Trailerable water ballasted sailboat |
摘要 |
In the trailerable sailboat disclosed herein, the provision of water ballasting enables the use of a V-bottomed displacement hull shape with substantial deadrise yielding a low-wetted surface are in relation to effective displacement. The water ballasting is provided by sealed structural elements which form, with the hull shell, a ballast tank space which is essentially entirely below the design waterline of the hull shape so as to permit self-filling of the tank space with seawater.
