3.INTEGRITY AND STRUCTURAL REQUIREMENTS
3.1.Structure
The choice and combination of materials and its construction shall ensure that the watercraft is strong enough in all respects. Special attention shall be paid to the design category in accordance with Section 1, and the manufacturer’s maximum recommended load in accordance with point 3.6.
3.2.Stability and freeboard
The watercraft shall have sufficient stability and freeboard considering its design category in accordance with Section 1 and the manufacturer’s maximum recommended load in accordance with point 3.6.
3.3.Buoyancy and flotation
The watercraft shall be constructed as to ensure that it has buoyancy characteristics appropriate to its design category in accordance with Section 1 and the manufacturer’s maximum recommended load in accordance with point 3.6. All habitable multihull recreational craft susceptible of inversion shall have sufficient buoyancy to remain afloat in the inverted position.
Watercraft of less than 6 metres in length that are susceptible to swamping when used in their design category shall be provided with appropriate means of flotation in the swamped condition.
3.4.Openings in hull, deck and superstructure
Openings in hull, deck(s) and superstructure shall not impair the structural integrity of the watercraft or its weather tight integrity when closed.
Windows, port lights, doors and hatch covers shall withstand the water pressure likely to be encountered in their specific position, as well as point loads applied by the weight of persons moving on deck.
Through hull fittings designed to allow water passage into the hull or out of the hull, below the waterline corresponding to the manufacturer’s maximum recommended load in accordance with point 3.6, shall be fitted with a means of shutoff which shall be readily accessible.
3.5.Flooding
All watercraft shall be designed so as to minimise the risk of sinking.
Where appropriate, particular attention shall be paid to:
(a)
cockpits and wells, which should be self-draining or have other means of keeping water out of the watercraft interior;
(c)
removal of water by pumps or other means.
3.6.Manufacturer’s maximum recommended load
The manufacturer’s maximum recommended load (fuel, water, provisions, miscellaneous equipment and people (in kilograms)) for which the watercraft was designed, shall be determined in accordance with the design category (Section 1), stability and freeboard (point 3.2) and buoyancy and flotation (point 3.3).
3.7.Life raft stowage
All recreational craft of design categories A and B, and recreational craft of design categories C and D longer than 6 metres shall be provided with one or more stowage points for a life raft (life rafts) large enough to hold the number of persons the recreational craft was designed to carry as recommended by the manufacturer. Life raft stowage point(s) shall be readily accessible at all times.
3.8.Escape
All habitable multihull recreational craft susceptible of inversion shall be provided with viable means of escape in the event of inversion. Where there is a means of escape provided for use in the inverted position, it shall not compromise the structure (point 3.1), the stability (point 3.2) or buoyancy (point 3.3) whether the recreational craft is upright or inverted.
Every habitable recreational craft shall be provided with viable means of escape in the event of fire.
3.9.Anchoring, mooring and towing
All watercraft, taking into account their design category and their characteristics, shall be fitted with one or more strong points or other means capable of safely accepting anchoring, mooring and towing loads.
