported on the host organisations’ websites. Every effort will be made to avoid a substantive re-issue within the first three years of its implementation.

BMF / MCA HIRE BOAT CODE
STABILITY, BUOYANCY & FREEBOARD REQUIREMENTS
PART 1 – POWERED CRAFT
1 GENERAL
1.1 Scope
These requirements apply to power-driven boats, including:
Personal watercraft, human propelled boats and sailing boats fitted with engines are not included.
1.2 Definitions
The following definitions apply:
Child: person weighing less than 37.5kg (approximately 1.2m height).
Day-hire boat: a boat not fitted with overnight accommodation (bunks and cooking facilities).
Decked Boats: boats fitted with a watertight deck or rigid cabin top covering at least 70% of the plan area at deck level. Sliding or lifting rigid cabin tops may be included in the area described as “decked”. Boats with a rigid canopy over an open well are considered to be Open Boats unless the sides are enclosed by rigid structure.
Design Class: a design of boat that has the following:
(a) Common hire operator.
(b) Relies on the same Initial Stability Test and Initial Freeboard Test.
(c) The same hull form.
(d) The same arrangement of seating, cockpit, decking and superstructure.
(e) The same location and weight of major masses (e.g. ballast, engines, batteries, fuel and water tanks).
(f) The same limitations on numbers of persons and accessible areas.
(g) The same interior arrangement and outfit.
(h) The same positions of critical downflooding openings.
Different sub-classes (or models) may be created where changes are made to d) e) or f) above. The change will require a Check Stability Test to be carried out. If this shows that a fresh Initial Stability Test is required then the boat will be regarded as a new design class.
Flotation: means of providing buoyancy to a swamped boat, eg: air tanks, buoyancy bags.
Freeboard: the least height (when the boat is upright) from the loaded waterline to any opening that may admit water into the interior or non-self-draining part of the boat (also known as downflooding height).
Freeboard margin: the minimum freeboard measured when heeled during the Initial Stability Test.
Hire operator: Person or organisation offering boats for hire (includes time-share operators).
Hirer: Person hiring the boat from the hire operator.
Length of Hull (LH): length of boat from the forward side of the stem at gunwale level to the aftermost point of the watertight hull, measured parallel to the loaded waterline.
Narrowboat: a boat with a maximum beam of 2.08m (6 feet 10 inches) and designed for the narrow waterways and canals.
Open Boats: all boats that are not Decked Boats.
Pontoon Boat: day-hire boat comprising a platform mounted on two cylindrical sealed hulls.
Powered Boats: boats powered by internal (ie: spark or compression ignition) or external combustion engines (eg: steam engine) or electric motors and not fitted with sails.
Seating Place: a place where people can be seated, minimum width 500mm, with legroom appropriate to its height. It may be a dedicated seat or bench, a bunk, sun pad or (in Canoes, Dinghies or Punts) the bottom boards.
Significant wave height: average height of the highest one third of the waves, unless otherwise indicated.
NB:Where any of the foregoing definitions differ from the Hire Boat Code, the definitions given above shall be utilised when applying these requirements
2. GENERAL STABILITY & FREEBOARD REQUIREMENTS
2.1 General
(a) Except in relation to freeboard (also known as downflooding height), references to:
Design Category C in ISO 12217 shall be taken as applicable to MCA Categories C and D.
Design Category D in ISO 12217 shall be taken as applicable to MCA Categories A and B.
(b) Even where ISO 12217 is being utilised, the freeboard requirements of section 4 shall apply to boats assessed using this Code instead of those in ISO 12217.
(c) Where reference is made to an ISO standard, the relevant definitions and requirements in the document being used shall apply unless they differ from those in this Code, in which case the latter shall apply.
(d) The maximum number of persons shall not exceed the number of available Seating Places.
(e) Where limits are placed on the number of persons based on plan area, figures calculated shall be rounded up if the first decimal place is 5 or more, otherwise rounded down.
(f) Day-hire boats unable to satisfy all the requirements for Category B, but meeting the requirements for Category A, may be operated in Category B waters provided that they do so in conditions not exceeding 20 knots of wind and wave heights of 0.1m significant. When this option is exercised, the hire operator shall maintain daily records of the wind and wave conditions during periods when boats are being hired out.
(g) Where boats are hired out to groups of young people or groups of mixed ages, the total number of persons permitted by this Code may be exceeded provided that the total weight of persons using the boat does not exceed the number permitted by this Code multiplied by 75kg.
