Section G – The Run
TR CALL G6
Rule 11, On the Same Tack, Overlapped
Rule 17, On the Same Tack; Proper Course
Rule 19, Room to Pass an Obstruction
Question 1
B and X are overlapped on port tack on a downwind leg. B is subject to rule 17. Both
boats are on collision course with Y on starboard tack. X hails for room to gybe but B
luffs to pass astern of Y, which is a proper course for B. X keeps clear and protests.
What should the call be?
Answer 1
No penalty.
Rule 19 applies between boats at an obstruction. The right-of-way boat may choose to
pass an obstruction on either side. X must keep clear of B, and B must not sail above
her proper course. X keeps clear of B and gives her room while she does so.
Question 2
How close to the obstruction can B be before she makes her choice?
Answer 2
If B chooses to luff, she must be far enough from Y to keep clear of Y and enable X to
keep clear of both B and Y. See also call L10.
If B chooses to gybe, she must be far enough from Y to give X room under rule 19.2(b)
to pass on the same side of Y.
