An electric conversion for quiet, reliable cruising

Tarbes II

Project background

Tarbes II is a 38ft classic wooden gentleman’s launch that was refurbished by Michael Dennett Boatbuilders Ltd in Chertsey. We were involved at the beginning of the project and worked closely with the owner to ensure the right system was delivered. The owner wanted an electric propulsion system so that he would have a quiet and clean alternative to a traditional diesel engine. The owner uses the boat for day cruising on the Upper Thames and so our key consideration was to ensure there was enough energy in the battery for a day out on the river without “range- anxiety”.

Our work

The 10kW Waterworld motor combined with a substantial battery pack delivers both sufficient range and plenty of extra power for manoeuvring and emergency stops. The owner can cruise for 8 – 10 hours a day at just under the Upper Thames speed limit of 8kmh, with no concerns at all. On board the motor has been placed beneath a small dining area, the 48V battery bank is located in the rear cabin and is built into the seating area.

The result

The finished result of this diesel to Waterworld electric motor conversion is a stunningly quiet and elegant launch.
