Team Race - CALL E 13      

Rule 10 On Opposite Tacks
Rule 11 On the Same Tack, Overlapped
Rule 13 While Tacking
Rule 23.2 Interfering with Another Boat

Question 1
X and A are approaching a windward mark to be left to starboard. A is clear ahead when she enters the zone. X leaves the mark to port. A passes head to wind, but cannot bear away to a close-hauled course because of the presence of X. A protests.
What should the call be?

Answer 1
Penalize both, X for breaking rule 23.2 and A for breaking rule 13. When rule 23 applies, the rules of Section A continue to apply.
A has already sailed to the mark and must now sail to the next mark to continue sailing the course. X still needs to sail to the required side of this mark, to continue to
sail the course. Therefore, they are on different legs of the course.

Question 2
A has rounded the mark and is on the next leg. X is rounding the mark. Rule 17 does not apply to A. A luffs above her proper course to slow X. X protests. What should the call be?

Answer 2
No penalty.
As both boats are sailing toward the next mark, they are on the same leg. Therefore, A does not break rule 23.2.

When boats are rounding a mark on the same required side, even when one or both of them may be making a very wide rounding, they are sailing on the same leg. After the starting signal, a boat that passes the wrong side of a mark is not on the same leg of the course as a boat that is passing the mark on the required side.
