Abstract: The invention presented herein demonstrates a boat hull and method for providing improved flotation characteristics and stackability for a boat having a high strength-to-weight ratio. The boat is constructed with a pre-formed hull with outwardly extending sides and having cellular flotation logs positioned at spaced intervals thereon whereupon with normal impact to the hull said logs will not experience cellular degradation due to their rigid encapsulation. The preferred method demonstrates a structure comprising a series of rectangular flotation logs positioned athwartship along the inside bottom of the hull. Between the logs an FRP (fiber reinforced plastic) beam is positioned to absorb and divert shock waves from the logs and to increase the strength of the hull. An FRP layer above the logs completes the encapsulation of the logs and secures them in rigid engagement with the hull. The outwardly extending sides and lack of side flotation members contribute to the compact stackability features of the hull.
