Abstract

Abstract This disclosure relates to a removable portage handle for canoes. A first transverse member is removably secured to the bow/stern of the canoe by adjustable clamps. The handle member is pivotably secured to the first transverse member. A second transverse member is secured to the handle member and removably secured to the canoe. The handle member is adapted to be generally horizontal by including an obtuse angle. The obtuse angle is reinforced as by a truss. Further weight transfer is provided for in the form of a hook member secured to a belt which may be worn by a canoeist on the shoulder, around the waist, or both. The hook member is adapted to mate with and engage a hook receptacle secured to the handle member.
