For this project, a 70ft aluminium sailing ketch was re-powered from diesel to fully battery electric. First the original 800 kg Diesel engine was drained, disconnected and removed. This freed a large amount of space for the new 20 kg electric motor and some of the batteries.
A particular challenge on this vessel was the placement of the batteries, as no major modifications of the interior was desired, which called for creative placement of the battery modules. In all 32 7.2 kWh modules were installed for a combined capacity of over 230 kWh.
