Abstract

Abstract A footloop for a windsurfing board having a deck with a top surface. The footloop is formed of a strap having opposite ends attached at the ends to the top surface of the board, including a device for attaching at least one of the ends to the deck which includes a releaseable mechanism for holding an end portion of the strap until a certain amount of force is exerted on the strap, whereupon the strap is released. The releaseable mechanism is adjustable for differing amounts of force and includes a fixed member permanently affixed to the board, a moveable member co-acting with the fixed member for holding the end portion of the strap and an adjustable device for locking the moveable member relative to the fixed member until the certain amount of force is exerted on the strap.
