Transcript: An unsinkable boat. Creature Craft created an inflatable whitewater raft that won’t flip. The craft is purposely designed to tackle big powerful rapids, with the ability to self-right when flipped. Its multiple chambers are what prevent it from sinking. The boat is made out of PVC fabric with a protective coating. Some models can be fitted with a motor. Creature Craft’s whitewater rafts start at $4,995.
