Purpose of Scope of the Rules of the RoadSources:– 1972 COLREGS (International Rules) Regulations for the Prevention of Collisions at Sea Amended in 1983, 1989, 1991 by the IMO– 1980 Navigation Rules Act (Inland Rules) Applies exclusively to US inland watersNOTE: Navigation Rules have the force of law.
  4. 4. Rule 1(a): ApplicabilityNav Rules apply based upon a vessel’slocation. – 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.”
  5. 5. Rule 2: Responsibility“Nothing in these Rules shall exonerate any vessel, orthe owner, master or crew thereof, from theconsequences of any neglect to comply with these Rulesor of the neglect of any precaution which may berequired by the ordinary practice of seaman.”General Prudential Rule: the mariner is responsible notonly for complying with the Rules but also for avoiding acollision. Special Situations In extremis situations
  6. 6. Special Situations(not covered by the Rules)
  7. 7. Rule 3: General DefinitionsVessel Underway – Power driven vessel – Making way – Sailing vessel – Not making waySpecial Conditions Vessel engaged in fishing Not under command Restricted in ability to maneuver Constrained by draft (int’l rules only)
  8. 8. Rule 3: Definitions Vessel Vessel: includes every description of water craft used or capable of being used as a means on transportation on water.• Includes: – Power-driven vessels – Sailboats – Seaplanes – Non-displacement craft• “Power driven vessel”
  9. 9. Rule 3: Definitions Vessel engaged in fishing Vessel engaged in fishing means any vessel fishing with nets, lines, trawls or other fishing apparatus which restrict maneuverability.• Does NOT include: – Vessel engaged in trolling.
  10. 10. Rule 3: Definitions Vessel not under command Vessel not under command means a vessel which through some exceptional circumstances is unable to maneuver to comply with the Rules.• Examples: – Propulsion casualty – Steering casualty
  11. 11. Rule 3: Definitions Vessel restricted in ability to maneuver Vessel restricted in ability to maneuver means a vessel which from the nature of her work is unable to keep out of the way of another vessel.• Examples: – Laying navaids – Dredging/Surveying – UNREP – Flight Ops – Mineclearance Ops
  12. 12. Rule 3: Definitions Vessel constrained by draftVessel constrained by draft means a powerdriven vessel which, because of her draft inrelation to the available depth is severelyrestricted in her ability to deviate from herpresent course.

Rule 20: Application of Lights and DayshapesLights shall be displayed:– From sunset to sunrise– In conditions of restricted visibility– In all other circumstances when deemed appropriatePurpose of Lights and Dayshapes:– Helps determine stand on/give way status.– Indicates the occupation of certain vessels.– Aids in the determination of target angle and course.

  29. 29. Rule 4: Application Rule 5: Look-outApplication (Rule 4) - Rules in this section apply in Any condition of visibility.Look-out (Rule 5)– Maintain Proper Lookout– Use all available means Must use sight and hearing Binoculars/Radar Bearing circle/Alidade Night vision devices– Also required at anchor
  30. 30. Rule 6: Safe SpeedDeterminants of Safe Speed– Draft of vessel in relation to charted depth– Stopping distance and turning ability– Presence of background lighting– State of winds, sea, and current– State of visibility– Traffic density
  31. 31. Rule 7: Risk of CollisionRisk of Collision (Rule 7)– Every vessel shall use all available means to determine if risk of collision exists. Early use of RADAR Systematic observationSuch risk is deemed toexist if the compass bearing of an approaching vessel does not appreciably change.
  32. 32. Rule 8: Action to Avoid CollisionAny action taken to avoid collision shall … bepositive, made in ample time, and with dueregard to the observance of good seamanship. – Action taken must be positive and timely.Action taken to avoid collision with anothervessel shall result in passing at a safe distance.The effectiveness of the actionshall be carefully checked until thevessel is passed and clear.
  33. 33. Rule 8: Action to Avoid CollisionTwo variables can be altered to avoid collision:course and speed.– Change course to avoid “close-quarter situations”.– Slacken speed or take all way to allow more time to assess the situation.Escape clause: “if the circumstances of the case admit”
  34. 34. Rule 9: Narrow ChannelsNarrow 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 other vessels.– Crossing vessels shall not impede other vessels.
  35. 35. Rule 10: Traffic Separation Schemes Traffic Separation schemes my be adopted by the IMO for the purpose of these Rules.– 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.

Vessels in Sight of One Another Rule 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.
  42. 42. Rules 16/17: Action by Give-way and Stand-on VesselsGive-way: Every vessel which is directed to keep out of the way of another vessel shall, so far as possible, take early and substantial action to keep well clear.Stand-on: Where one of two vessels is to keep out of the way the other vessel shall keep her course and speed.
