      • Applies exclusively to US inland waters

  • NOTE: Navigation Rules have the force of law.


Rule 1 a applicability l.jpg

Rule 1(a): Applicability

  • Nav Rules apply based upon a vessel’s location.

    • COLREGS Line of Demarcation

  • “These rules shall apply to all vessels upon the high seas and in all waters connected therewith navigable by seagoing vessels.”


Rule 2 responsibility l.jpg

Rule 2: Responsibility

  • “Nothing in these Rules shall exonerate any vessel, or the owner, master or crew thereof, from the consequences of any neglect to comply with these Rules or of the neglect of any precaution which may be required by the ordinary practice of seaman.”

  • General Prudential Rule: the mariner is responsible not only for complying with the Rules but also for avoiding a collision.

    • Special Situations

    • In extremis situations


Slide8 l.jpg

Special Situations(not covered by the Rules)

  • Examples:

    • Laying navaids

    • Dredging/Surveying

    • UNREP

    • Flight Ops

    • Mineclearance Ops


Rule 3 definitions vessel constrained by draft l.jpg

Rule 3: DefinitionsVessel constrained by draft

  • Vessel constrained by draft means a power driven vessel which, because of her draft in relation to the available depth is severely restricted in her ability to deviate from her present course.


Rule 3 definitions underway not underway l.jpg

Rule 3: DefinitionsUnderway, Not-underway


Rule 3 definitions restricted visibility l.jpg

Rule 3: DefinitionsRestricted Visibility


Rule 3 definitions restricted visibility18 l.jpg

Rule 3: DefinitionsRestricted Visibility

  • Fog

  • Falling snow

  • Heavy Rainstorms

  • Sand storms

  • Similar circumstances


Slide19 l.jpg

Rule 3: DefinitionsWIG

Wing-in-ground (WIG) craft: a vessel capable of operating completely above the surface of the water on a dynamic air cushion created by aerodynamic lift due to the ground effect between the vessel and the water’s surface. WIG craft are capable of operating at speeds in excess of 100 knots.


Slide20 l.jpg

Rule 4: Application

Defines the application of rules 5-10

These rules apply in ANY visibility


Rule 5 look out l.jpg

Rule 5: Look-out

  • Application (Rule 4) - Any condition of visibility

  • Look-out (Rule 5)

    • Maintain Proper Lookout

    • Use all available means

      • Binoculars/Radar

      • Bearing circle/Alidade

      • Must use sight and hearing

      • Night vision devices

    • Also required at anchor


Rule 6 safe speed l.jpg

Rule 6: Safe Speed

  • Determinants of Safe Speed

    • State of visibility

    • Traffic density

    • Stopping distance and turning ability

    • Presence of background lighting

    • State of winds, sea, and current

    • Draft of vessel in relation to charted depth

    • Effectiveness of Radar


Rule 7 risk of collision l.jpg

Rule 7: Risk of Collision

  • Risk of Collision (Rule 7)

    • Use all available means to determine

    • Early use of RADAR

    • Don’t make assumptions

  • Risk of collision exists when vessels have:

    • CBDR: Constant Bearing, Decreasing Range

    • Very High Bearing Drift

    • Bearing drift is the most important determinant of risk of collision


Rule 8 action to avoid collision l.jpg

Rule 8: Action to Avoid Collision

  • Obedience must be timely and substantial.

  • Two variables can be altered to avoid collision: course and speed.

    • Change course to avoid “close-quarters” situations

    • Slacken speed or take all way off to avoid collision

  • Escape Clause:“if the circumstances of the case admit”

    • You are not required to put yourself in a worse condition to avoid collision (e.g.. run aground)


Rule 9 narrow channels l.jpg

Rule 9: Narrow Channels

  • Narrow Channels (Rule 9)

    • Stay on the “right” side of the channel

    • Sailing vessels and vessels < 20 meters shall not impede vessels restricted to the channel.

