The Suntory Mermaid II Boat is different from what you've seen in the market so far, since it uses waves to power it instead of a motor. This is probably the greenest nautical power source ever since the sail's introduction, where a couple of fins located side-by-side of the Mermaid II's bow are moved by the waves to produce a dolphin-like kicking propulsion movement. Too bad you're stuck with a top speed of 5 knots - that's up to three times slower than your average diesel ship. I guess grandpa won't be complaining though as he goes off into the sunset at his own pace, with grandma in tow for their second honeymoon.
