COLREGs Part C: Lights and Shapes — Understanding the Visual Language of Ships at Sea

-
Image
  Rules 20–31 | The lights and shapes every seafarer must recognise At sea, navigation does not stop when daylight disappears. In darkness, restricted visibility and busy traffic conditions, a vessel communicates important information through navigation lights and day shapes . These visual signals help other vessels understand what type of vessel they are observing, whether it is underway, anchored, towing, fishing, restricted in its ability to manoeuvre or constrained by draught. This is the purpose of Part C of the International Regulations for Preventing Collisions at Sea (COLREGs) . Part C contains Rules 20–31 , covering lights and shapes. The International Maritime Organization (IMO) identifies Part C as the section dealing with lights and shapes, supported by technical requirements in Annex I. For a deck officer keeping a night watch, recognising a vessel's lights is not simply a matter of memorising colours. The colour, position, number, arrangement, relative bearing and ...

COLREGs Part B: Steering and Sailing

Image
  The Rules That Guide Ships Away From Collision The International Regulations for Preventing Collisions at Sea (COLREGs) provide the international framework for preventing collisions between vessels. Part B — Steering and Sailing is at the heart of this framework, covering Rules 4–19 . It explains how vessels should conduct themselves in different visibility conditions, when vessels are in sight of one another, and when visibility is restricted. For a deck officer, Part B is not simply a collection of rules to memorize. It provides a structured way to observe traffic, assess collision risk, determine responsibilities, and take appropriate action. CONDUCT IN ANY CONDITION OF VISIBILITY Rules 4–10: The Foundation of Collision Avoidance The first section of Part B contains Rules 4–10 and applies in any condition of visibility . These rules establish fundamental principles that every vessel must follow regardless of whether navigation takes place in clear weather, darkness, rain,...

COLREGs – Section A: The Foundation of Safe Navigation

-
Image
  Rules 1–3 Every Seafarer Should Understand The International Regulations for Preventing Collisions at Sea (COLREGs) provide the fundamental rules that govern how vessels navigate in relation to one another. Before learning who should give way, which vessel should keep course and speed, or what lights and shapes must be displayed, seafarers must first understand Part A – General . Part A contains Rules 1, 2 and 3 . These three rules establish the scope of the regulations, the responsibility of the master and crew, and the important definitions used throughout COLREGs. Although these rules appear simple, they form the foundation for correctly interpreting the rest of the regulations. RULE 1 — APPLICATION Rule 1 explains where and to whom the COLREGs apply . The regulations apply to vessels on the high seas and in waters connected with the high seas that are navigable by seagoing vessels. This is important because COLREGs are intended to provide a consistent set of collision-pr...

SOLAS: SAFETY OF LIFE AT SEA

Image
  The International Framework That Keeps Ships and Seafarers Safe The sea is one of the world's most important transportation routes, but operating a ship involves complex risks. Fire, collision, grounding, flooding, machinery failure, cargo hazards, severe weather, and emergencies can threaten the lives of everyone onboard. To establish internationally agreed safety standards, the maritime industry relies on SOLAS — the International Convention for the Safety of Life at Sea . SOLAS establishes minimum requirements for the construction, equipment, and operation of ships , helping ensure that vessels are designed and operated with safety at the centre. For seafarers, SOLAS is not simply a convention found in a training manual. Its requirements influence everyday activities on board—from navigation and firefighting to life-saving appliances, radio communications, cargo operations, and emergency preparedness. What Is SOLAS? SOLAS stands for the International Convention for the Sa...
