Rules authority Dave Perry helps explain some of the significant changes to The Racing Rules of Sailing for 2013-2016. Perry is chairman of the US Sailing Appeals Committee, and has served as Rules Advisor to the US Olympic Sailing Team.
Definition of 'Keep Clear' Expanded...
The second part of the definition 'Keep Clear' has been expanded to apply to port and starboard tack boats as well as windward and leeward boats. If a port-tack boat allows herself to get so close to a starboard-tack boat that the starboard-tack boat cannot change course in both directions without making immediate contact with the port-tack boat, the port-tack boat has failed to keep clear. This commonly occurs when the boats are sailing dead downwind.
Keep Clear - A boat keeps clear of a right-of-way boat
(a) if the right-of-way boat can sail her course with no need to take avoiding action and,
(b) when the boats are overlapped, if the right-of-way boat can also change course in both directions without immediately making contact.
