Section D - The Leg of the Course to a Windward Mark

MR CALL D2

Rule 10, On Opposite Tacks
Rule 16.1, Changing Course

Question

Blue and Yellow approach one another on a leg of the course to a windward mark. As Yellow bears away to pass Blue's stern, Blue luffs. Yellow attempts to bear away more but there is contact between the port quarter of Blue and the bow of Yellow. Flag Y is displayed. What should the call be?

Answer

Provided the umpires are satisfied that Yellow was keeping clear before Blue luffed, Blue broke rule 16.1 by changing course without giving Yellow room. Penalize Blue.
