Overlap Meaning in Sailing

Overlap occurs when the front of one boat is further forward than the back of another. This horizontal relationship is critical for determining right-of-way during a race or near a mark. An official determines an overlap exists by looking at a line drawn from the rear of the boat. A trailing boat establishes an overlap by steering its bow past the stern of the leader. This position often gives the inside boat the legal right to space at the next turn. The crew must shout to the other boat to acknowledge that an overlap has been made. Understanding this concept prevents collisions when many boats try to turn around a single buoy. Breaking an overlap requires the trailing boat to fall back completely behind the lead vessel.
