The MastClimber is the only bosun's chair that allows the operator to work ABOVE the mast head without leaving the chair. Fast and easy to setup and simple to use. Uses the leg muscles to climb, allowing you to reach the mast head not exhausted by the ascent.
Consists of two parts: (1) A bosun's chair with back rest and one-way jammer, and (2) leg straps with loops for the feet and a second one-way jammer.
Climbing is done by alternatively standing up on the leg straps (so you slide up the one-way jammer of the bosun's chair), and then sitting onto the the bosun's chair (so you slide up the other one-way jammer), then again standing up on the leg straps.
