Abstract
A rudder position return device for a boat rudder of the kick-up type comprises a U-shaped clip with lateral lugs, an elastic band to be stretched across the aft side of the rudder and be fastened to the clip at its fore side and a pair of dish-shaped washers to fasten on each side of the rudder above the band to act as stops for the band when the rudder is in a fully kicked-up position.
