The next stage in the building process was the lamination and installation of the stem. The stem piece was laminated from two 100x100 mm Meranti (Lauan, Philippine Mahogany) planks. That was the easy part! Next the stem had to be set up on center line and at the proper angle and distance from bulkhead A. The backbone then had to be connected. All had to come together so that the waterline, center line and final planking dimensions agreed to the plan scantling. The stem and backbone were then glued in position complete with knee. The backbone and transom were also connected with a knee. The knees where constructed out of 4 layers of 12 mm plywood. The stem was then planed to its final shape. This was done using temporary stringers as guidelines. The stem took 36 man-hours. In total I have spent 527 man-hours up to this stage.
