Overtaking a Boat To Starboard or Port Side
The stand-on boat (the boat being overtaken) must maintain its course
and speed.
If the give-way boat wishes to overtake and pass on your port side, it must
signal with two short (1 second) blasts.
If the give-way boat wishes to overtake and pass on your starboard side, it
must signal with one short (1 second) blast.
To signal that the course ahead is not safe for passing, the stand-on vessel
must signal for danger by sounding five or more short, rapid blasts.
If you have doubts or there is danger of collision, give five or more short
and rapid blasts to signal danger.
Approaching Other Boats
Normally, motorboats should keep clear of sailboats.
Motorboats and sailboats must stay out of the way of vessels not under
command and vessels engaged in fishing.
Sailboats using auxiliary (backup) engines operate under the same rules
as motorboats.
Sailboats should keep out of the way of other sailboats to prevent the risk
of collision.
Sailboats and boats propelled by oars and paddles usually have the right-of-
way over motorboats, because they are harder to maneuver.
Sailboats and paddle craft should not interfere with large vessels, other
power boats or “working” boats such as fishing vessels and dredges.
Large, deep-draft vessels in narrow channels have the right-of-way because
they cannot maneuver easily and may have limited visibility. Avoid large
ships by staying out of the way, remaining visible, maintaining a lookout,
knowing the signals, anchoring in safe places and using the radio.
Be especially alert if you are sailing in a deep-water channel or port,
because a large ship can “steal your wind.”
Pulling a water skier in a heavy-use area means you need to be extra
cautious.
Approaching a Blind Bend
When your boat is approaching a blind bend, you should signal with one
prolonged (4 to 6 seconds) blast.
An oncoming boat should return the signal.
Motorboats shall keep to the starboard (right) side of the bend or channel
whenever it’s safe or practical.

KNOW AND REMEMBER
On the road, drivers use lane lines
and stoplights to stay safe. But
boaters don’t have lines or stop
lights on the water, so they must be
extra cautious. And, unlike motor
vehicles on the road, boats don’t
have brakes. On the waterways, it’s
very important
to follow the “rules
of the road.”
