I am using the illustration below to call attention to one of this year's rule changes.

Consider first that what you see is a starting line with the Committee Boat at the port end. In both the old and new rules, the leeward boat had no right to hail for room to tack because the pertinent rule (19.1 old rules and 20.1 new rules) did/does not apply at a starting mark surrounded by navigable water or at its anchor line. See Rule 19.2 old rules, Preamble to Section C new rules.Fine for a start! Green can luff head to wind and hope for the best.
Now consider the illustration as depicting a finish line situation. Under the old rules 19.2 went on to say that 19.1 did not apply " at a mark that the hailed boat can fetch". Red is fetching so Green was in a tough spot. Green was not entitled to room to tack and her hail had no merit.
This (to my way of thinking) is how it should be! Red is in control and is just going to make it by the Committee Boat's anchor rode. Green should have gybed out while she had the chance.
Now along come the new rules and while they say Green should not hail in a situation like this, if she does hail, Red must be bound by the hail!
What's wrong with this you ask?
Well it suddenly shifts control of the situation to the boat that sailed into a "coffin corner" and shouldn't have been there in the first place. Second, although the rules are quite clear that Green broke rule 20.3, it places a burden on Red to have to file a protest to protect her finish position. Third, imagine a situation where two or three boats are stacked up to weather of Red and they are all fighting for the lead. Suddenly, they all have to tack because of Green's hail. Might some other protests arise?? Seems quite likely.
Will Green come up with a story to justify her hail? You bet!
This change was included in the new rules in the interest of safety but I'm not buying into it.
If you can't hail at a starting mark surrounded by navigable water, why can you hail at a finish mark surrounded by navigable water?
I think there are some good changes in the new rules but this wasn't one of them.
