PART 2


Which Tack?


Which tack is Yellow on?


Note that it is not possible to decide the tack of a boat that is head to wind when first encountered. It depends how she became head to wind, as she is on the same tack as she was before she became head to wind.


She is on the same tack as before she was head to wind.

Definition 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.


Yellow and Red are overlapped Red and Blue are overlapped Yellow and Blue are overlapped.


They are still not overlapped - Blue's spinnaker is not in normal position.


If boats are on the same tack, they are either overlapped, or one is clear astern of the other, making the other clear ahead.


Yellow and Red are overlapped Red and Blue are overlapped


Yellow and Blue are NOT overlapped.


They are now overlapped, with reference to Blue’s bow.


If boats are on opposite tacks, they may also be overlapped before or at marks and down- wind obstructions. That does not change the applicable right-of-way rule, but permits the separate requirements for overlaps in rules 18 and 19 to apply to them.
