Hull - Bodyplan
The first thinng to do after copying the bodyplan to the right size was making the keel and the ribs and making a building plank. The ribs are made out of 5 mm plywood and the space between each rib is 20 mm. This space will be filled with XPS plates which will be sanded down to the shape of the hull.
The ribs are glueed to the keel.
