There must be one Type I, II, III, or V PFD for each person on board or being towed on water skis, etc., PLUS one Type IV throwable device. Throwable devices must be immediately available for use. Wearable PFDs must be readily accessible, not stowed in bags, locked or closed compartments or have other gear stowed on top of them. Recreational boats must carry Coast Guard approved Personal Flotation Devices, in good and serviceable condition, and of the appropriate size for the intended user. COAST GUARD MINIMUM EQUIPMENT REQUIREMENTS Cleaning with soap and water is the best way to maintain its effectiveness. Elements must be clean, and grids must be tight enough to prevent flames passing through. When in use flame arrestors must be secured to the air intake of the carburetor with an airtight connection. It operates by absorbing heat.įlame arrestors no longer require Coast Guard approval the USCG now accepts flame arrestors complying with Underwriters Laboratories Standard 1111 or Society of Automotive Engineers J1928. With some minor and technical exceptions, every inboard gasoline engine must be equipped with an acceptable means of backfire flame control-or "flame arrestor." This safety device prevents an exhaust backfire from causing an explosion. It is recommended that you use a blower at least 4 minutes before you ever start the engine, and especially after fueling. The size blower you need is determined by the volume of your engine compartment. They are ignition protected to prevent sparks, and are built to resist overheating and corrosion. The USCG stipulates the use of a mechanical ventilation system for all non-open boats built after Jthat run on gasoline.Įven if your boat is older, it still must conform to USCG minimum ventilation levels, and may require a bilge blower to satisfy those guidelines.īilge Blowers are specifically designed to clear gasoline fumes from closed compartments. For most boats that works out to having two inlets and exhausts, with each vent having ducting from 3 inch diameter hose for smaller boats to 5 inch hose for larger boats.Ī bilge blower is important not only because it's required, but because your life may depend on it. Larger boats with larger compartments must have more ventilation-the figure is 15 square inches of opening for each cubic foot of compartment. (Birds like to make nests in ducts.) Intakes are usually pointed forward, exhausts usually face aft.īoats must have a ventilation system that is adequate for the size space the system is used for. Ducting should be routed away from any heat sources, should not be "kinked", and should be inspected regularly for cracks or debris. Ducting for the exhaust must be located in the lower third of the hull-but above any bilge water. Both the inlet and the outlet must have ducts-which are tubes or hoses that extend down into the boat. Ventilation systems must have two parts-an air inlet, and a separate air outlet. Good ventilation can do many things for you-help prevent mildew and bad odors, to saving your life by taking carbon monoxide and gasoline fumes out of the boat. If you have any gasoline powered engines aboard a ventilation system is a legal requirement. If you have enclosed areas on your boat, a ventilation system can do many things for you.
