Flotation foam is any type of foam designed or repurposed for use in marine vessels and docks for the purpose of flotation enhancement, thermal insulation, and for sound deadening. You can find specially designed boat flotation options in the form of pourable foam, closed-cell foam mats or blocks, and even boat foam pods that attach to the ...
Sunlight went to help out Land or Sea and kept there docks from sinking. Using closed cell spray foam you can make anything float. www.sunlightcontrac...
The marine environment can be challenging, but expanded polystyrene EPS floatation blocks have withstood the test of time. Often confused with STYROFOAM Brand Foam, EPS is lightweight and extremely buoyant, can be shaped and molded to fit the demand of marine construction and it holds up under year around environmental conditions.
F or flotation purposes, distribute the foam as much as possible so the boat will float nearly level if holed. If all the foam were placed forward, for example, the stern would sink and the bow would stick up, perhaps nearly vertically. However, flotation should be concentrated near items of negative buoyancy, such as engines, batteries, etc.
Your boat has passed a flotation test performed by the manufacturer to U.S. Coast Guard standards. Your boat is protected if not loaded over the Max. Weight Capacity. The lo ion of the foam in the boat is such that if the boat swamps or fills with water, it will still float level enough and high enough to minimize exposure to 40 degree water.
Fb = Amount of Flotation need to support the swamped boat Fp = Flotation needed to support propulsion equipment Fc = Flotation needed to support persons and dead weight B = 62.4 For Air Chambers 28.3 KG B = 60.4 For 2 pound density foam fresh water 27.4 KG
Natural-Therm Flotation Foam Specs. Natural-Therm 2250 high-yield, expanding marine foams have exceptional physical properties. Their high-yield and ease of use make them great for filling voids. The chart below shows the relationship between applied pass thickness, polyurethane foam-in-place density, and compressive strength.
Flotation foam for Boats In the spring and early summer, we receive a volume of inquiries from folks with older boats wanting to install or replace foam for flotation. This customer in Buford, GA purchased 4 blocks of 1 lb density EPS 6” x 24” x 72” and cut them to fit in the hull of his row boat.
