The current ISAF policy is to gradually make Olimpic sailing more TV/spectator friendly. That was the reason for adopting the 49er, for requesting the Tornado modifications and (right or wrong) for the new scoring system. I wonder when they will replace the Finn by foiled Moths for the same reason.
Anyway, the current policy makes olimpic sailing gradually more different from sailing in general. If the policy is not changed, olimpic sailing will be so distant from normal sailing that its format, scoring, classes and even its existence will make no difference for the rest of the sport.
