INSTALLATION REQUIREMENTS 5.1. Engines and engine spaces 5.1.1. Inboard engine All inboard mounted engines shall be placed within an enclosure separated from living quarters and installed so as to minimize the risk of fires or spread of fires as well as hazards from toxic fumes, heat, noise or vibrations in the living quarters. Engine parts and accessories that require frequent inspection and/or servicing shall be readily accessible. The insulating materials inside engine spaces shall be non-combustible. 5.1.2. Ventilation The engine compartment shall be ventilated. The dangerous ingress of water into the engine compartment through all inlets must be prevented. 5.1.3. Exposed parts Unless the engine is protected by a cover or its own enclosure, exposed moving or hot parts of the engine that could cause personal injury shall be effectively shielded. 5.1.4. Outboard engines starting All boats with outboard engines shall have a device to prevent starting the engine in gear, except: when the engine produces less than 500 newtons (N) of static thrust; when the engine has a throttle limiting device to limit thrust to 500 N at the time of starting the engine. 5.2. Fuel system 5.2.1. General The filling, storage, venting and fuel-supply arrangements and installations shall be designed and installed so as to minimize the risk of fire and explosion. 5.2.2. Fuel tanks Fuel tanks, lines and hoses shall be secured and separated or protected from any source of significant heat. The material the tanks are made of and their method of construction shall be according to their capacity and the type of fuel. All tank spaces shall be ventilated. Liquid fuel with a flash point below 55 °C shall be kept in tanks which do not form part of the hull and are: insulated from the engine compartment and from all other source of ignition; separated from living quarters. Liquid fuel with a flash point equal to or above 55 °C may be kept in tanks that are integral with the hull. 5.3. Electrical system Electrical systems shall be designed and installed so as to ensure proper operation of the craft under normal conditions of use and shall be such as to minimize risk of fire and electric shock. Attention shall be paid to the provision of overload and short-circuit protection of all circuits, except engine starting circuits, supplied from batteries. Ventilation shall be provided to prevent the accumulation of gases which might be emitted from batteries. Batteries shall be firmly secured and protected from ingress of water. 5.4. Steering system 5.4.1. General Steering systems shall be designed, constructed and installed in order to allow the transmission of steering loads under foreseeable operating conditions. 5.4.2. Emergency arrangements Sailboat and single-engined inboard powered motor boats with remote-controlled rudder steering systems shall be provided with emergency means of steering the craft at reduced speed. 5.5. Gas system Gas systems for domestic use shall be of the vapour-withdrawal type and shall be designed and installed so as to avoid leaks and the risk of explosion and be capable of being tested for leaks. Materials and components shall be suitable for the specific gas used to withstand the stresses and exposures found in the marine environment. Each appliance shall be equipped with a flame failure device effective on all burners. Each gas- consuming appliance must be supplied by a separate branch of the distribution system, and each appliance must be controlled by a separate closing device. Adequate ventilation must be provided to prevent hazards from leaks and products of combustion. All craft with a permanently installed gas system shall be fitted with an enclosure to contain all gas cylinders. The enclosure shall be separated from the living quarters, accessible only from the outside and ventilated to the outside so that any escaping gas drains overboard. Any permanent gas system shall be tested after installation. 5.6. Fire protection 5.6.1. General The type of equipment installed and the layout of the craft shall take account of the risk and spread of fire. Special attention shall be paid to the surroundings of open flame devices, hot areas or engines and auxiliary machines, oil and fuel overflows, uncovered oil and fuel pipes and avoiding electrical wiring above hot areas of machines. 5.6.2. Fire-fighting equipment Craft shall be supplied with fire-fighting equipment appropriate to the fire hazard. Petrol engine enclosures shall be protected by a fire extinguishing system that avoids the need to open the enclosure in the event of fire. Where fitted, portable fire extinguishers shall be readily accessible and one shall be so positioned that it can easily be reached from the main steering position of the craft. 5.7. Navigation lights Where navigation lights are fitted, they shall comply with the 1972 Colreg or CEVNI regulations, as appropriate. 5.8. Discharge prevention Craft shall be constructed so as to prevent the accidental discharge of pollutants (oil, fuel, etc.) overboard. Craft fitted with toilets shall have either: holding tanks; or provision to fit holding tanks on a temporary basis in areas of use where the discharge of human waste is restricted. In addition, any through-the-hull pipes for human waste shall be fitted with valves which are capable of being sealed shut.
