Colregs: International regulations for preventing collisions at sea 1972 are a set of rules published by the IMO (International maritime organization) to prevent collisions at sea. Colreg 1972 is the final stage of rules agreed upon a convention in London in 1972.Surely one of the most important innovations adopted in 1972 was the introduction of the traffic separation scheme, analyzed in the details in RULE 10, where it indicated all the requirements that a power-driven vessel and vessels must adopt during their transit. The COLREGs are divided into 41 rules, each being part of a specific part. Part A – General; Part B – Steering and Sailing; Part C – Lights and Shapes; Part D – Sound and Light signals; Part E – Exemptions; and Part F – Verifying compliance with the provisions of the Convention. In the remaining part of the conventions, we find the annexes that detail the characteristics of the lights and shape, their positioning, and sound signaling appliance.Part A (General Rule 1-3)Colregs part A contains the general provision of the Convention and the correct way to interpret and use the Colreg. It is part of part A of Colreg, the rule 1,2,3 that respectively indicate the applications, responsibilities, and definitions.Part B Steering and Sailing (Rules 4-19)Part B of COLREGs is divided into two parts: Section 1 applies to any visibility conditions. Section II – Conduct of vessels in sight of one another (Rules 11-18), and Section III – Conduct vessels in restricted visibility (Rule 19).Section I

(b) A vessel restricted in her ability to manoeuvre, except a vessel engaged in minesweeping operations, shall exhibit: (i) three all-round lights in a vertical line where they can best be seen. The highest and lowest of these lights shall be red and the middle light shall be white; (ii) three shapes in a vertical line where they can best be seen. The highest and lowest of these shapes shall be balls and the middle one a diamond; (iii) when making way through the water, masthead lights, sidelights and a sternlight, in addition to the lights prescribed in sub-paragraph (i); (iv) when at anchor, in addition to the lights or shapes prescribed in sub-paragraphs (i) and (ii), the light, lights or shape prescribed in Rule 30.
