This is something of a theory question. I have been designing a boat and reading all I can find on kayak design. I came across a article by John Winters (greenval.com) that states that one years scratches and dings can easily transform the coefficient of friction in an composite canoe so that the frictional resistance doubles.I.E., a boat that the drag program predicts will have 2.5 pds of resistance at 3.5 knots, will then have 5 pds of resistence at that speed.
If it were not for Winters reputation I would not believe it. Actually I am not sure I do, but it sounds like the best argument I have heard for stripers since they are easy to refinish.
How reasonable is it to infer that if one did an extraordinary job of fairing (wood and particularily the final cloth and epoxy coat) that you might have a 10% + gain in efficiency over an ordinary good job? If you think I am all wet, please tell me as it may save me a lot of work. Thanks
