Nothing to add to this Thread but speaking of navigational lights, I had
had an interesting experience I'll share.
When I was a novice boater 30+ years ago, we were boating at night at the 'ocean', (Narraganzett R.I).,and is was pretty dark, clear but dark ! Moving along at a good clip about 20 mph, and I noticed two white lights on the horizon, in front of me about a 'football field' apart. That said, I started to drive 'between' the two white lights.
As I got about 200 ft near that center point, I noticed what I was actually looking at was 300' barge, that had white lights at each end, bow and stern, and I was driving right between them. HOLY SH*T that was a close call. I was able to change course in time, but really gave us a scare.
After we got back to the dock and I changed my shorts
I had learned a very valuable lesson at driving at night, always be aware of your surroundings 360 degrees, and what you can't see that may be out there especially on the water at night.
