Hanse Yachts AG introduced the 315 e-motion rudder drive, which the German company said was developed in cooperation with partners Jefa and Torqeedo.

The company said the new drive has an electric engine that not only replaces the diesel engine and its components, but also the complete sail drive.

A 4-kW electric engine and a folding propeller have been integrated into the rudder shaft. The company said the system’s advantage is significantly improved maneuverability, as well as emission-free and almost silent propulsion.

The integrated engine in the rudder directs the thrust in the respective direction of the rudder. The company said the extended rudder angle of 100 degrees in total allows the Hanse 315 with e-motion rudder drive to turn from standstill on her own axis, forward and backward.

When a boater is docking or taking off parallel to the pier, the stern of the yacht can be pulled precisely to the dock, which the company said is particularly advantageous in strong winds and narrow ports.

The system consists of two to four lithium-ion batteries, which the company said propel the yacht at smooth sea and at 4.5 knots as far as 30 nautical miles. At lower speeds, the range is extended significantly; the maximum speed is 6.1 knots — not much less than with the conventional diesel engine, the company said.

The Hanse 315 e-motion rudder drive will have its world premiere at 2 p.m. on Oct. 30 at the Hamburg International Boat Show.
