Bouyancy chambers...??

Yeah, see unlike foam core plastic, composites (fiberglass, Kevlar,
carbon fiber) don't float very well. If you don't want your Wildfire to
go to the bottom if you flip it, you build a chamber that holds a couple
of gallons of air into the bow and stern. This means that if you had
another boat that was a foot shorter and six inches narrower, it
wouldn't fit inside.

Yeah, i know the boat is dirty.
