Audi recently helped develop the Trimaran Yacht with the help of Stefanie Behringer – a german grad student.
In the words of designer Stefanie Behringer:
The new concept integrates two jet skis within a motorboat. the hull’s architecture is based on a trimaran (a boat with multiple hulls), consisting of a main center hull which is supported by two smaller outrigger hulls on either side of the boat. Inside each of these two outrigger pods, one jet ski is stored.
The main advantage of multi-hulls, is their slender shape which makes them efficient, resulting in less friction resistance in the water. Furthermore multi-hulls are very stable at sail and at anchor.
the boat is driven by two efficient and lightweight AUDI TDI (turbo-charged injection) diesel engines, while the jet skis are electric driven. at low speed up to 8 knots, for example in bays or harbors, the whole boat can be moved with the single power of the electric driven jet skis, without producing any emissions or noise. at higher speeds of up to 30 knots, the two diesel engines can be switched on continuously. during this process the electric supports the diesel engines while accelerating, so that the boat is planes at a faster speed and less fuel is needed. at the same time the diesel engines recharge the batteries of the two jet boats.
The boat’s overall length is 15m, and due to its slender center hull measures only 6.40 m wide. The jet driven concept allows one to even travel in shallow water, because its draft is only 58 cm. On deck there is space for 12 people, while below, the boat offers more room in the form of four berths. By flipping down a saloon table within one of the spaces, another two additional berths can be offered.
