That, IMO is rubbish. At night before AIS, you knew when you have crossed a ship's path as you see his navigation lights change colour. Now, the OP has AIS so he can see the state of play with ships.
AIS helps, but
a) not all boats have it (and some fishing boats seem to turn it off)
b) the presence of AIS doesn't negate the sensible advice in Seajet's post (in my opinion).
Nav lights are another matter. On all of my single handed trips in the last few years, I have encountered a vessel which was so brightly lit up that its nav lights couldn't be established. It's also hard to see nav lights in the fog (another of Seajet's observations!)
