The ATN Mastclimber (formerly ATN Topclimber) is simple, easy, and safe! If going up the mast is a scary proposition, try this bosun’s chair from ATN. Includes a bosun’s chair with back rest and one-way jammer and leg straps with foot loops and one-way jammer.
The ATN Mastclimber received a Recommended rating for Mast-Climbing Devices from Practical Sailor - June 2010. The Mastclimber received good marks for construction, hardware, tool bag, and extras. "Because it [ATN Mastclimber] permits solo ascents and still allows a rigid perch for the derriere, many riggers like this device...Bottom Line: Earning a PS Recommended rating, this ruggedly constructed chair/ascender is the only one in the comparison that is set up for going aloft alone" ("Go Aloft Safely: Ups and Downs of Bosun Chairs." Practical Sailor Vol. 36 No. 6, p. 8-13).
Hoist yourself safely and quickly up the mast using only leg muscles even when the boat is heeled. Stand up on the two leg straps, slide up the one-way jammer of the chair seat, sit down, and slide up the one-way jammer of the leg strap. Repeat until the desired height is reached. Reverse the procedure to descend the mast.
The ATN Mast Climber uses anodized aluminum and stainless steel mast ascenders that fit OVER a taught 3/8" - 5/8" halyard line. No need for knots, static lines, or unattaching shackles. Simply fit over the line, twist, and secure with the pin. From start to finish, the Mastclimber makes ascending the mast easier than ever and you can do it alone!
