From the Racing Rules of Sailing 2005 - 2008:

RIGHT OF WAY
A boat has right of way when another boat is required to keep clear of her.
However, some rules in Sections B, C and D limit the actions of a right of way
boat.

• Rule 10, ON OPPOSITE TACKS
  When boats are on opposite tacks, a port-tack boat shall keep clear of a
  starboard-tack boat.


• Rule 11, ON THE SAME TACK, OVERLAPPED
  When boats are on the same tack and overlapped, a windward boat shall
  keep clear of a leeward boat.


• Rule 12, ON THE SAME TACK, NOT OVERLAPPED
  When boats are on the same tack and not overlapped, a boat clear astern
  shall keep clear of a boat clear ahead.


• Rule 13, WHILE TACKING
  After a boat passes head to wind, she shall keep clear of other boats
  until she is on a close-hauled course. During that time rules 10, 11
  and 12 do not apply. If two boats are subject to this rule at the same
  time, the one on the other’s port side or the one astern shall keep clear
