I agree with all of your points, Eric. But who suggested changing RRS 42 in SIs?

There are plenty of class rules which change RRS 42. Many dinghy classes and board classes, including Olympic classes do this. Collegiate procedural rules (treated like class rules, which is an interesting work-around) also change RRS 42.

Having said that, I also never said that this should be taken lightly. Careful consideration needs to be made to avoid unintended consequences. There is usually a trial period before committing to an actual change.

The only reason that I brought this up is to make people aware that the rules do allow (limited) flexibility in this regard.
