Case 10:
In the photo below, 1. does rule 12 (overtaking boat) apply? Why (not)?
2. Which rule definitely applies here?
Answer:
1. No. The name of rule 12
says it all: ON THE SAME TACK, NOT OVERLAPPED.
These
boats are not overlapped but are also not on the same tack.
Therefore, ...
2. rule 10 (port/starboard)
applies.
