Case 11:
In the photo below, W6 has just rounded the leeward mark and tacked to
starboard. W1191 is about to round the leeward mark. 1. Does being subject to rule 18 give W1191 any protection
from W6 here?
2. What limitations does rule 16 place on W6 here?
Answer:
1. No. Rule 18 only applies
between boats
that are "about to round or pass a mark ...", and here, only W1191 is
about to round or pass, so rule 18 cannot apply, and the situation
reverts to rule 10
(port/starboard).
2. W6 must not alter course in any way that will leave W1191
insufficient room to keep clear.
