Re: Going up the mast
ATN worked for me quite well. Also used alternate safety line to harness.
Concur w/ no one under you. I have the admiral on a winch taking up slack on the safety line. Only one burning energy is me. Flag or spinaker line for tool bag/hoist for the things that are ALWAYS forgotten :-)
Got it used at Bacons, looked like it was tried maybe once! It does take some practice but once you 'get it', it works great.
I hated the bosun's chair.
