Bart,

FOR WHAT ITS WORTH; In my old age, I've rediscovered the extension
ladder for going up the mast!

With my age and Neurologic disorder (MG) I can't go up and I can't winch
a crew up. I can set a ladder up, using a halyard. I crew going aloft
still wears a Bosun seat and a halyard but they can climb and tie
themselves off. I only have to take up the slack on a self tailing
winch. The crew works more comfortable from the tied off ladder and
secured bosun seat.
