If a boat breaks rule 30.2 or rule 30.4 during a starting sequence that results in a general recall, the race committee is required to penalize her even if the race had been postponed before that starting sequence or if, during a later starting sequence, a postponement was signaled before the starting signal.

A boat that makes, and does not correct, an error in sailing the course does not break rule 28.1 until she finishes. If a boat makes such an error, a second boat may notify the first that she intends to protest before the first boat finishes, or at the first reasonable opportunity after the first boat finishes.

An explanation of the application of rule 20 when three boats sailing close-hauled on the same tack are approaching an obstruction and the leeward-most boat hails for room to tack, but cannot tack unless both boats to windward of her tack.

When a boat is entitled to room, the space she is entitled to includes space for her to comply with her obligations under the rules of Part 2 and rule 31.

Interpretation of the word “new” as used in rule 66.

A discussion of redress in a situation in which a boat is damaged early in a series, is entitled to redress under rule 62.1(b), and is prevented by the damage from sailing the remaining races. In such a situation, to be fair to the other boats in the series, the protest committee should ensure that fewer than half of the race scores included in her series score are based on average points.

When three boats are on the same tack and two of them are overlapped and overtaking the third from clear astern, if the leeward boat astern becomes overlapped with the boat ahead, the boat ahead is no longer an obstruction, and rule 19.2(b) does not apply. There are no situations in which a row of boats sailing close to one another is a continuing obstruction.

In the definition Mark-Room, the phrase “room to sail to the mark” means space to sail promptly in a seamanlike way to a position close to, and on the required side of, the mark.

When a race is conducted for boats racing under a rating system, the rating that should be used to calculate a boat's corrected time is her rating at the time the race is sailed. Her score should not be changed if later the rating authority, acting on its own volition, changes her rating.

“Information freely available” in rule 41(c) is information that is available without monetary cost and that may be easily obtained by all boats in a race. Rule 41(c) is a rule that may be changed for an event provided that the procedure established in the rules is followed.
