Sizing varies with the climate. I have 10K on a 34' catamaran
on the Chesapeake, and a little more would be nice. So I would say 10K is about right for you, with a smaller boat in cooler water
Also consider available space and power. If you stay under 12K you can probably run on a spare 20a breaker, simplifying installation
. You may also have shore power
limitations. These are the reasons I went with 10K, and I am satisfied; no point in having something you can't easily power.
A heat pump makes no sense in a northern climate IMHO. As soon as there is frost you have to winterized and it is done. Can't run it again until the water
is above 40F, to avoid icing. In other words, unless you are in FL or CA, it only works when you don't needed. Get a fuel
