Default My seamanship question #1

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,
Ellen



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.
