Hybrid cars have been around for a while, but one German grad student is taking the concept to the water.

A new hybrid propulsion motorboat designed by Stefanie Behringer, would reduce drag thanks to its three-hull, or trimaran, form.

A jet ski attaches to either side of the main hull, helping stabilize the boat. While the jet skis are electric-powered, the 49-foot long watercraft is also powered by two diesel engines that use Audi’s turbo-charged injection technology. Audi’s Concept Design team in Munich worked with Behringer on the project.

The motoryacht is designed to reach speeds of close to 30 knots. The boat can be operated using only the 100-horsepower jet skis for a mellow, emission-free cruise around the bay. At faster speeds, the diesel engines recharge the jet skis’ batteries.
