If you're on Rattlesnake Island, an aluminum boat can be pulled up on shore—a big plus. Like the Whaler, they're also unsinkable.
Charities often have them donated for their yard sales, so in addition to being no-maintenance, indestructible, unsinkable
and inexpensive, that purchase can benefit the community as well.
My neighbor's 14-foot Feather Craft got loose from their dock during 1991's Hurricane Bob and banged against a rocky shore for hours. It's still in leak-free use, makes the eight-mile trip to Wolfeboro on occasion, and presents itself pretty well after fifty years!
Found at the very bottom of the used-boat price range, aluminum boats built in the 40's tend towards odd styling affectations—
strong, but comparatively heavy among aluminum boats.
