Like we all said, sort of. :-) But, thanks for the technical clarification.

I did NOT say that. Look again, Joe. I said one sailboat was
catching up to the other. Since everybody seems clueless, I'll
give the answer. It's a crossing situation. Subtract the angles.
It has to be within a 22 and 1/2 degree angle of the centerline
to be overtaking. 208-180 = 28 degrees. Not overtaking.
Pay attention, Joe.

In a crossing situation the sailboat to windward must avoid the
other sailboat since they're both on the starboard tack.

This is FUN!

Cheers,

Sorry, Ellen, you have that wrong. Its 22.5 degrees behind the beam, not
a difference in course. If the two boats have those headings it could be
either overtaking or converging, which would make it crossing. However,
since you stated "catching up" its hard to make this into something that
isn't overtaking.
