Tensioning edge of sail - involves eccentrically mounted rotatable disc with circumferential

摘要

The sailing rig of a surfboard has a mast with its lower end (15) mounted on a connecting piece (1) which can pivot about the vertical axis on the supporting foot. The edge of the sail (12) is tensioned by means of a rope (11) which is wound around a rotatable disc which has a circumferential groove to receive the rope. The disc is eccentrically mounted on a shaft (5) and can be rotated by an attached arm (4) so that the sail edge can be tensioned very rapidly. USE - Sailing rig for surf board.
