Hi Chris, If your fishing boat is in and out of
fresh water, why not try one of the waxes especially formulated for bottoms? If you do a search at one of the oneline chandleries, I'm sure you'll find one. For exterior wood trim on the same boat (?), why not try one of the protecting stains developed for outdoor deck use i.e., Cuprinol or Thompson's water seal? That will get you away from the constant mtainenance routine. Good luck!
