OK, my apologies to all. I’ve been pretty much MIA for the last several months due to an unbelievably busy schedule. Still pretty busy but managing to get some office time in to share some of the things I run into . This announcement from Torqueedo and Hanse came in just this morning and it is showing a really cool (in my opinion) new concept in E-propulsion. Check out the rudder on this concept drawing. That’s a folding blade propeller integrated into the rudder. Read the press release below to find out more. I can’t wait to try this out!




The new Hanse 315 e-motion incorporates the ground-breaking, Torqeedo-powered Rudder Drive. Replacing a traditional inboard engine, the optional lightweight propulsion system is integral to the rudder, providing superior maneuverability and power generation while underway, without the noise and fumes of a diesel.

The Rudder Drive was developed by Torqeedo in concert with Hanse Yachts and rudder manufacturer Jefa Marine. The core of this innovative concept is the proven Torqeedo Cruise 4.0. Part of the foil blade itself, the streamlined system replaces a conventional driveline or sail drive inboard diesel.

Due to the placement of the 4 kW/8 hp equivalent Cruise 4.0, the rudder blade applies efficient, directional thrust through a 100 degree range. Precise maneuvering is accomplished without the need for a bow and/or stern thruster. The Hanse 315 with Rudder Drive easily spins on its own axis, both in forward and reverse. While docking, the stern is quickly brought into position—a desirable trait on a breezy day or when entering a narrow slip.

Making 4.5 kts with calm seas, the emission-free version of the Hanse 315 equipped with four lithium-ion batteries has a range of up to 30 nm. At lower speeds, that distance is significantly increased. The maximum speed of 6.1 kts nears that of a diesel engine. It will charge in just three hours, either at the dock or while sailing—the folding propeller will actually generate power.

Weighing 220 lbs. less than the diesel sail drive option, the Rudder Drive doesn’t require a thru-hull, reducing drag. Its simplicity means less maintenance as well. A video of the unique Torqeedo-powered Rudder Drive on the Hanse 315 e-motion is at
