The keeper of the rules, World Sailing, has recognized that "high speed sailing" might need some modifications to the RRS.

I'm not sure how many true rules experts we have here, but I know that these new rules or modifications to the rules are mainly for catamarans racing a course.

They aren't easy to find, so I've posted them for your comments.

First a link to the official RRS as they stand.

This is a document titled
High Speed Test Rules
That lists the proposed new rules and how they might be used by a class or event.

Some of these rules you may have heard mentioned during the AC coverage and they have already been used in the Ultimate Sailing events and the GC32 series.

A lot of these rules could simply be "sport catamaran rules", more room at marks etc. These are up for adoption by the Nacra 17 (Olympic) class with the new foiling MKII version.

What do you think?
