Builders often think they know better than the designer. I've tried to resist this temptation and so far have always found that Matt's methods are the best. Nevertheless, I thought I'd try and alternate method of creating the chine runner. Instead of laminating and shaping them in place, I thought I'd rough out the chine runners to shape off the boat. No holes needed in the hull, but not as efficient use of wood.
Here is the laminated stock I cut them from.
And the runner cores roughed to shape.
And laminated to the hull.
Final shaping/fairing of the cores and covering with 3 layers of frp with more fairing, still to be done.
