Abstract: A sail banding device for preventing a furled sail, in particular a spinnaker, from filling until the sail is fully hoisted. The sail banding device includes a pair of flexible elongate anchor straps coupled together. The anchor straps each have a plurality of flexible binding straps coupled thereto. Each of the binding straps is looped around the associated anchor strap in a generally U-shaped configuration such that the ends of each binding strap outwardly extends in a generally common direction from the associated anchor strap. The ends of each binding strap is detachably attached together.