2.2 Decked Powered Boats
The stability of decked powered boats shall be assessed using the stability test procedure given in section 3.
The maximum number of persons on the boat, excluding the number permitted on cabin top or side-deck, shall not exceed twice the total plan area (in m2) of cockpits that are either open to the air or equipped with portable means of shelter (sliding tops, canvas covers, etc).
Minimum freeboard shall comply with sections 4.1 and 4.2.
Pontoon boats may only be given MCA Category A or B.
2.3 Open Powered Boats
The stability of open powered boats shall be assessed using the stability test procedure given in section 3. During the test, persons may be restricted to cockpits or wells.
The maximum number of persons on the boat shall not exceed twice the total plan area (in m2) of cockpits that are either open to the air or equipped with portable means of shelter (sliding tops, canvas covers, etc).
Minimum freeboard shall comply with sections 4.1 and either 4.3 or 4.4 according to whether or not flotation is fitted. The following open powered boats must comply with the flotation requirements of 6.4 and Annex B of ISO 12217-3:
Where flotation is fitted, boats shall comply with clause 6.4 and Annex B of ISO 12217-3, except that the One Person Test is not required for boats where LH is greater than 6m. Freeboard requirements are higher where flotation is not fitted.
Boats under 4m length may not be operated outside of MCA Category A or B waters.
Boats required to be marked with either of the labels shown in Figures 3 or 4 (section 3.2) shall not be operated in Category C or D or coastal waters unless a support boat and crew are immediately available.
2.4 Plan of Stability and Freeboard Testing
Power-driven boats shall be subjected to the following tests:
2.4.1 Initial Stability Test and Initial Freeboard Test.
These tests shall be applied to a representative sample boat of each Design Class when:
Both tests shall be applied to an individual boat that has failed a Check Stability Test.
The Initial Stability Test explores the limits of a craft’s stability and must only be undertaken by persons competent to do so and working to a safe system of work. Consult the BMF Technical Department for more information13. Further details can be found in Section 3 of these requirements.
Further details of the Initial Freeboard Test can be found in Section 4.1 of these requirements.
2.4.2 Check Stability Test.
This test shall be carried out on any boat when any of the following apply:
If the Check Stability Test does not adequately repeat the measurements made during the Initial Stability Test, the latter test is to be conducted on the boat in question.
Check Stability Tests can be carried out by suitably competent hire operator staff. Further details of the test can be found in Section 3.3 of these requirements.

3 STABILITY TESTING OF POWERED BOATS
3.1 General
(a) The Offset Load Test used in ISO 12217 Parts 1 and 3 as amended shall be accepted as equivalent, provided that data to enable Check Stability Tests to be undertaken has been recorded.
(b) Every boat of a class used by a given hire operator shall have the bow and stern freeboard measured prior to every new season. When this check is made the boat shall be in the loading condition described in 3.2.1(b).
(c) The Crew Area comprises the areas of the boat in which persons may be safely located when the boat is in use, and comprises all areas defined by the Hire Operator for people to stand, walk, sit or lie during normal operation of the boat including internal decks. On some boats it may be limited to the cockpit, but it must always include all of the primary cockpit. The Crew Area of each class of boat is to be identified in the Hire Operator’s documentation and on a diagram placed at the main control position – see Figure 1.
(d) If the Hire Operator chooses to assess the stability by excluding some areas from the Crew Area or limiting the number of people on any given area, such areas are to be listed in the Hire Operator’s documentation and physically marked with “do not access” or “limited access” signs as illustrated in Figures 2 and 3.In addition a diagram identifying such areas and their access limitations shall be placed at the main control position – see Fig 1.
(e) The lettering on Figure 1 shall be a minimum of 3mm high. Figures 2 and 3 shall have a minimum vertical dimension of 30mm and shall be placed where they are clearly visible. Each label shall comprise a rigid plate or flexible label affixed to the craft in such a way that it can only be removed by the use of tools.

3.2 General Initial Stability Test Procedure
3.2.1 General
(a) This procedure applies to the first boat tested of each Design Class that is identical in its class. For details of Check Stability Tests see 3.5.
(b) Ensure that the bilges of the boat are pumped as dry as practicable and fuel, water and other tanks are between about 25% and 75% full. The boat should be fitted with all normal operating equipment, and outboard motor if appropriate. No personal gear should be on board.
