Case 43:
In
the photo below, Rebel 4164 tacks to starboard right at the windward
mark and just in front of the Rebel already laying the mark on
starboard. In addition to the obvious risk of infringing rule 13
(tacking too close), in what other way does 4164 foul the other boat
here?
Answer:
1. 4164 is breaking rule 18.3(a)
by forcing
"the other boat to sail above close-hauled to avoid her".
