Motor (including motor sailing) Tugs are treated as motor vessels, unless they are also RAM or CBD Exceptions to General Rules: Narrow channels Traffic Separation Schemes.  Overtaking boats keep clear - sail and power.  Sailing Rules 1. Starboard tack boat 2. Port tack boat Sailing boats on the same tack: Windward boat keeps clear.  Motoring Rules Boats meeting head on - both turn to starboard. If two power vessels are crossing, the boat which has the other on her own starboard side shall keep out of the way.
