Situation (not subject to a hearing or proceeding)
A windward - leeward course with a leeward gate in light variable winds. Due to a strong current, one of the gate marks had drifted to leeward on the same bearing from the windward mark.
The mark-drift was noticed by the race officer as the fleet rounded the windward mark. A mark-boat was deployed to reset the mark in its original position which was completed when the fleet was half way down the leeward leg.
After racing, a competitor suggested that the proper process for moving a mark (sound warnings from a boat at the previous mark with a board showing the new bearing and/or distance) was not followed.
Should the race officer have warned of a course change when resetting the mark to its original position?
