on another note...  I was chastised by the Coasties for shining my spot at their boat...  They told me it was illegal...  They were floating in a direct path from Chicago to the Cal Sag channel (looking for drunks I bet.)  But they were spinning around and around...  I could not get a good fix on their nav. lights, so I hit them with a spot..  Man were they pissed...  I have STILL never figured out if I did anything wrong.
If another vessel is maneuvering erratically, after dark, then there really isn't much other than the spot to help make a safe call on what the heck is happening.  I had to do something similar when a small whaler was weaving about in a channel ahead of me.  It was a boatload of kids, the spot snapped them right to attention and got them to quit the shenanigans (at least until I passed by).
