Re: Buying a 2001 Jeanneau Sun Odyssey and want to add AC
As noted, huge difference between ducting it around the boat and having a single vent and return. I think on a 40, you would wish you had ducting, but not an absolute. You may even wish you had more than one unit.
One key is to try to avoid having the compressor and/or air handler, if a split system, near your head while sleeping. Ask me how I know!
While we run the AC (heat too btw) at the dock, we only run it at anchorage on a very occassional basis. At anchor, wind blows through the boat, as you're always facing it. Not always the case at the dock. It really comes in handy at the dock, when doing chores or projects. Those are rare at anchorage too.
We have three units. I only run the one in the master stateroom when showering. What a difference to get out of the shower to a cool room, not just start sweating before dried from the shower. However, at night, we leave the door open and rely on the salon unit to keep us cool. Too noisey to sleep with it on.

In the harsh marine environment, something is always in need of repair. Margaritas fix everything.
