Navigation Rules

Every Marine Law Enforcement Officer should have a copy of this book.

Navigation RulesThe Navigation Rules or Rules of the

Road exist to prevent collisions between vessels.

These rules apply to ALL vessels, and their operators. (Rule 2 a)

Navigation Rules

Due regard shall be had to all dangers of navigation and collision. (Rule 2 b)

Vessels may depart from these Rules if necessary to avoid immediate danger. (Rule 2 b)

Definitions

Vessel: Any craft used as a means of transportation on the water (Rule 3 a)

Underway: Not at anchor, made fast to the shore, or aground (Rule 3 h)

Definitions

Power-driven: Propelled by machine (Rule 3 b)

Sailing: Under sail power alone - no propelling machinery is being used (Rule 3 c)

Definitions:Vessel engaged in fishing: Use of nets,

trawls, or other apparatus which reduces maneuverability (Rule 3 d)

Vessel not under command: Exceptional circumstance makes unable to maneuver (Rule 3 f)

Vessel restricted in ability to maneuver: Nature of work limits maneuverability (Rule 3 g)

Definitions:

Inland Waters

(Rule 3 l, m, o)

Other Terms:

Give way: Avoid a collision Take early and substantial action to keep

well clear of the stand-on vessel. (Rule 16)

STOPSLOW

Other Terms:Stand on: Avoid a collision

1.MUST, at first, keep course and speed;2.MAY take avoiding action if the give-

way vessel’s action is at all deficient3.MUST take avoiding action if the give-

way vessel gets so close that it alone can not avoid a collision (Rule 17 a, b)

Rule 2: Rule of Responsibility Comply with the Rules at all times, as

Rule 5: Proper Lookout

Each vessel shall maintain a proper look-out by sight and hearing (Rule 5)

Use all available means to assess the risk of collision (Rule 5)

Rule 6 : Safe Speed

Every vessel shall at all times proceed at a speed so that it can take proper and effective action to avoid collision (Rule 6)

Be able to stop within a distance appropriate to the prevailing circumstances and conditions (Rule 6)

Visibility and traffic density; A vessel’s maneuverability;Presence of background lights;The state of the wind, sea and current;The vessel’s draft in relation to the

available depth of water. (Rule 6 a)

In determining a safe speed, vessel operators should consider:

Lights

Rule 20: Application of Lighting RulesLighting rules apply:

from sunset to sunrise

in restricted visibility (fog, rain, etc.)

all other times it is deemed necessary

(Rule 20 c)

Lighting Rules:No other lights shall be displayed except

lights that:

cannot be mistaken for required lights

do not obscure required lights

do not interfere with keeping a proper look-out (Rule 20 b)

Rule 21: Light Definitions

Sidelights - green to starboard and red to port, visible from dead ahead to 22.5° abaft the beamMay be one (combination) light on vessels less than 20 meters

(Rule 21 b)

Masthead light for power-driven vessels - 225° white light visible from dead ahead to 22.5° abaft the beam on both sides (Rule 21 a)

Stern light - 135° white light showing aft (filling the dark zone of the sidelights) (Rule 21 c)

All-round light - 360° light showing all around the horizon (Rule 21 e)

The Steering and Sailing Rules

Rule 7 : Risk of CollisionEvery vessel shall use all appropriate

means to determine if risk of collision exists. If there is any doubt, such risk shall be deemed to exist. (Rule 7 a)

Proper use shall be made of radar equipment, if fitted and operational. (Rule 7 b)

Rule 7: Risk of Collision Risk of collision exists if the compass

bearing of an approaching vessel does not appreciably change. (Rule 7 d i)

Rule 8: Action To Avoid a CollisionAny action taken to avoid collision shall be:

Positive,Made in ample time,With due regard to good seamanship.

(Rule 8 a)

Alteration of course or speed must be large enough to be obvious to another vessel (Rule 8 b)

Action taken shall result in passing at a safe distance. (Rule 8 d)

Rule 8: Action to Avoid Collision

Effectiveness of the action shall be carefully checked until both vessels are clear. (Rule 8 d)

If necessary to avoid collision or allow more time to assess the situation, a vessel must slow down or stop. (Rule 8 e)

Rule 9: Narrow Channels

Vessels shall keep as close as possible to the right side of the channel. (Rule 9 a i)

Avoid anchoring in the channel. (Rule 9 g)

Narrow Channels Steering Rules for Great Lakes & Western Rivers A power-driven vessel going downstream

has the “right-of-way” over a vessel going upstream and must propose the manner and place of passage using appropriate signals. The other vessel must stop and hold its position as necessary to permit safe passing. (Rule 9 a ii)

Rule 9: Narrow ChannelsVessels less than 20 meters, sailing

vessels, and all vessels crossing a channel must stay clear of vessels confined to the channel. (Rules 9 b and d)

Vessels engaged in fishing must not interfere with any other vessel using the channel. (Rule 9 c)

Rule 13: Overtaking Any vessel overtaking any other is

When a vessel is in doubt as to whether it is overtaking, it shall assume that this is the case, and act accordingly. (Rule 13 c)

Rule 13: OvertakingTwo Short Blasts – “I intend to overtake you on my starboard side”

One Short Blast – “I intend to overtake you on my port side”

Whistle signals are found in Rule 34 c

If in agreement, the same signal shall be returned.

Rule 15: Crossing Situation When two power driven vessels are

This requirement does not apply to vessels under 12 metersThis requirement does not apply to vessels under 12 meters

Rule 35: Signals in Restricted Visibility A vessel at anchor shall:

ring a bell for 5 seconds at least every minute

may also sound 1 short, 1 prolonged and 1 short blasts ((Rule 35 f)35 f)
