We discovered the Torqeedo engine whilst searching for an efficient engine for our solar boat in development. The problem with solar boating is that you need to develop good speed without using much power. That is why we use the Torqeedo engines on our boats. Here we'd like to introduce you to one that we have almost finished building and another at the early development stage.

This boat is built as a family camping boat. The sort of boat for a bit of fun on the river teasing the fuel guzzlers! But there is also another purpose: to be able to do a long passage non-stop, like the Brisbane-to-Sydney run. By doing so maybe we can convert a few people to clean motoring…

The Delta 6 is a  6m power trimaran designed by Tony Grainger and built by Noosa Marine. The goal is to build a boat capable of cruising at reasonable speed using very little power.  We have been able to achieve 5 knots on 1000 w of power usage (500w per motor).  We feel that with some optimisation we will have better results still.....
