Definitions, Obstruction
Question 1
B and Y are overlapped on port tack approaching X on starboard tack. Y sails to pass
astern of X; B attempts to sail between X and Y but there is insufficient space and she
makes contact with Y. Y protests. What should the call be?
Answer 1
Because both B and Y must keep clear of X, X is an obstruction and rule 19 applies.
Rule 19.2(b) requires that the outside boat give the inside boat room between her and
the obstruction. Penalize Y as she fails to give room.
Rules 10 and 11 also apply and require B to keep clear of X and Y. However, B is
exonerated under rule 43.1(b) for breaking either rule because she is sailing within the
room to which she is entitled from Y, and her breach is a consequence of Y's failure to
give her that room.
Question 2
The situation is the same, except that at position 1 Y hails ‘No room’. B tacks and
protests. What should the call be?
Answer 2
In this case, it is clear to B that Y will not give room. B complies with rules 11 and 14
by tacking.
Y and B are overlapped when they are at the obstruction and rule 19.2(b) requires Y to
give B room between her and the obstruction. Penalize Y as she fails to give room.
