This Week's Question

At an upwind finish, two close-hauled boats on opposite tacks (S and P) are converging at the left end mark of the finishing line. When about a length and a half from the mark, P completes a tack to leeward of S without fouling her. However, in order to pass the mark on the correct side, P luffs up to almost head to wind, thereby causing S to sail above close-hauled to avoid her. S protests P. You are on the protest committee; which boat should be penalized? (From Perry, Quiz 37)

Answer

Boat P is penalized for breaking rule 18.3, Tacking the Zone. As P and S are approaching the finishing mark on opposite tacks, rule 18, Mark Room, does not apply because the boats are on opposite tacks on a beat to windward. But once P tacks, the boats are no longer on opposite tacks and rule 18 begins to apply (see rule 18.1, When Rule 18 applies). When P and S are approaching a port-hand windward mark on the opposite tack and P then passes head to wind within the zone at the mark and is fetching the mark, rule 18.3 requires P to not cause S to sail above close-hauled to avoid contact. P causes S to sail above close-hauled to avoid contact; therefore, she breaks rule 18.3
