Yes, having proper and suffient air circulation in the hulls is a very good idea. After I sail, I normally don't have much water in my hulls, but i still remove the drain plugs just to dry them out a bit. I will be installing inspection ports on my H16 just to improve the air circulation, that is the key to keeping your huls dry. Also, promptly repairing any small cracks and dings in the hulls with epoxy will prevent leakage.
