Why does the Marstrom 20 keep the same rating with curved blades?
(they would have gone back to their straight blades if it was slower?)
Legitimate point but a similar point can be made regarding the F18, F16 and N20. Both the F16 and F18 have had major changes with daggerboard design. The N20 has gone to an open sail plan and totally different mast. The only class that can point fingers and bitch about numbers is the H16 IMO.
There really is no point in complaining about DPN numbers when there is absolutely no way to address the issue (see previous post). Yes I have approached the DPN committee with a request to review the numbers and a method to do it but unfortunately it was a non starter. So... until the DPN committee is willing to think outside the box DPN is what it is. And again, we always have the option to use SCHRS and/or Texel, Sailwave supports both systems.
