Sound dampening, hull stiffening, and 100% unsinkable even if the hull is holed in every flotation compartment.

2 lb per cubic foot expanding pourable foam for filling forward flotation compartments and subfloors. Adds 40-60# of weight to the hull, depending upon which flotation compartments you choose to foam.

Should be purchased and installed prior to closing up your hull.

NOTE: The Puur 17 contains 6 isolated flotation compartments, which make the boat unsinkable except in the highly-unlikely case of simultaneous holing of several compartments. We recommend this foam primarily for its sound-deadening and hull stiffening qualities.
