Abstract

Grounding protective device for sailing vessels and similar boats provided with a fin keel to eliminate to the greatest possible extent the impact effect on a boat when the keel touches ground and to give a long braking distance in order to prevent damage to the boat and the risk of injuries to crew members. A stay is provided in the central plane of the boat which extends from at least either of the end edges of the fin keel at their lower ends to a point so located, that between the point and the fin keel the stay extends at least as deep as any part of the boat.
