We've always hauled out every year, with one exception when I waited too long and the yard was full. The mast has never been down before, though. Probably because I feel really uncertain about how the heck to go about it, especially the interchange between me and the yard crew. Ours is a really, really self-service yard, so I don't think I'd trust the yard crew to be in charge of this. If I'm in charge, I guess I'd have to figure out exactly what to do in advance. For one thing, I have 4 cables going up the mast. Ours is deck-stepped, so the wires do appear briefly at the bottom of the mast before disappearing into a chrome fitting down into the cabin. Do they typically have disconnects built in? I haven't looked yet. I think there's a teak block on the cabin ceiling that would reveal the answer. If they don't disconnect, how the heck do you deal with them?
Anyway, I don't expect you to supply all the answers: just thinking through the long list of things I don't understand... Thanks for your comments, Dave!
