发明名称 Boat construction incorporating flotation means
摘要 A small boat or the like comprising a flotation chamber defined at its gunwale by a first member, preferably integral with the sides of the hull extending upwardly and defining an upper end portion which may include a reverted first member lip, a second member or cover secured at its bottom portion to the hull, the major portion of which is spaced laterally from the first member with its upper end portion extending over the first member and including a reverted second member lip, and a connecting device resiliently engaging the upper end portion or first member lip with the second member lip to secure a flotation material in the form of a block of expanded polystyrene or the like within the flotation chamber. The connecting device can be a separate element pressing the lip of the first and second members against each other or can be a resilient portion of one of the members normally biasing the two members into engagement. A rub rail is defined at the upper end of the flotation chamber and can be formed either by a separate connecting member or by a portion of one of the other members.
