Errr! I'm afraid I have egg on my face. Your right. It IS an overtaking situation.
I was wrong. I got the 22 and 1/2 angle mixed up. I was thinking it was from the
center line at the back of the boat. Instead it's from the sideways line.
Overtaking is required to change course.

This would be the typical case but not necessarily.

If the boats were going at similar speeds, they could be converging
from a distance and seeing each other roughly on the beam. By
jiggling the speeds, you can find the point where one sees the other
at exactly 22.5 degrees abaft the beam. The question is, could this
be considered "catching up"?
