Abstract (en)

[origin: WO2006123054A1] The invention relates to a fin unit (2) with elastic attachment system on an underside (1) of a marine apparatus, such as a wind surf, kite surf, fly surf, wakeboard, knee board and particularly a surfboard. The fin in the mounting thereof is partially made to self-align in the flow of liquid medium with the aim of avoiding the hydrodynamic stall caused by the passage of high turbulence and/or large lateral movements caused by the surfer in extreme motion. The possibility for self-orientation is due to three fundamental parameters which are: the type of elasticity of the attachment system (3-4-5-27), the forward position of the centre of gravity G towards the leading edge (15) and the form of the root profile (9) of the fin (2) which has a thickening (7) of the trailing edge thereof.
