Aids To Navigation - MARKER ONE m25, m27 Owner's Manual

Overtaking
The boat that is overtaking one ahead of it is the
burdened boat and must make any adjustments
necessary to keep out of the way of the privileged
boat. The privileged boat should hold its course
and speed.
Special Situations
Boats operating between sunset and sunrise
(hours vary by state) must use navigational lights,
nighttime operation, especially during bad weather
or fog can be dangerous. All "Rules of the Road"
apply at night; it is best to slow down and stay clear
of all boats, regardless of who has right-of-way.
Protect your night vision by avoiding bright lights
and have a passenger, if possible, help keep watch
for other boats, water hazards and aids to
navigation.

The size, speed and direction of the other vessels
are determined at night from their running lights. A
green light indicates the starboard side of the boat,
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 that vessel.

Aids to Navigation

Learn to recognize the different buoys and day
markers; they are the signposts of the waterways.
The United States Aids to Navigation System
(USATONS) is the primary marking system used on
inland water, coastal waters and rivers. This system
is maintained by the U.S. Coast Guard (USCG).
Types of Buoys
There are several types and shapes of buoys.
Buoys may be unlighted, lighted, with sound or may
have both an audible and a visual signal. Lights,
bells and horns are used on buoys for night or poor
visibility conditions. Different shapes of buoys are
shown below.
