Here is a very interesting quote regarding Rule 18:
“Also with room at the mark – rule 18 – in the past there was one set of rules at the windward mark and a different set of rules at the leeward mark and we just eliminated that and it is the same at both. Right now the inside boat when they reach the zone, any outside boat owes them room. For example, if you are approaching a mark to round it to port, and you are on port tack, you have room at that mark. In the past you couldn’t come in on port tack at the weather mark, but under the new rules you can – you don’t have right of way over the starboard tacker, but the starboard tacker has to give you room to round the mark - which is the same situation as it’s been at the leeward mark for years. So we are just trying to make it symmetric up and down the course and trying to keep it simple.”Mike notes that he thinks -- or hopes -- that some of the AC RRS changes, such as the deletion of rules 13 and 17, will be incorporated into the ISAF RRS.
