Question
Blue and Yellow are sailing downwind on port tack. Blue has an outstanding penalty. She luffs, passes head to wind, and bears away to a close-hauled course on starboard tack. Yellow changes course to avoid a collision before Blue achieves a downwind course. Blue continues to bear away and achieves a downwind course. Both boats Y-flag. What should the call be?

Answer
Signal that Blue has completed a penalty and then penalize Blue again. Blue did comply with rule C7.2(a)(2) and so completed a penalty. However, before returning to a downwind course she broke rule C2.8.
