I watched the vid, including the part where the “kayak” is flipped and floating upside down. The “rubber” is probably some sort of vinyl or rubberized plastic, actually. I have something similar, not quite as elongated, that holds 2x smallish adults. (It will carry a larger pair, but is then crowded.)
The guy’s wet suit(?) probably doesn’t taste much like anything a humpback whale would eat, either.
Yeah I was just goofing around with you. He’s lucky he wasn’t hurt more. Anyway, I’ve dove in wet suits and worried li looked like a seal. Never worried about whales but tigers, whites, and bulls were in my mind. We may be at the top of the food chain but we ain’t alone. In the water or on land. Be safe Regards :).