(c) Record the freeboard on the centreline at both bow and stern, and clearly record the position to which these freeboards have been taken, and whether the boat is in salt or fresh water. These measurements are referred to as the Datum Freeboards.
(d) Load the boat with all personal effects, stores and baggage to be carried. At least 5kg/person shall be added for open boats, and 20kg/person be added for boats with overnight accommodation or for boats used for camping trips.
(e) During the tests, on boats with watertight or quick-draining cockpits, water may enter the cockpit through drains when the boat is heeled during the test, provided this water drains overboard when the test weights are moved to the centreline.
(f) The freeboard margin is, when the boat is heeled, the vertical height from the waterline to the point at which water could first begin to enter the interior or bilge. Where a hull fitting is connected to a pipe, the highest point of the pipe is the height to be measured. Pipes through which water cannot enter the interior or bilge (eg: exhaust pipes, pipes with non-return valves) can be disregarded.
(g) During the tests, when measuring the freeboard margin, one outboard engine well penetration fitted with a sealing boot may be disregarded.
(h) All applicable boats must be tested according to 3.2.2. Open power-driven boats of less than 6m LH shall also be tested according to 3.2.3.
3.2.2 Procedure for General Initial Stability Test
(a) Assemble a group of people up to a total weight of 98n kg (where n = number of persons the boat is intended to carry). Record the weight of each person. Alternatively, an 85kg set of test weights may be used instead of each person.
NOTE 85kg includes a margin of 13% to allow for the probability that a group of persons may weigh on average more than 75kg each
(b) For boats in which all parts of the Crew Area are below the sheerline, successive persons shall be placed on board so as to result in the least freeboard margin in each case. For all other boats two tests shall be conducted: the first with persons placed so as to result in the maximum heel angle, After completion of this, the persons are to be moved to the positions (using the criteria of (g) below) that result in the least freeboard margin. If the measured freeboard does not satisfy Table 4, remove people or sets of test weights until this is achieved, whilst maintaining the most adverse positioning of the remainder.
(c) For each test use the following procedure. Where the crew limit is expected to exceed seven persons, up to 25% of the crew limit may be added at each of the first two stages. Successive stages of a physical test should not exceed one person.
(d) Where people are standing, as far as practicable they should remain upright without exerting much weight on any handholds. When the tester is onboard the boat, he/she should stand on the centreline as close as practicable to the centre of area of the waterplane, so that their presence does not affect the trim, and always stand in the same position when measurements are taken. Their weight may be offset against the mass of carry-on load. Persons measuring freeboards should not be on board the boat being tested.
(e) Place the first person at the main control position, as far outboard as practical but not closer than 200mm from the outboard edge. Measure the heel angle and freeboard margin (see 3.2.1 (f) and (g)).
(f) Repeat in the opposite direction of heel unless it is clear from any assymetry of the boat that the first direction is most onerous, when only this direction need be tested. The most adverse of the two measurements of each parameter made are to be recorded.
(g) Place an additional person to one side of the Crew Area. The centre of gravity of each person shall be positioned as far to one side as practicable, provided that adjacent people are not placed with their centres-of-gravity closer than 500 mm apart in any direction, or closer than 200 mm from the outboard edge of the Crew Area, except where the deck is less than 400mm wide when practical positions are to be used .
(h) Measure the heel angle and least freeboard margin. Repeat in the opposite direction of heel unless it is clear from any assymetry of the boat that one direction is most onerous, when only this direction need be tested. The most adverse of the two measurements made are to be recorded.
(i) Repeat (e) and (f) for further increments of not more than one person at a time, whilst observing the Hire Operator’s definition of Crew Area according to 3.1 (c) and (d). Stop the test when the first of the following events happens:
NOTE: The safe loading of a boat may be limited by any of these factors and there is no safe method of determining in advance which is the limiting factor for a given boat. Therefore all need to be considered and the test stopped when the first of them occurs.
Caution: Great caution must be exercised when doing this test because some boats may capsize suddenly. Therefore heeling moments should be increased carefully, especially when approaching the expected Crew Limit. As this point is approached, smaller increments of test weights should be used. In smaller boats it is helpful to attach a capsize preventer rope (eg: from the depressed gunwale to a strong point ashore) provided that this is kept slack enough not to interfere with the test. For larger boats, to give warning of loss of stability, a continuously plotted graph of heel angle against heeling moment (product of the mass of test weights times the distance off the centreline measured parallel to the design waterline) should be used.
