Rule 13 While Tacking
Rule 18.2(a) Rounding and Passing Marks and Obstructions: Giving Room; Keeping Clear. Overlapped – Basic Rule
Rule 18.2(b) Rounding and Passing Marks and Obstructions: Giving Room; Keeping Clear. Overlapped at the Zone

Question 1
Approaching a starboard-hand windward mark on starboard tack, A and X are overlapped and level at the two-length zone. A gives X sufficient room to luff to head to wind, but when X begins to tack, her stern swings and hits A. A protests. What should the call be?

Answer 1
A is right-of-way outside boat when X reaches the two-length zone, and must give X room to round the mark. Tacking is a normal part of rounding this mark. A fails to give X room to tack round the mark. Penalize A, and exonerate X for breaking rule 13 under rule 64.1(b).

Question 2
At the same mark A and X are just overlapped on starboard tack at the twolength zone with A behind. A quickly becomes clear astern, but then changes course to be directly behind X. As X’s stern draws level with the mark, A hails 'Don’t tack in my water' and prevents X from tacking round the mark. X protests. What should the call be?

Answer 2
A is right-of-way outside boat when X reaches the two-length zone, and must give X room to round the mark. This obligation does not cease when A becomes clear astern. A fails to give X room to tack round the mark. Penalize A.

Room to round or pass includes room to tack when this is a normal part of the manoeuvre.
