Rules of The Road Purpose and Scope
Agenda This section of instruction will cover the Rules of the Road, as published in the Navigation Rules (COMDTINST M16672.2D)
References COMDTINST M16672.2D Referred to by mariners as the “Rules of the Road”
Navigation Rules Purpose and Scope AGENDA: Purpose and Scope Principles of Maritime Law Rule #1 Applicability Rule #2 Rule of Good Seamanship Rule #3 General Definitions Applicable reading: USCG pp. 1-11. The most important thing to remember about the rules of the road is what they don’t do: the rules are not intended to be used to determine blame after a collision has occurred. They are intended to prevent the collisions in the first place. Hence their full name: Regulations for the Avoidance of Collisions at Sea How? = The rules are designed to state who should take action first to avoid a collision. They also establish ways for sailors who speak hundreds of different languages to speak to each other. In 1940, Captain Raymond Farwell said that “the rules, if implicitly obeyed, are practically collision-proof.”
Purpose of Scope of the Rules of the Road Sources: 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 waters NOTE: Navigation Rules have the force of law. History: Prior to the rules, each country had its own rules International Maritime Organization (IMO) Met in 1972 with representatives from 52 nations International Regulations for the Prevention of Collisions at Sea (COLREGS) Principles: 1. NavRules apply based upon a vessel’s location COLREGS line of demarcation territorial waters National/International Rules 2. NavRules have the force of law, they are mandatory Issue of Jurisdiction - US Federal Court 3. Obedience must be timely and positive Incremental course changes 4. NavRules apply to all vessels every description of watercraft Navy and Coast Guard vessels also fall under the Rules Contrast with” The king can do no wrong” theory
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.” INLAND/INTERNATIONAL – the Line of Demarkation, shown on this chart as a pink line, will tell you when international rules of the road are observed.
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 The rules must be obeyed, but they must not be blindly obeyed at the expense of good seamanship. The rules give you no excuse for hitting someone. Rule of Good Seamanship General Prudential Rule Special Situations Rules don’t cover every possible scenario: Ships operating in reverse (TR and LTG collision) Ships that are adrift There is no comprehensive list of IF…THEN’s In Extremis Literally: “at the point of death” or collision imminent Collision can be avoided only by action of both vessels It means one or both of the vessels failed to take the 1st line of preventive measures.
Special Situations (not covered by the Rules)
What is Good Seamanship? A. Turn around and go the other way. B. Speed up and pass vessel B on her starboard side. C. Overtake Vessel B on her port side after signaling. D. Slow down and stay behind Vessel B.
Rule 3: General Definitions Vessel Power driven vessel Sailing vessel Underway Making way Not making way Special Conditions Vessel engaged in fishing Not under command Restricted in ability to maneuver Constrained by draft (int’l rules only) Vessel - every description of watercraft (non-displacement craft, seaplanes) that are used or capable of being used as a means of transportation. Inner-tubes - no; sailboards - yes human/animal powered vessels are not covered under the rules - use Rule #2 (Good seamanship) - still don’t hit them Power- driven vessel - any vessel propelled by machinery Sailing vessel - any vessel under sail (not using engines for propulsion) See ROR for remaining definitions.
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 WIG “Power driven vessel”
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.
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
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
Rule 3: Definitions Vessel 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
Rule 3: Definitions Restricted Visibility
Rule 3: Definitions Restricted Visibility Fog Falling snow Heavy Rainstorms Sand storms Similar circumstances
Rule 3: Definitions WIG 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. This is the latest addition to the NAVRULES. Unless you have the newest version of COLREGS (D or greater) you will not find this vessel defined in your book.
Rule 4: Application Defines the application of rules 5-10 These rules apply in ANY visibility Yep. That’s all rule 4 says.
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 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 Good rule of thumb: you should be able to stop in half the distance of your visible horizon
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 3 most important pieces of information to an OOD Bearing Drift Target Angle Course/Speed
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 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 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 Schemes 4. AVOID ANCHORING 1. PROCEED IN APPROPRIATE LANE 3. ENTER @ SMALL ANGLE 2. CROSS AT RIGHT ANGLES
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 should not pretend they don’t see the other vessel to avoid compliance.
Vessels in Sight of One Another Rule 12: Sailing Vessels Applies to sailing vessels under sail. If the sailing vessel is using an engine, it becomes a power driven vessel
Vessels in Sight of One Another Rule 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. Overtaking is defined as a vessel that is 22.5 degrees abaft the beam. All other vessels are overtaking!
Vessels in Sight of One Another Rule 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. This rule does not apply to vessels on (or near) reciprocal courses that are not in danger of colliding. 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 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. Point out that the corresponding running lights will help you at night. If you see red, it’s your job to stop.
Rule 15 (cont) Crossing Situation Give-way Stand-on
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 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 Vessel being Overtaken Vessel Not under command Restricted in ability to maneuver Vessel Constrained by draft Vessel engaged in Fishing Sailing vessels Power driven vessels Seaplanes WIG Stay out of the way of: Use the pneumonic –O No Real Concern For Salty Pickle Sauced Weenies A WIG craft shall, when taking off, landing and in flight near the surface, keep well clear of all other vessels and avoid impeding their navigation; Note that there is no such thing as a vessel constrained by her draft in INLAND rules
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.
Rules 20: Application of Lights and Dayshapes Sunset to Sunrise Restricted Visibility DAYSHAPES Sunrise to Sunset
Rules 21-24: Lights and Dayshapes AGENDA: Rule #21 Definitions Rule #22 Visibility of Lights Rule #23 Power Driven Vessels Underway Rule #24 Towing and Pushing Applicable reading: USCG pp. 38-70. The most important thing to remember about the rules of the road is what they don’t do: the rules are not intended to be used to determine blame after a collision has occurred. They are intended to prevent the collisions in the first place. Hence: full name: Regulations for the Avoidance of Collisions at Sea The rules are designed to state who should take action first to avoid a collision. They also establish ways for sailors who speak hundreds of different languages to speak to each other.
Purpose of Lights and Shapes To indicate hierarchy under the steering and sailing rules. To aid in the determination of stand on/give way status. To indicate to an approaching vessel information not readily available by visual observation. To identify the occupation of certain vessels. To aid in the determination of angle on the bow (AOB) and course.
