Well it's not a riptide but I'm hoping the price tag is also not the same!!! And 4mph in the water 💦💧 would be a causionary situation in a river with any kind of current!!! But still I really do like the little critter!!! But you failed to divulge the $damage's$ ??? Also can they also come with A.C. and heated sealed cabin???? Maybe even prop's for a little more auquatic speed???? I suppose you've surmised by now I'm interested😅???? And maybe even a motorcycle engine for a few more ponies 🤔🧐🙂😏????
