Rule 19.2(b), Room to Pass an Obstruction:
Giving Room at an Obstruction
Rule 19.2(c), Room to Pass an Obstruction: Giving
Room at an Obstruction
Rule 20.1(b), Room to Tack at an Obstruction: Hailing
and Responding
Rule 20.3, Room to Tack at an Obstruction: When
not to Hail
Definitions, Clear Astern and Clear Ahead;
Overlap
A boat that hails for room to tack before safety requires her to tack is entitled to receive room under rule 20.1(b), but by hailing at that time she breaks rule 20.3. An inside overlapped boat is entitled to room between the outside boat and an obstruction under rule 19.2(b) even though she has tacked into the inside overlapping position.

Additional Assumed Facts for Question 2
SL does not hail for room to tack. However, SW tacks between positions 2
and 3 at a point where, after she completes her tack, her close-hauled course
passes just to leeward of the end of the farther breakwater. Seeing SW tack,
SL immediately tacks as well.
Question 2
After position 2, is PL (formerly SW), required to give PW (formerly SL) room
between her and the breakwater?
Answer 2
Yes. When SW tacks, SL is able to tack without breaking a rule. When SW turns
past head to wind, the overlap between her and SL ceases to exist, because they
are then on opposite tacks and sailing at less than 90 degrees to the true wind
(see the definition Clear Astern and Clear Ahead; Overlap). A new overlap begins
when SL passes head to wind, at which time the boats are once again on the same
tack. After the new overlap begins PL, by bearing off, can easily give PW room
between her and the breakwater. Therefore, rule 19.2(b) applies and requires
PL to give PW that room.
Although the breakwater is a continuous structure from the shore to its outer
end, it does not qualify as a continuing obstruction because the boats pass
close to it only briefly, near its outer end. Therefore, rule 19.2(c) does not
apply.
