On or Off

I don't like running it the whole time I am away in case something breaks or a leak in the water line.
If I just turn it on I will leave it to cool down for a while.
But after that I am usually on the boat when it's on.
Besides, it doesn't take that long to cool down a boat, at least not my 29 footer. Some larger ones may take a bit longer.

Dont have air (old boat) I always say though, having air on a boat is like bringing your breifcase / laptop to the beach. Why bother? you are on a BOAT

It is against the rules of most marinas to leave it on and it would suck if you got a leak somewhere and it sunk the boat...

I leave it on a dehumidfy setting, keeps the cabin nice and fresh...

I leave ours on every so often if I know I'm coming down again and its hot. Other than that there is no reason to. The boat cools down in a half hour or less anyways, even on the hottest days. If your boat doesn't leak you shouldn't have humidity issues. And on the issue of something leaking or breaking while your away I don't think that matters either. The a/c system has its own seacock which is always open. If you spring a leak in the system the boats going to flood/sink anyways. The pump being on will only expedite the process. If your paranoid about something like that happening then you better get in the habit of closing ALL of your seacocks while your away.

We turn our AC off when we are gone. Too much could go wrong!

I am not a early morning riser. When I want to sleep in till noon in August on the boat I need the A/C going.

I don't leave anything unnecessary on while we're not there. I figure why risk what could go wrong, and why waste finite service life hours during time when I am not there to enjoy.
