Few boat manufacturers can accurately say they’re “legendary,” but Boston Whaler can certainly make the claim. Ever since they sawed one of their 13-footers in half and proved the bow and stern would still float when separated, Boston Whaler has been known for building a line of “un-sinkable” boats. But just sawing one in half wasn’t enough: they’ve also blasted them with machine guns, parked dump trucks on their overturned hulls, and driven them up whitewater rapids. Yes, they keep on floating. What's the secret to becoming a legend? Boston Whaler pours closed-cell foam between an inner and outer layer of fiberglass, until all the voids are filled. When the foam hardens it bonds the fiberglass pieces to each other, creating a one-piece hull structure that’s far tougher than the average pleasure boat. Net result? You can pull the drain plugs, load on weight, cut one in half, whatever you’d like—these boats just won’t quit floating.
