I was keen to start the moulded ply section of the hull because I was concerned that my 6mm plywood might be too stiff for the task. Dudley recommends 3 ply while mine is 5 ply hardwood and quite a bit stiffer. After a bit of experimentation I settled for clamping the 6 mm ply to the doublers using 12 mm ply clamps secured with large self tappers. The hull side of the 12 mm ply clamps is covered with packaging tape so that it will not stick to the hull.

I also made up a very precise 788 mm radius template to check all the doubler angles and stringer contact points. Because the stern where I started the radius chine ply has a very flat run great care is needed to keep the run straight.

The neighbour watched the progress all through the day at as evening fell he gave it a nod of approval.
