What is the definition of 'VESSEL RESTRICTED IN HER ABILITY TO MANEOUVRE' according to COLREGS 1972 Rule 3?

  • A vessel that is unable to maneuver due to engine failure.
  • A vessel restricted in her ability to maneuver as required by the rules and unable to keep out of the way of another vessel. (correct)
  • A vessel that has lost its navigational instruments.
  • A vessel that is moving faster than it should.

Which of the following activities would classify a vessel as 'Restricted in her ability to maneuver'?

Flashcards

Vessel Restricted in her Ability to Maneuver

A vessel that is restricted in its ability to maneuver and cannot keep out of the way of another vessel due to its limitations.

Vessel Constrained by her Draught

A vessel with a deep draft, making it difficult to navigate in areas with shallow water or narrow channels. This makes it challenging to deviate from its course.

Activities Restricting Maneuverability

Replenishment operations, launching torpedoes, or any other activity that restricts a vessel's ability to properly steer, maneuver, or respond quickly to avoid collisions.

Vessels Constrained by Draught Navigating Restrictions

A vessel that is required to deviate its course because of its deep draft and the limitations of waterways, such as narrow channels or areas with limited depth.

Power-driven Vessel Constrained by Draught

A power-driven vessel (like a ship or a boat) that is restricted in its ability to maneuver because of its deep draft (think of a large ship that can't navigate in shallow water).

Characteristics of Vessels Constrained by Draught

Due to restrictions imposed by their draft, these vessels are limited in their ability to alter their course or speed. This makes them more vulnerable to collisions and they need to be extra cautious while navigating.

Navigational Challenges for Restricted Vessels

Foggy conditions can create a situation where visibility is limited, making it difficult for vessels restricted in their ability to maneuver to navigate safely due to their limited ability to respond quickly to changes in the environment.

Replenishment Operations

The process of providing supplies to a vessel, such as food, fuel, or ammunition, while the vessel is anchored. This activity often restricts the vessel's ability to maneuver.

Study Notes

International Regulations for Preventing Collisions at Sea, 1972

  • COLREGS 1972 contains 6 parts (A-F) and 41 rules with 4 annexes
  • Objectives: explain COLREGS 1972, identify responsible parties, explain Rule 1, and define COLREGS terms

Application of COLREGS

  • COLREGS apply to all vessels in high seas and navigable waters connected therewith
  • Exception: areas within demarcation lines where Inland Rules apply
  • Special rules made by authorities or governments may apply in specific areas
  • COLREGS do not interfere with special rules made for roadsteads, harbors, rivers, lakes, or inland waterways

Definitions

  • "Vessel Restricted in Her Ability to Manoeuvre" (RAM): a vessel restricted in its ability to manoeuvre due to its work
  • Examples of Vessels RAM: laying or servicing navigation marks, dredging, surveying, underwater operations, replenishment, launching/recovery of aircraft, mine clearance, or towing operations
  • "Vessel Constrained by Her Draught": a power-driven vessel severely restricted in its ability to deviate from its course due to its draught in relation to available water depth and width
