摘要
It concerns an attached ballast 12 whose submerged surface 10, inscribed within a curvilinear tetrahedron 100, constitutes an anti-drift plane and a grounding sole plate. It comprises a forward bossing 11 embedded into the hull Q allowing a leading edge 10A to be formed at a small incidence angle i. When grounding, its median width 10L makes the ship self-stable; its median thickness 10H protecting the hull plating by unbroken ground clearance. Its trailing edge 10F protects the propeller H and produces a draught compatible with a fixed rudder blade S. It can include a vertical slot 3 equipped with a shaft 2 and rebates 4 allowing a removable centreboard 1 to be fitted. An appendage according to the invention, easily adaptable to the majority of moulded-hull sailing boats, increases the life span as well as improving balance under sail. IMAGE
