Electric propulsion for tenders and larger boats

On a recent visit to the Düsseldorf Boat Show I was struck by the massive expansion in electric propulsion for tenders and larger vessels.
We started using a Torqeedo to power our RIB 14 years ago and we overcame our initial range anxiety by acquiring a second battery for those rare journeys when one battery wasn’t enough. There seems to be so much more choice ow and I wondered what’s others are using? Silent, oil and smoke free tendering means that we don’t be going back to gasoline but I’m keen to know how the new electric outboards work?
Also, for those migrating from sail to power, has anyone taken the plunge and bought one of the swish new foiling runabouts that seem to be filling aisles in Düsseldorf?

Hi Simon, by coincidence, we took delivery of a Spirit 1.0 from ePropulsion yesterday which gets good reviews and has a stated 22 mile range. We can’t wait to try it out, but we haven’t sold our trusty Mariner just yet!

Hi Simon, we've had an ePropulsion Spirit 1.0 Evo for 2.5 years now. The Evo bit refers to its ability to charge from the spinning prop when towed or mounted on a bracket in the stern ( a feature we are 75% through completing. So far we are very happy. It charges slowly but satisfactorily from 12v and faster on an inverter. The furthest we have ever gone is 12nm and there was plenty of charge left at the end. Speed wise, well it replace a 2hp 2 stroke so it is quieter, less smelly, less messy and faster to boot.

Excellent feedback and amazing you m as managed 12nm. The ability to hydro-generate is very cool. One day perhaps devices like the Watt & Sea Hydrogenerator will also morph into an outboard and vice versa.
