This evening we were sitting on the breakwater dock at Rosario (Orcas Island, WA). When a huge bright lite appeared coming around the point about 3 miles away. By the time it got to us it was blinding. Some dufus in a sport fishing boat had a light bar across the top of his pilot house. It would destroy anyone's night vision within a mile. Seems to me this may not be legal. I found some non-official references that say the only lights that should be visible to other boats are the red, green and white running lights.
