Boat prices are utterly insane right now wit no end in sight to escalating prices. It's a terrible time to be in the market for a used boat. It's interesting that down on the Gulf Coast, you don't see aluminum boats offshore. In the PNW and AK, there are more aluminum than fiberglass. I prefer fiberglass. It's quieter. In the summer it's cooler and in the winter it's warmer.
Aluminum seems to hold up better when you hit the rocks, and when the water is froze warmer doesn't matter.
