A term used as stated below is shown in italic type or, in preambles, in bold italic type. The meaning of several other terms is given in Terminology in the Introduction.

A race that a race committee or protest committee abandons is void but may be resailed.

Clear Astern and Clear Ahead; Overlap
One boat is clear astern of another when her hull and equipment in normal position are behind a line abeam from the aftermost point of the other boat's hull and equipment in normal position. The other boat is clear ahead. They overlap when neither is clear astern. However, they also overlap when a boat between them overlaps both. These terms always apply to boats on the same tack. They apply to boats on opposite tacks only when rule 18 applies between them or when both boats are sailing more than ninety degrees from the true wind. 


Conflict of Interest
A person has a conflict of interest if he
(a) may gain or lose as a result of a decision to which he contributes,
(b) may reasonably appear to have a personal or financial interest which could affect his ability to be impartial, or
(c) has a close personal interest in a decision.

A boat is fetching a mark when she is in a position to pass to windward of it and leave it on the required side without changing tack.

Used in Rules: Mark-Room, 18.3, 20.1

A boat finishes when, after starting, any part of her hull crosses the finishing line from the course side. However, she has not finished if after crossing the finishing line she
(a) takes a penalty under rule 44.2,
(b) corrects an error in sailing the course made at the line, or;
(c) continues to sail the course.

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.


Leeward and Windward
A boat's leeward side is the side that is or, when she is head to wind, was away from the wind.  However, when sailing by the lee or directly downwind, her leeward side is the side on which her mainsail lies.  The other side is her windward side.  When two boats on the same tack overlap, the one on the leeward side of the other is the leeward boat.  The other is the windward boat.

 An object the sailing instructions require a boat to leave on a specified side, a race committee boat surrounded by navigable water from which the starting or finishing line extends, and an object intentionally attached to the object or vessel.  However, an anchor line is not part of the mark.
