Re: Under 18' Which is best fiberglass hull or aluminum hull?
I just went through this decision - glass tin or rubber.
If you use your boat for camping (beaching), exploring (beaching), fishing, hate maintenance, have a smallish tow vehicle, don't need to show off a fancy boat, get it full of dirt and sand, then tin all the way.
If you like to cruise, go from dock to dock, like to impress folks with a pretty boat, drink cocktails in the marina, have a V8 tow vehicle then glass all the way.
If you like to get wet and are into diving and patching your boat on weekends, then rubber all the way.
