I need to find a method that I can use to protect a 18-ft fiberglass
boat from UV and mildew through out the year.

Before you put the boat under it's cover, be sure to wipe the interior
surfaces with a Lysol type spray. Just spray and wipe the interior so
that the mildew will not grow. As others have pointed out, a breathable
cover is best and be sure to put in vents.
