Meet the killer whale submarine

This is the Seabreacher Y, a high performance two-man submersible sports boat.

US-based Innespace builds a series of small submarines based upon a strikingly dolphin-like fuselage.

But the latest Y model is the first to look like an Orca. The distinctive black and white paintwork obviously helps, but it also comes with a more rounded nose and larger whale tail.

And the dorsal fin is taller, with newly designed pectoral fins. The tail fin needed reshaping to allow the craft to perform a 180-degree back flip.

Mounted high in the dorsal is a forward-facing video camera for a proper back seat view.

At the rear of the craft is a 255 horsepower supercharged engine, driving the Seabreacher Y to a top speed of 55mph at the surface. It’s designed to be positively buoyant, only diving to a maximum of five feet or so using downforce under forward motion.

There’s seating for two in tandem, with riding pegs and a handlebar mounted at the rear for stunt riding on the back.

Innespace currently offers a range of speedy submarines, with the Seabreacher Y costing upwards of $100,000.
