Can anybody recommend the SIMPLEST chine sailboat software that gives developable plates. I have tried most of the programs in the non-pro area, and none of them will do this easily. I want to input a number of sections values of a chine longkeel form with overhanging counter, and fair these three lines, then check if the form is developable. The three lines are the inner deck edge, inner chine line and the inner rabbet line assuming a constant thickness keel. None of the programs fair properly, ie can be forced to fit at the bow and stern, and "float" fair between the other points.
