Reply To: Pattern Madness!!! Please help :/
This could be because you are trying to make a transom with – effectively – a flat panel at the centreline. The drawings are for two flat panels on the bottom of the boat meeting at a V in the middle. There is then a tolerance for the position of the chines and centre from an imaginary base line and a maximum amount of curve in each panel. Even with max curve – I had in mind that the panels still form a slight V at the centre.
One of the problems you may have if you are trying to build a boat with max curve in the bottom panels is that the curve is compound as you go down the hull and you could have problems making your plywood follow this curve.
As an aside , The Millican boat I had years ago was max curve on the bottom and I found it very hard to sail fast and it was very wobbly downwind.
I understood that to get a decent planing hull, you would try to make the rocker (keel) as straight as you can and get the chines as straight as you could. Someone will definitely have a theory that is different to this.
