Even on the most basic course I always teach them that one of the few lights that really matter are the two or three white lights of the tug. In general you know to avoid big boats but the tug is a special case because you can easily be deceived into trying to pass between the tug and the towed vessel because the latter looks to be miles astern when seen close by at night.

So yes - everyone should know the basic lights. If you dont, then dont go out at night.

Looks to me Tangomoon, as if you have a customer for your courses
