CHANGES TO THE DEFINITIONS
The definitions Mark-Room, and Tack, Starboard or Port are changed to:
Mark-Room Mark-Room for a board is room to sail her proper course to round or pass the mark.
Tack, Starboard or Port A board is on the tack, starboard or port, corresponding to the competitor’s hand that would be nearer the mast if the competitor were in normal sailing position with both hands on the wishbone and arms not crossed. A board is on starboard tack when the competitor’s right hand would be nearer the mast and is on port tack when the competitor’s left hand would be nearer the mast.
