ATN "TOPCLIMBER" - maintain and check aloft all the standing rigging of your sailboat.
The Topclimber will allow you to get up your mast safely, quickly, using your leg muscles, without any outside help, even when the boat heels. The ATN Topclimber is the only bosun chair that allows the operator to work ABOVE the mast head without leaving the chair.

Features:

• Minimal set-up time
• Rugged and simple construction ensures years of use
• Uses the leg muscles to climb, allowing you to reach the mast head not exhausted by the climb, and since it rides onto a static line, taut between the deck and the mast head, it prevents you from swaying away from the mast, helplessly, even if the boat heels over

Specifications:

• Consists of 2 parts:
  • a bos'n's chair with back rest and one-way jammer
  • leg straps, with loops for the feet, with one-way jammer
  • Rides a 7/16" to 1/2" low-stretch line (static line)
    • Use a piece of line dedicated for the ATN Topclimber, longer than the mast is tall, + 10' to reach a winch.
    • Top end of the static line - bowline it through the spliced eye of the halyard: bypass the snapshackle, not only for safety reasons, but also to gain a couple of inches where you'll need it most, at the masthead.
    • Deck end of the static line - feed it through a snatch block, at a stanchion base on the rail for example , and then onto a winch: you'll find that the static line is best tight and stiff, and that it is better to be at an angle going up, away from the mast, which explains why it is better to fasten the snatchblock away from the mast step...

Operation of the ATN Topclimber is done by alternatively standing up on the leg straps, which allows you to slide up the one-way jammer of the bos'n's chair, then sitting onto the bos'n'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.

NOTE:
Some of the ATN Topclimbers do not have the "spacer strap." ATN has tried it both with and without the spacer strap and the general feeling was that while looking OK, the spacer strap didn't add anything to the handling of the ATN Topclimber and that without it, it was simpler to rig and operate.

The ATN Topclimber is our best selling bosun's chair due to its ease of use and great features. It makes working on the top of your mast a breeze.
