Thank you! I know of the Michlet code, but have not used it yet.
There is one question I wish someone could answer:
What is the reason that different sources report totally different speed-wave drag associations for seemingly similar hulls shapes?
Compare the curves you are presenting with the curves for the kayaks http://www.oneoceankayaks.com/kayakpro/kayakgrid.htm - totally different relationships. Does the sharply cut vertical stern of beach cats make the difference?
