Two boats converging on opposite tacks — which one gives way?
The port-tack boat, every time. Under Rule 10 a boat on port tack must keep clear of a boat on starboard tack. The starboard boat holds her course; the port boat ducks to leeward or tacks away early. Who is ahead, who is faster, and how big the gap looks are all irrelevant — the tack decides it.
