Rule 17.2 (On the Same Tack; Proper Course) has been deleted.

This means that a windward boat or a boat clear ahead no longer has a proper course limitation when sailing near other boats. She can sail below her proper course if she wishes, for instance to make it more difficult for a boat astern to pass or establish an inside overlap nearing a mark. Windward boats must still keep clear of leeward boats under rule 11 (On the Same Tack, Overlapped).