    • Fishing vessels shall not impede

    • Crossing vessels shall not impede


Rule 10 traffic separation schemes l.jpg

Rule 10: Traffic Separation Schemes

  • Traffic Separation Schemes (Rule 10)

    • Use small angle of approach to enter/depart

    • Cross the scheme at right angles

    • You can fish in the lanes as long as you do not impede passage of the other vessels


Rule 10 traffic separation schemes27 l.jpg

Rule 10: Traffic Separation Schemes

2. CROSS AT RIGHT ANGLES

3. ENTER @ SMALL ANGLE

1. PROCEED IN APPROPRIATE LANE

4. AVOID ANCHORING


Slide28 l.jpg

Rule 11:Conduct of Vessels in Sight of One Another

  • Application rule Rules 12-18

  • Applies to all vessels in sight of one another


Vessels in sight of one another rule 12 sailing vessels l.jpg

Vessels in Sight of One AnotherRule 12: Sailing Vessels


Vessels in sight of one another rule 13 overtaking l.jpg

Vessels in Sight of One AnotherRule 13: Overtaking

  • Rule 13 requires the overtaking vessel to keep out of the way of the vessel being passed.

    *a vessel 22.5 abaft the beam is overtaking – all others are crossing situations An overtaking situation exists when a vessel approaches

  • An overtaking situation exists when a vessel approaches another vessel more than 22.5deg abaft the beam.


Vessels in sight of one another rule 14 meeting head on situation l.jpg

Vessels in Sight of One AnotherRule 14: Meeting (Head-on) Situation

  • Two vessels who are on reciprocal (or near reciprocal) courses and are at risk of collision

  • Rule 14 requires both power vessels to maneuver to starboard.

    An overtaking situation exists when a vessel approaches

  • A meeting situation exists if two power vessels approach on reciprocal or near reciprocal courses.

  • Because of the nature of the situation, there is no giveway vessel. Both are responsible to maneuver


Vessels in sight of one another rule 15 crossing situation l.jpg

Vessels in Sight of One AnotherRule 15: Crossing Situation

  • Rule 15 requires the vessel that has the other on its starboard side to keep clear.

    An overtaking situation exists when a vessel approaches

  • At night the stand-on vessel sees the green sidelight of the give-way vessel, and the give-way vessel sees the red sidelight of the stand-on vessel.


Rule 15 cont l.jpg

Give-way

Rule 15 (cont)

Crossing Situation


Rule 16 give way vessel l.jpg

Rule 16: Give-way Vessel

  • Take early and substantial action to stay out of the way of the stand-on vessel


Rule 17 stand on vessel l.jpg

Rule 17: Stand-on Vessel

  • Maintain course and speed

  • Take action if the give-way is not taking substantial action to avoid collision

  • If risk of collision exists and if circumstance admit it, avoid altering course to port.


Rule 18 responsibilities between vessels l.jpg

Rule 18: ResponsibilitiesBetween Vessels

  • Vessel being Overtaken

  • Vessel Not under command

  • Restricted in ability to maneuver

  • Vessel Constrained by draft

Rule 19 conduct of vessels in restricted visibility l.jpg

Rule 19: Conduct of Vessels in Restricted Visibility

  • For vessels not in sight of one another

  • Observe a safe speed and have engines ready for immediate maneuvering.

  • Avoid altering course to port when another may exist forward of beam (except in overtaking situation)

  • Avoid altering course towards a vessel abeam or abaft the beam.

  • For fog signals heard forward of the beam=> reduce speed to minimum steerageway and navigate cautiously.

  • Where it’s impracticable for a seaplane to exhibit lights and shapes of the rules of the road, they shall exhibit lights and shapes as closely similar in characteristics and position as possible


Rule 32 sound and light signals international vs inland l.jpg

Rule 32: Sound and Light SignalsInternational vs. Inland

INTERNATIONAL RULES:

  • Sound signals for International Rules are signals of action

  • Signals are sounded upon rudder order

  • Exchanged by a power-driven vessel and another vessel

  • Exchanged if vessels are “in sight” and maneuvering is req’d

    INLAND RULES:

  • Sound signals for Inland Rules are signals of intent

  • Vessels do not maneuver until signals are agreed upon

  • Exchanged between power-driven vessels only

  • Exchanged if vessels are “in sight” and < ½ nm CPA


Rule 32 sound and light signals l.jpg

Rule 32: Sound and Light Signals

  • Short Blast- about one second duration

  • Long Blast - 4-6 second duration

  • Vessels < 100m in length: whistle and bell
