I assume you will get reverse cycle A/C that can also heat? It's a
nice thing on chilly mornings.


Yes, they're nice units. I think the marginal cost over a
straight A/C is so marginal that there's no reason not to
have one. One word of caution... when you chose a unit, even
if you're hiring the installation out, read the manual
carefully. A lot of times basic installation is not kosher
and the unit won't work as well or will have problems.

Yup. CruiseAir or similar. I'd like to get one unit that is big enough to
handle the cabin, aft stateroom and V berth area. I was thinking that maybe
6" supply ducts could be used with dampers to adjust individual air flow
rates. The larger return would obviously be in the main cabin. Might have
to give up one of the drawers under a seat for it. I am thinking a
13,500 -15000 BTU would do it, but not sure. We will also have to add a
second, 30 amp service I think.


If you're planning to use the boat anywhere south of
Virginia or so, 15k ain't big enough. And we run a 28k'er on
30 amps so you can think bigger... within limits of course....

If I were going with a new installation on a boat 35' or
bigger, I'd strongly consider one of the chilled water
circulation systems. They can be very efficient and you can
put small heat exchangers & fans in lots of places
throughout the boat. Less bulky & easier to regulate than 6"
ducting w/ dampers.
