The ATN Mastclimber is the only single handed bosun’s chair that allows the operator to climb the mast UNASSISTED and work ABOVE the mast head without leaving the chair.
The new Mastclimber fits OVER any existing halyard (from 3/8” to 5/8”) eliminating the need for a separate static line The MASTCLIMBER is simple to use, its set up time is minimal, and its rugged and simple construction will ensure years of use, allowing you to check aloft and maintain all the standing rigging of your sailboat.
The MASTCLIMBER uses the leg muscles to climb, allowing you to easily reach the mast head not exhausted by the climb, and since it rides on a static halyard held taut between the deck and the mast head. It prevents you from swaying away from the mast, helplessly, even if the boat heels over.
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.
Operation of the MASTCLIMBER 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 transferring your weight onto the bosun’s chair, which allows you to bend your knees and slide up the one-way jammer of the leg strap, then standing up on the leg straps once again. To descend the mast, procedure is reversed. It’s a very simple process but the one-way jammers make it safe and “fool-proof”.
