Normally AC is a summertime problem at most. It's not 365 days a year, even if you live aboard full time.

The Florida I live in frequently has days all "winter" that get into the 80's.

In a canal, or in a marina wall to wall there is little air movement , so even a full sized sun cover with side curtains is little help, thank GOD for the power hose.

Anchored out air cond would probably be required all daylight.

One concept frequently overlooked is to water cool the boat exterior.

As the boat will be sealed up for air cond , creating a good water flow on the exterior will be no bother.A small pump, a lawn sprayer should keep the exterior at local water temperature , instead of what ever the paint rises to in sunshine , perhaps 30F higher.

In the Carib , even tho we had suncovers and a well insulated hull, buttoning up for 15 min in the late PM and douching with pails of sea water was fast and worthwhile for sleeping comfort.
