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.

The only thing that makes it overtaking is the situation on the water. The
terminology used to pose the question doesn't make it so. The original
question, as posed, didn't have enough information to determine whether the
situation was an overtaking one.
