Detailed Description

ATN MASTCLIMBER
 


Attention ...

The new ATN Mastclimber no longer requires a static line as it can be fitted OVER any existing rope halyard, from 3/8" up too 5/8" !
 
 
Notice:

Some of the ATN Mastclimbers do not have the "spacer strap". We have tried it 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 Mastclimber and that without it, it was simpler to rig and operate.

 

The ATN Mastclimber is a bosun chair that allows the operator to work ABOVE the mast head without leaving the chair.

See the article in the May 2003 issue of Sailing World by Emma Richard, one of the competitors of Around Alone, going aloft to repair her main halyard , at sea, for 4 hours with the ATN Mastclimber, page 42-43.

How often did you think, "I should really check that masthead fitting, and the spreaders tips, and the halyards exits", but were stopped because of the lack of knowledgeable or willing help?

You could do it like Mr. Jim Clark, owner of the 156' cutter "Hyperion" who had a mechanical ascending crow's nest fitted onto the 199' mast, but if you are a little lite on budget or mechanical help, the best way to solve that problem is the "MASTCLIMBER".


The "MastCLIMBER" will allow you to get up your mast safely, quickly , using your leg muscles, without any outside help , even when the boat heels.
About MastClimber
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 maintain and check aloft all the standing rigging of your sailboat.
   

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, 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.

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 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, procedure is reversed.

Installation Notes
The ATN Mastclimber rides a 7/16" to 1/2" low stretch line ( Static Line ), you may be able to use your spinnaker halyard, but even if your spinnaker halyard happens to be of that dimension, since the ascenders of the ATN Mastclimber are the kind that you feed the line through (so the line cannot accidently escape) you probably won't be able to use it because of the spliced snap shakle at the end of the halyard.

Our recommendations:

  • The best thing to do is to purchase a piece of line dedicated for the ATN Mastclimber, longer than the mast is tall, + 10' to reach a winch.
  • The best thing to do with the top end of the static line is to bowline it through the spliced eye of the halyard: bypass the snapshakle , not only for safety reasons, but also to gain a couple of inches where you'll need it most, at the masthead.
  • The best thing to do at the deck end of the static line is to 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...
