Document Type and Number:
WIPO Patent Application WO/2009/113041
Kind Code:
A3
Abstract:
An unsinkable sailboat comprises a hull (2) with a keel made from a relatively rigid material and a pair of lateral sides (5, 6) with respective lower portions (5', 6') and upper portions (5', 6') or topsides. Each of the sides (5, 6) has a flotation member (7) of lower density than water which at least partially defines the corresponding upper portion (5', 6') to act as a reserve of buoyancy for the hull (2) and at least partially prevent it from sinking even when there is water therein.
