Of course - that makes sense. Thanks for clearing that up.
I'll have to look into it more.

Mark,
You won't have dynamic falls (one would hope) when climbing the mast. Dynamic
falls happen when you are climbing and leading (the lead regularly is above the
least piton or nut and if you fall you drop the double that distance). When you
are climbing the mast, all your falls would be static - if you main gear fails,
you would simply hang on the safety line. If you have someone helping, that
person would take the slack of the safety line. If you are solo, you would move
your attachment point (the Prusik's knot; the 3rd ascender) up as you are
climbing. The safety line (and attachment should be almost tight (not too
tight, you want the freedom of movement).
So in short - leave the dynamic ropes to the climbers; use the static ropes
(lines) that we all have on the mast.
Unless you are climbing the mast on a regular basis. You should not damage the
halyard. There are different kinds of ascenders (like there are different kinds
of clutches); some are gentle on the rope, others not so much. However, most of
the ascenders are designed to be used regularly on the rope, so they should not
make any significant damage to the halyard.
One other thing, if you never tried it before, train for it like with anything
else. I would not suggest that the trip straight to the top of the mast is the
best thing to do on the first try. And if you try it first, think not only how
you are going to go up, but also how you are planning to come down (the latter
might be more tricky).
Good luck
Marek

I've been reading this discussion with some interest - while I have sent one
kid up the mast I don't expect my 14 yr old to manage more complex tasks.
I know about using dynamic ropes for climbing - but how do you get the dynamic
rope up the mast to act as a safety line? And what line are you climbing?
Should I be concerned about wear on my halyards using ascenders (with I believe
geared pinch mechanisms)?
For a safely line I know I could use a dynamic rope tied to a halyard and
hauled up to the top of the mast - but it seems that extra knot brings another
failure point we'd prefer to avoid.
Plus - if you are climbing alone (nobody is taking up the slack in the safety
rope) - then I'd guess you need a 3rd ascender for the safety line.
If things go wrong how to you lower yourself with that safety line?
Guess I should read up more on ascenders!

All,
I have been following this discussion with interest since I just
returned to my southern project boat with a so-far unused ATN Top Climber, and
intend to use it in the next couple of days. I have taken note in particular to
the idea of using a loop(s) to stay at the mast. The designer of the device
however, has at least in the past, suggested securing the static line away from
the mast because it makes the climb easier. I have not tried it either way, but
I like the sound of staying at the mast better. Anyone have comments on this
aspect of using the ATN climbing gear? Obviously the boat would have to be
pretty steady.
On a separate note regarding fall arrest. I had a conversation one time with an
accomplished ice climber and asked him what type of line he preferred, nylon or
low stretch. He seemed to think that I was a complete idiot for even asking the
question, and maybe I was. Anyway, just to save anyone else who has not thought
it through from similar embarrassment or injury, you definitely want any line
that might arrest a fall to be stretchy. Nylon in other words.
I plan therefore to use polyester for the static line, and nylon for any safety
fall arrest lines.

Working on a topping lift in the Gulf Stream. If you are climbing underway,
MAKE SURE you have a loop to hold you near the mast. It does not look rough in
that photo, but the swells at 55 feet up were enough to make it hard to hang
on, and if you get loose you will hit one or more things pretty hard.

I use the same ascenders with my own concoction of straps but unlike the fellow in
the “atninc" ad I prefer a bosun’s chair to a climbing harness. Plenty of
pockets for tools and your vitals don’t go numb. These allow you to actually climb
above the top of the mast so you can work readily on mast top fittings.

Ryan — many on the list prefer a standard climbing harness and
ascenders for this type of job. I personally prefer to sit while

I’ve had very good luck with this equipment; in a previous life as a marine
electronics installer, I spent a LOT of time up masts, and always felt safe and
comfortable.
YMMV…
