Hanse Yachts introduces E-Motion Rudder Drive – an interesting propulsion type, with a special folding propeller….
An electric engine and a folding propeller have been installed into the rudder shaft, replacing the combination of diesel engine and sail drive. As a result, the propeller thrust is in line with the rudder position. This enables turning in the smallest circles or rotating around your own keel; it could be a perfect solution for maneuvering in narrow ports.
Making 4.5 knots with calm seas, the new Hanse 315 equipped with four lithium-ion batteries has a range of up to to 30 nautical miles – enough for all European inland waters and many coastal waters. At lower speeds, the range is significantly increased. The Rudder Drive can also be used with two batteries if a shorter range is required. The maximum speed is 6.1 knots – nearing the maximum speed of the diesel version.
The quiet Rudder Drive is also lightweight: 100 kg less than the diesel saildrive option. The Rudder Drive does not require a hole through the hull, lowering the resistance while sailing. The electric drive’s simplicity means less maintenance, as well.

From a standstill position, the yacht immediately starts to turn without having to pick up speed first. In addition, you enjoy all benefits of an electric engine. It will be the future?
