Thanks for all the information you have provided on this Gail. While some of us still have some questions, we appreciate that you keep us so well informed. But what is this suggestion that we may not be allowed to use the new blades at the NAs? This doesn't make any sense to me at all.... 1. Why is a class officer speculating that people who have purchased rudders from Vanguard (who say they are legal) and that comply with the class rules as currently written may not be allowed to use those rudders in the North Americans? 2. Of course the published rules fully stand. And they say that any rudder supplied by the manufacturer that complies with the measurement diagram (evn if it has been modified in ways allowed by the rule) is legal. I suppose a restriction on not using the new rudders could be written into the NOR or SIs. Is it really the intention of the class or Lewes YC to impose such a restriction? Those of us contemplating buying a new rudder - and the folks who already have one - need some clarity on this please.
