You would be forgiven if, upon first spying the HeliCat, you thought it was a helicopter that can land on water, but it's actually 100% boat — technically it's a catamaran, hence the "cat" in the name. Designed by a Seattle man who hopes to invent the sport of "extreme wake-boarding" — more on that in a second — it's actually got a few advantages over normal boats, beyond looking like it's straight out of a Roger Moore-era Bond film.
Because of its dual hull construction, combined with the added height of the helicopter-like cabin, it can cut through waves more efficiently than most other boats. The main reason the designer thinks it's perfect for wakeboarding is because it doesn't skip a beat cruising along at 30 mph over white caps, thanks in part to the twin 90 hp outboard motors it sports.
It turns on a dime, and just about every square inch of it looks like it's a blast to drive/captain. Everything has been custom-built for the HeliCat by several different companies that specialize in fiberglass molding and hull construction, and it's virtually unsinkable.
