These are some very creative jet pumps. This is even the firs time that I've ever heard of something like this. It seems like a device used to keep afloat and move fast on the beach. I'd love to get my hands on something like this, because I always loved to float on the sea. This would probably cost a fortune, so I can only dream about it for now. I'll try to research more about these things, if ever I find more interest in them in the future.
