This here is a, uh, "soft boat." It's basically a sofa on a floating platform with a motor, and it costs $16,000. It's controlled by a joystick and comes with a fridge on board if you can't go 15 minutes without a drink.
It appears to be designed for allowing people on big, fancy yachts to travel short distances to other people's big, fancy yachts. But hey, at least it's eco-friendly! It's purely electric, so it's zero-emission, which is nice. I guess.
