The General Prudential Rule
The general prudential rule regarding right-of-way is that if
a collision appears unavoidable, neither boat has right-of-
way. As prescribed in the Rules of the Road, both boats
must act to avoid collision.
Night Running
Boats operating between sunset and sunrise (hours vary
by state), or in conditions of reduced visibility, must use
navigational lights.
Nighttime operation, especially during bad weather or 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 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 the starboard side, and a red light indicates the
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. See Figure 8-4.
