WF2-17
ON THE SAME TACK BEFORE A REACHING START
Rule 17 is changed to:
When, at the warning signal, the course to the first mark is approximately ninety degrees from the true wind, during the last 30 seconds before her starting signal a wingfoil overlapped to leeward of another wingfoil on the same tack shall not sail above her shortest course through the starting line to the first mark while they remain overlapped if as a result the other wingfoil would need to take action to avoid contact, unless in doing so she promptly sails astern of the other wingfoil.
