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.

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.

Purpose of Scope of the Rules of the Road

Nav Rules apply based upon a vessel’s location.COLREGS Line of Demarcation

Rule 1(a): Applicability

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

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

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

Special ConditionsVessel engaged in fishing

Not under command

Restricted in ability to maneuver

Constrained by draft (int’l rules only)

Vessel

Power driven vessel

Sailing vessel

Underway

Making way

Not making way

Vessel: includes every description of water craft used or capable of being used as a means on transportation on water.

Rule 3: DefinitionsVessel

• Includes:– Power-driven vessels– Sailboats– Seaplanes– Non-displacement craft– WIG

• “Power driven vessel”

Vessel engaged in fishing means any vessel fishing with nets, lines, trawls or other fishing apparatus which restrict maneuverability.

Rule 3: DefinitionsVessel engaged in fishing

• Does NOT include:– Vessel engaged in trolling.

Vessel not under command means a vessel which through some exceptional circumstances is unable to maneuver to comply with the Rules.

Rule 3: DefinitionsVessel not under command

• Examples:– Propulsion casualty– Steering casualty

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.

Rule 3: DefinitionsVessel restricted in ability to maneuver

• Examples:– Laying navaids– Dredging/Surveying– UNREP– Flight Ops– Mineclearance Ops

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: DefinitionsVessel constrained by draft

Rule 3: DefinitionsUnderway, Not-underway

Rule 3: DefinitionsRestricted Visibility

Rule 3: DefinitionsRestricted Visibility

Fog

Falling snow

Heavy Rainstorms

Sand storms

Similar circumstances

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.

Rule 3: DefinitionsWIG

Defines the application of rules 5-10

These rules apply in ANY visibility

Rule 4: Application

Rule 5: Look-out

Application (Rule 4) - Any condition of visibility

Look-out (Rule 5)Maintain Proper LookoutUse 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 SpeedState 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

Risk of Collision (Rule 7)Use all available means to determineEarly use of RADARDon’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

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

2. CROSS AT RIGHT ANGLES3. ENTER @ SMALL ANGLE1. PROCEED IN APPROPRIATE LANE4. AVOID ANCHORING

Rule 10: Traffic Separation Schemes

Application rule Rules 12-18

Applies to all vessels in sight of one another

Rule 11:Conduct of Vessels

in Sight of One Another

Vessels in Sight of One AnotherRule 12: Sailing Vessels

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 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 AnotherRule 15: Crossing Situation

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


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)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 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.
