Part F of Colregs was introduced with an amendment on the 1st of January 2016, IMO Resolution A.1085(28).AnnexesAnnex I – Positioning and technical details of lights and shapesAnnex II – Additional signals for fishing vessels fishing in close proximityAnnex III – Technical details of sounds signal appliancesAnnex IV – Distress signals, which lists the signals indicating distress and need of assistance.

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

I still remember the condition that was put by our first chief officer for us to enter wheelhouse and keep a watch with him. The condition was that we should know each rule of the road word by word. 18 years later, while writing this post I realize how appropriate his condition was.When it comes to navigation and watch keeping, to be crystal clear about COLREGS is undoubtably the priority. It takes several watches to be kept under the guidance of an officer to be clear about these rules.Problem is that we have nowadays moved from having a trainer to self training. Officers on board a ship are overloaded with their own work and so do not have time to train their juniors. In these cases, junior officers have to work on self training.In this post we will discuss in detail 8 rules every watch keeper must know. But before we move to the rules, we must know the sections in which COLREGS are divided. This is important because not all the rules are applicable in all the situations. For example rules under Part B, Section II are only applicable when you can visually see the other vessel. So we should know which rule is applicable under which condition.Sections and parts of ColregRules of the road are divided into Five parts. These arePart A: GeneralPart B: Steering and sailing rulesPart C: Light and shapesPart D: Light and sound signalsPart E: ExceptionsRecently in January 2016, there is another part (Part F) that has been added in the COLREG. This part deal with the verification of compliance which is not directly related to the seafarers.Rules of part B are further divided into 3 parts based upon the state of visibility.While all the rules are important, rules under part B (Steering and sailing rules) are the one that each seafarer must know at all the times. Here We will discuss some of the rulesRule 5: Look outIf I want my ship staff to follow only one rule, I would ask them to follow rule number 5. In my opinion this is the most important rule in the entire COLREG. All other rules are based on the fact that we are aware of our surrounding. But if we fail to keep a proper look out, we would not be able to apply other rules too.All this rule asks the watch keepers is to be vigilent by keeping their eyes and ear open. It emphasizes on three thingsBy sight and hearing. Which off course means that watch keeper need to keep look out not only by sight but also by hearing. By hearing means continuously listening to VHF and distress frequencies as well as any

What is the issue? In busy and restricted waterways, large vessels use sound signals to notify nearby boats of their intentions.Why address this? Sound signals are used to signal intentions on the waterways like an automobile's turn light indicators on the highways. All boaters should know proper sound signals, especially those boaters operating near commercial vessel traffic. If you are unaware of the signal communications it may become problematic and place your vessel and surrounding craft in jeopardy.How to address this? The following regulations are for vessels operating in the British Isles and covered by the The Merchant Shipping (Distress Signals and Prevention of Collisions) Regulations 1996 November 2003 - see Rules 34/35 extract . These are the same ones agreed to internationally and used on the high seas. Unfortunately some countries may have different inland water regulations, for example in the United States of America for instance, they reverse the port and starboard signals and have different overtaking signals. These are noted by dashed magenta lines found on many charts and labelled COLREGS DEMARCATION LINES which are the boundaries of restricted-navigation zones. To seaward of these lines, or where the lines do not exist, a skipper must follow the International rules - more formally known as the 1972 International Regulations for Preventing Collisions at Sea (72 COLREGS). Where these lines exist, and inshore of them, a skipper must use the specific Inland Waterway Rules.REQUIRED SIGNALING EQUIPMENTRule 33, equipment for sound signals, specify three devices used for sound signalling. A compressed air 'Air horn' is vital to the safety of a vesselPhoto: Courtesy of Lauzas These are a gong, a bell and a whistle that need to comply with the technical details for sound signal appliances set out in Annex III of the COLREGs:• A vessel of 12 metres or more in length shall be provided with a whistle• A vessel of 20 metres or more in length shall, in addition, be provided with a bell• A vessel of 100 metres or more in length shall, in addition, be provided with a gongThe rules do not oblige a vessel of less than 12 metres in length to carry a specially prescribed sound-signalling appliance. It states that it must have the means to produce some type of sound. The prudent mariner should subscribe to the rules and carry an appropriate horn, even if it's only a portable air horn priced under
