another vote for aluminum for the already mentioned reasons, also they take the weather better if stored outside, takes a smaller hp motor vs the same size fiberglass, more fuel efficient. Older fiberglass boats especially scare me, make sure you check them over good especially around the transom. Look for cracks, or any swelled areas, check the gel coat for chips that may have let water in and soaked the wood core. Good luck with your search. Older aluminum boats may have cracks or loose rivets too so take your time and look them over well too.
