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.



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.

I need to do more homework on the sizing. Too small and it won't handle the
heat load. Too big and it doesn't run enough to de-humidify. The Navigator
has four independent units. The smallest is 7000 BTU and the largest is
11,500 BTU. Multiple units would be ideal in the GB, but I am not sure
there's enough space in the engine room. We'll see.
