Rick - "You have not provided any actual drag numbers. The Savitsky information is too general to apply to my hulls."
What were you trying to say with the Savitsky PDF then? As far as I can tell the Savitsky information is in total agreement with everything I have been saying.
The actual drag numbers depend on the hull shape. How could I possibly provide actual drag numbers on a design that has never been built, nor do I have the specs for?
That is your answer to the general observation that hard chines create more drag at displacement speeds? And that a concave stern section creates more drag than a straight or slightly convex stern section?
