Mark Room when Boats are in different classes and on different Legs of the Course
In 4-5 knots of wind with no current and flat seas, 2 boats from different classes (Laser 28 and CC 29) were on port jibe going downwind on a LA2 course (per Appendix S , modified so that the finish was to the right of the committee boat) Boat A was sailing to the finish, while Boat B was sailing to the starboard Gate Mark. Boat A established an overlap from behind (17 overlap) about 8 boatlengths from the Zone of the Gate mark sailing a slightly higher course than Boat B. When entering the Zone of the Gate Mark Boat B (the inside overlapped windward boat) asked for Mark Room to which they felt they were entitled to. Boat A elected to come up hard and attempt to pass Behing Boat B and struck then in the Starboard Quarter just forward of the stern pulpit causing no damage or injury and carried Boat A past the mark. When Boat B attempred to go back and reround the mark she was unable to do so as Boat A was doing penalty turns. Eventually she was able to reround the mark and finish her race as was Boat A who sailed to the finish. Prior to entering the zone the 2 boats had a discussion and Boat A was aware thet Boat B was headed to the Gate Mark.
Boat A was in a different class on a different leg of the course and was saioing her proper course when she interfered with Boat B.
Q1. Was Boat B entitled to Mark Room even though the boat to give Mark Room was in a different class and on a different leg of the course?
Q2 Aside from breaking Rules 14,16.1,44.2, and 18.2.a
