I don't mind heights its falling I don't like. Even then falling isn't nearly as bad as the sudden stop at the end. Gravity its not just a rule
its the law.
I'm inclined with Wheels on this one. A halyard is going to carry a load far greater than any human you would want to haul up a mast. I'd make sure that I tied in to a fixed part of the shackle and my harness or bosun chair.
Used to rock climb so I was always going up the mast. When I was younger I shimmied up the mast to retrieve a halyard during a race
on SF Bay
. It was only an etchells but we needed the halyard. Skipper
said keep your legs wrapped around the mast and you can't get too hurt. Never found out if he was right b/c I never fell.
Worst time up the mast was when someone didn't latch the mainhalyard shackle properly. The main fell about five feet and the halyard stayed up at the top. Can't stop racing
can you. It was on an IOR Farr 40 (the one ton type not the One design). Anyway I went up on the second jib
halyard (Oh yeah did I tell you it was a 3/4 fractional rig) then I climbed up the diamond stay. which meant the halyard had to be lossened as I went up past the jib
halyard. The key was to keep the boat going up wind
and well heeled over. You can almost walk up the mast then. I got the halyard and refastedned the main. They dumped the main to haul up the lost
five feet. They could have waited till I got down. I didn't think about how stupid it was till I started reading this thread.
As far as safety goes a short lanyard say 5 or 6 feet with a timber hitch around the mast cinched tight and then fastened to the bosun chair would stop your fall. At least by the spreaders.
