Some more specific points:

- You should have at least one vent, powered or not, for each compartment; even if air can flow freely between the compartments. My 27' boat has a cowled vent forward, a solar exhaust vent in the head (mid-ships), and a louvered companionway hatch board.

- Moist air is less dense than dry air, so you will usually have warm, moist air high in the cabin. A solar exhaust vent at or near the highest point in the cabin will therefore be most effective at getting moisture out.

- Arranging your boat's vents so that air flows along the length of each compartment (or even the length of the entire cabin) will help to dry out moist surfaces, cushions, fabrics, et cetera. Small circulation fans will help tremendously in this respect, but take electrical power.

- Two or three people inside a small enclosed space (e.g., a boat cabin) can generate a lot of warm, moist, air (even if everyone is behaving themselves ).
