I want one for the lake - a mere $65K for the base model...
That's pretty cool. It would be rad to see one going REAL fast... doing some crazy shit.
The shark-inspired Seabreacher X has a 260 hp, supercharged, 1500cc engine and a top speed of 50 mph (which is pretty fast on water) and 25 mph underwater. If these things catch on, I bet the "crazy shit" will come with experienced pilots; like what happened with jet-skis.
For those of us with more modest budgets I think a suitcase drone would be a fine tool to hang in the garage.