Caution: Because of the risk of capsize, sets of test weights should be used instead of persons in any locations from which escape would become hazardous should the boat capsize.
(j) Of the measurements made according to (c), (e) or (h), the maximum heel angle recorded shall be less than that given in Table 5, and the minimum measured freeboard margin recorded shall exceed the requirement given in Table 4.
(k) If the test is limited by downflooding over the gunwale, the maximum number of persons allowed is calculated as the maximum actual mass of persons on board, divided by 85kg per person, rounded downwards to the nearest child (or adult).
(l) If the test is limited by maximum heel angle, loss of stability or downflooding through openings in the topsides, the maximum number of persons allowed is calculated as the maximum actual mass of persons on board, divided by 98kg per person, rounded downwards to the nearest child (or adult).
NOTE: 98kg incorporates a 15% stability margin for persons weighing 85kg each, or 30% for persons weighing 75kg each.

(m) When the crew limit has been found, return to a loading condition in which between 40% and 60% of the crew limit are on board, positioned as during the test above. Record the weight and positions (lengthwise and athwartships) of each of the people on board, the consequent heeling moment applied, and the measured heel angles and freeboard margins for later comparison with Check Stability Tests conducted in accordance with 3.4.
(n) Where an open power-driven boat of LH less than 6m of Category A or B is unable to comply with the test above when using people, it may be retested using a set of test weights totalling (85 x LH / 6) kg in respect of each person, in which case the crew limit shall be calculated as in (j) and (k) but using (85 x LH/6) instead of 85 and (98 x LH / 6) instead of 98 respectively.
(o) If the boat passes this revised test, a label as shown in Figure 4 shall be displayed on the boat. This label shall have a minimum vertical dimension of 50mm and shall be placed where it is clearly visible when entering the boat. It shall be a rigid plate or flexible label affixed to the craft in such a way that it can only be removed by the use of tools.
NOTE The use of water containers instead of metallic test weights will give a less advantageous result.

3.2.3Gunwale Load Test
(a) This test is only applicable to open powered boats of LH less than 6m.
(b) Apply a vertically downwards load of 85kg to the gunwale of the boat without crew at LH /2 forward of the stern. If this load is applied by suspending a test weight in the water, the dry mass of the test weight must be 85d, where d is a material coefficient as given in Table 6.
NOTE 85 kg includes a margin of 13% to allow for the probability that a person may weigh on average more than 75kg.

| material | lead | 65/35 brass | steel | cast iron | aluminium |
| value of d | 1,099 | 1,138 | 1,151 | 1,163 | 1,162 |
(c) If the boat swamps or capsizes under this load, a warning label as shown in Figure 5 shall be displayed where it is clearly visible when entering the boat. This label shall have a minimum vertical dimension of 50mm and shall be a rigid plate or flexible label affixed to the craft in such a way that it can only be removed by the use of tools.

Do not sit or stand on the gunwale
3.3 Simplified Initial Stability Test (draft)
(a) This test is only applicable to boats which operate on MCA Category A, B or C waters and which are:
(i) 2.08m beam cruising narrowboats over 10m in length, or
(ii) decked power-driven boats over 7m in length and which satisfy the following:
maximum height of deck or coachroof on which crew members may sit or stand is less than [50]% of the maximum hull beam (excluding rubbers), and
maximum number of persons is less than (LH x B x B)/15, where LH is the length of hull and B is the maximum hull beam excluding rubbers.
(b) This test may be conducted by suitably competent hire operator staff.
(c) This procedure applies to the first boat tested of each Design Class that is identical in its class. If in any doubt as to whether the weight of ballast fitted or downflooding openings are the same, first conduct the Check Stability Test to confirm this. For details of Check Stability Tests see 3.4.
(d) Before conducting Initial Stability Test, prepare the boat in accordance with 3.2.1(b), (c) and (d).
(e) Identify all points in the topsides through which water may flood the interior of the boat (downflooding points). In particular identify those openings with the least height above the waterline. Engine exhausts can be ignored. For openings piped internally, the critical height is to the highest point reached before downflooding begins. On narrowboats the forward door from the bow cockpit is often critical. In such cases if the bow cockpit is watertight, the downflooding point is the door sill.
