Oh, I was confused by semantics and my own lack of sleep. I see that you were comparing “built-in” power winches to winches powered by a drill. I was picturing something new and novel like the built-in flagpole halyard winches. (Man, think of the hole that would put in your mast!) Sorry, most of my sailing experience prior to this Nonsuch was long ago and on large, traditional schooners where any winch is a novelty.
I do have a powered winch on my NS33 and wouldn’t (couldn’t) sail without it. It is mounted on the left side of the cabintop, which seems to be the normal place on a Nonsuch. The switch is just below it. The winch is self-tailing, but I cannot push it by hand and watch the sail go up at the same time because the dodger obstructs my view. So I look over the dodger and operate the winch with my foot. (The single button is the same as a foot-operated anchor winch button.) It sounds awkward I suppose, but my dodger has a built-in grab rail along the aft edge so I just hold on to that while hauling the halyard. It’s kind of like leaning on a rail, watching someone else do the work.
What I don’t have is a clutch for the halyard. The other control lines all have clutches, so I’m curious if there is some reason not to have one for the halyard. And, any advice for selecting or installing one?
