Boats operating between sunset and sunrise ( hours vary by state),
or in conditions of reduced visibility, must use navigation lights.
Nighttime operation, especially during bad weather and fog, can be
dangerous. All Rules of the Road apply at night, but it is best to slow
down and stay clear of all boats regardless of who has the right-of-way.
To see more easily at night, avoid bright lights when possible. Also,
it is helpful to have a passenger keep watch for other boats, water
hazards and navigational aids.
To determine the size, speed and direction of other vessels at night,
you should use the running lights. A green light indicates starboard
side, and a red light indicates port side. Generally, if you see a green
light, you have the right-of-way. If you see a red light, give way to
the other vessel.
