The dot in the bay above is Perttu’s Microcruiser sailboat on a three day trip on the extensive Finnish waterways. The boat is tiny – 8ft long and is based on my successful OzRacer design (formerly OZ PDRacer) It is a brilliant concept and sails well upwind and down on inland waters.
A new plan specifically for an electric trolling motor. 5 to 6mph from a 34lb thrust Minn Kota. This is a purpose designed low power boat for daytrips and fishing. The plans are $30 and many will be able to build the boat for less than $200.
