摘要： A fin suitable for a surf board, dinghy or wind sailing board or the like is formed of a resiliently flexible material such as a solid urethane and reinforced with a stiffening insert (11) which incorporates means (16, 17, 18) for attachment to the surf board or the like.
Interconnection of the fin with the reinforcing stiffener (11) is provided by means of openings (30 to 33) in the stiffener (11) to which the fin material extends, and projections (34,35) extending from the side wall of the stiffener (11) which are exposed by the fin material and lie flush with its surface.
A substantial trailing edge portion (24) and the tip (28) of the fin are unsupported by the stiffener (11) so that these can flex to reduce vortices in use and potential damage which might be caused upon impact of the fin against a solid object or another person.
