Easy to set up; requires only a twist of the telescoping tubes to lock in position. Hook will not mar boat's finish. Curved surface for fending off lines and stanchions. Ribbed hook for extra strength. Orange vinyl tip for fending off. Bright color improves visibility and eye/hand coordination. Guaranteed unbreakable hook made of non-corrosive Lexan (tougher than brittle metal alloys). Thick, heavy duty neck and body.
