Re the weights, a hypothetical question. Let's say I'm
singlehanding so I have to do all the hard stuff myself.
I'm assuming that the main upper body muscles worked
are your biceps, lifting, and triceps, pulling?
What's the kind of weight you'd have to be capable of
manhandling?

Though using the term "manhandling" term and so, possibly, using the
"...ing" portion including, too, in "pulling" maybe to denote on-going
physical action (though the poster doesn't actually so say), note the
apparent absence otherwise from this query of any reference to
comparative speed or to time in any other respect.

Maybe not "hypothetically": While singlehanding in stormy weather, how
much pulling and lifting for how long a period is the sailer
conditioned and able to continue to do if, say, sail changing or a
tangled reefing line or maybe torn and flogging and maybe also wet and
so very heavy sail needs attention?
