摘要

The craft has upper and lower parts closed at front and rear, respectively, and a coaming located between the parts. A sealed buoyancy compartment (2) i.e. buoyancy tank, is provided at interior of a hull (4), where the hull is made of polyethylene by rotative casting. A part of interior space of the hull is closed using a wall (3) made of closed cell semi-flexible/semi-rigid synthetic material, and is fixed to the hull using adhesive (5) i.e. polymer based elastic adhesive, to constitute the compartment, where the wall is constituted of semi-rigid /semi-flexible closed cell foam.
