ATN MastClimber: Climbing the mast has never been easier or safer!
ATN MastClimber
The ATN MastClimber is the only single handed bosun's chair that allows the operator to work ABOVE the mast head without leaving the chair. The MastClimber makes climbing the mast safer and easier. The MastClimber does not require a static line as it can be fit OVER any existing halyard.
The Operation
The MastClimber is a great system as it uses the leg muscles to climb, allowing you to reach the mast head not exhausted by the climb. Operation of the MastClimber for climbing the mast is done by alternatively standing up on the leg straps, which allows you to slide up the one-way jammer of the bosun's chair, then sitting onto the bosun's chair, which allows you to slide up the one-way jammer of the leg strap, then standing up on the leg straps. To descend the mast, the procedure is reversed.
The MastClimber consists of 2 parts; a bosun's chair with back rest and one-way jammer, and leg straps (with loops for the feet) with one-way jammer.
Also available is the ATN MastClimber Kit which excludes the bosun’s chair - the option should the sailor wish to keep their favourite bosun’s chair. The MastClimber Kit includes 2 Ascenders + Footstrap + Upper Extension with a bag.
