One suggestion: Ships/boats, engaged in different forms of work, such as
survey, fishing, offshore supply, tend to be of a type/shape and size,
coupled
with running at slower speeds (in some cases) when working.

Here is a picture of the boat in question

It looked like a coastal freighter from our boat. It was doing about 12-15
kts (guess). There was nothing unusual about its speed.



With this in mind, don't just look for lights and shapes. Mentsally
picture
what you are looking at, and try to categorize, while thinking of the
possible
maneuvers, etc. it could be doing, if it falls into one of your categories
.....
it may give you something to start working on for possble actions he will
take
as well as what you can do.

I realize the above is kinda vague, but I always try to figure out type,
size,
nationality, where from and to, and what it may be doing out of the
ordinary,
so I can start developing plan A,B,C, ......

Likewise!
