We decided on a 16,000 for the main salon and 7,000 for the aft. We are now figuring what we need for vents, etc. The boat came w/ a portable ac, which will come in handy while we do the installation.

I have a 51'' offshore (low freeboard and interior volume) aft cockpit boat. It is cooled by two units. 16,000 btu''s handles the forward 2/3rds of the boat and 9,000 btu''s handles the aft third. On a hot sunny day, the units will often run almost continuously to drop the inside temp 10 degrees. Given the fact that my boat is a "small" fifty footer, it probably doesn''t have much more interior volume than your 42'' center cockpit. 22,000 btu''s sounds like it may be marginal in a warm climate.

Marine Air Systens have a good tutorial at:
Rule of thumb for sizing powerboat A/C:
14 BTUH/Cu. Ft. Below Decks
17 BTUH/Cu. Ft. Above Decks
I use 15 BTUH/Cu. Ft. for sailboats.
You may want to consider "reverse-Cycle" heating as well.

We have a 42 ft. center cockpit. We are thinking of installing a 10,000 btu unit in the aft cabin and galley and a 12,000 btu unit in the main cabin and v-berth. We live in the gulf coast of Texas. Any suggestions?
