I looked at all the systems and absolutely decided that I would set up my own, like the "frog" thingy. Then I came across a big sale on the ATN mast climber and just bought it. I've only used in in the slip, but I did have to go up in the rain a couple of times.
Overall, I think an actual climbing harness, as depicted in the frog link above would be safer and feel more secure. I have slipped perilously far on the plastic seat of the ATN. The pins on one or more of the ascenders have come close to slipping out once. Edges on hardware tend to scrape against the mast and leave scratches, and even to fray the rope that you're depending on. One nice touch is that the carry bag clips on to the seat for use as a tool bag. But it's difficult to reach the bottom. You can really improve it by sewing a couple of pockets on the inside, and some lanyard clips for your tools.
It's not really physically demanding to use, and the frog system shouldn't be either. The first couple of times I used it, I was exhausted and my arms were cramping up like crazy - I realized that I was holding on
way too tight
. Well, I certainly didn't want to drop any of the screws and nuts up at the top there.
er... has anybody noticed on Christian Lloyd's videos, how he seems to scramble up the mast on a lark, with no ropes or gear of any kind, to snap pictures while underway? In one of the recent ones, sailing solo, he sets both headsails, the main,
and the spinnaker flying, sets the wind vane, then just pops up to the top of the mast to admire the view...:0 I don't know if I'll ever have that kind of confidence about
anything.
