Also I should mention, a boat coming fast from behind on Starboard at the gybe mark cannot call starboard on another boat that is on port and rounding the mark.
If the boat on starboard had the overlap in time then he could call for buoy room, but "starboard" is not relevant.
Does this also apply at a leeward Port rounding mark? You know the classic, spinnaker aproach on Starboard with a gybe drop.
