Question
Shortly before the start, B and Y, both on starboard, are approximately stationary near the starting line. A and X are approaching close hauled with A clear ahead of X when A is two lengths away from B’s transom. A then luffs slightly, causing X to luff and establish an overlap to windward of A. X has the opportunity to tack, but instead hails A for room to pass to leeward of B. A does not give X room, and there is contact between X’s bows and B’s transom. B protests. What should the call be?

Answer
When two boats are approaching an obstruction, even if that obstruction is a right-of-way boat, rule 18.2 determines an inside boat’s right to room. Because A is clear ahead of X when she reaches the two length zone of B, X is not entitled to room to pass between B and A. Rule 16.1 requires that A does not alter course if that prevents X from keeping clear. However, because X can tack at position 2, A fulfils her obligations under rule 16.1. X therefore breaks rule 12 when she makes contact with B. Penalize X.