(f) Where the minimum upright freeboard to critical downflooding openings when the boat is fully loaded with the maximum number of persons onboard at 75kg each is greater than that given in Table 7 or 8 below, no further action is required. In using this table, boat length should be rounded down, and beam rounded up to the nearest figures tabulated.

Where the minimum upright freeboard to critical downflooding openings when loaded as described above is NOT greater than that given in Table 7 or 8, then the procedure below must be followed.
(g) Assemble a group of persons weighing not less than 98n (kg), where n is the maximum number of persons the boat is intended to carry. Check their total weight using scales.
(h) Mark the mid-length of the hull of the boat, excluding bow/stern fittings or rudder.
(i) Position the group of persons on the side-deck, evenly fore-and-aft about the mid-length, and standing as upright as practicable, holding on lightly if necessary.
(j) Measure the angle of heel and the vertical freeboard margin to the most critical downflooding points forward and aft. BMF Technical Department can advise simple ways of measuring the heel angle.
(k) If the angle of heel is less than that given in Table 5 above, and the freeboard margin is more than [150]mm for Category A or B waters, or [200]mm for Category C waters, the boat has passed.
(l) If the boat fails to meet these parameters, either:
(m) If the number of persons has been reduced, the crew limit is the total weight in kg of those finally on board, divided by 98.
(n) After the maximum number of persons on board has been found, gather data for the Check Stability Test as follows.
(o) Find the total weight of a group of approximately half the maximum acceptable number of persons that has been found.
(p) Repeat the measurements in (i) when this reduced number of persons is positioned on the side-deck evenly about the mid-length, and record the heel angle and freeboard margin fore and aft for comparison with future Check Stability Tests.
3.4 Check Stability Test
(a) This procedure applies to Check Stability Tests only. For details of tests to be applied to the first boat tested of each Design Class see 3.2 or 3.3.
(b) Before conducting Check Stability Tests, prepare the boat in accordance with 3.2.1(b), (c) and (d).
(c) Replicate the total weight of people / weights and total heeling moment as recorded for this test during the Initial Stability Test (see 3.2.2(m) or 3.3(o)).
(d) The resulting maximum heel angle and minimum heeled freeboard requirements shall then be compared with those of the initial heeling moment during the Initial Stability Check – see 3.2.2 (i). If, for the same total mass of persons added, the original heel angle is exceeded by more than 2% or the original freeboard margin is not attained, then the safe Crew Limit is to be reassessed using the Initial Stability Test procedure as 3.2 or 3.3 above (as was originally used for the boat) in its entirety.
4 FREEBOARD REQUIREMENTS
4.1 Initial Freeboard Test
4.1.1 Freeboard is the least vertical height from the loaded waterline (at design trim and no heel) to any opening in the hull (including the edge of a coaming) that may admit water into the interior or bilge of a boat or a recess. Such openings are called “downflooding openings”.
4.1.2 Freeboard shall be measured when the boat is loaded with:
(a) all normal operating equipment,
(b) outboard motor if appropriate,
(c) full fuel and water tanks (or weights to make up any missing quantity),
(d) a weight of 75kg for each person to be carried, located in practical positions (ie: on thwarts and seats where appropriate) so as to produce a sensible operating trim, ie: slightly stern down (if practicable).
(e) at least 5kg/person allowance for personal effects shall be added for day-hire boats, and 20kg/person be added for boats with overnight accommodation or those used for camping trips.
4.1.3 When a boat has no downflooding openings, the minimum freeboard to the main deck shall not be less than 80% of the requirements of 4.2.
4.1.4 The requirements given in 4.2, 4.3 and 4.4 apply to all downflooding openings except:
(a) engine exhausts or other openings that are only connected to watertight systems;
(b) openings in the sides of outboard engine wells which are of
NOTE: Degrees of watertightness and means of testing are given in ISO 12216.
4.1.5 Downflooding openings may exist inboard of theside shell, eg: door sills, hatches, outboard engine trunks, sinks or drains piped to hull fittings.
4.1.6 Where the flow of water to a downflooding point inboard of the side shell is restricted by drainage holes, channels or pipes with a total cross-section area of less than 20cm2, the freeboard shall be not less than 70% of that required by 4.2 to 4.4 below.
EXAMPLES: Sink drains, cabin doors leading from bow cockpits on narrowboats, bilge pump outlets.
NOTE:It is recommended that doors from bow cockpits on narrowboats (which may be vulnerable to swamping from leaking lock gates) should have a minimum sill height of 75mm above the cockpit sole.
