Light positions are a better tipoff to the bow direction and how far from the bow the sidelights might be. Remember - on a large vessel the sidelights may not be at the bow or even close to it. USCG Inland Rules allow for a second all-around white light on large vessels on the Great Lakes instead of a second masthead light. Fishing BoatsFishing boats engaged in fishing will have more complex light displays. When they aren't fishing, they will show lights like any power vessel, but Rule 26 spells out light combinations that vary by the fishing activity being done.In general: Boats which are Trawling but not making headway will display a green all-around light over a white all-around light, and a masthead light aft of these lights. Boats making headway while trawling will show these lights, plus sidelights and a stern light. A vessel fishing other than trawling will show a red all-around light over a white all-around light. When making way they will also show sidelights and a stern light. If a vessel has gear more than 150 meters away from the boat, it will show a second all around light in the direction of the gear.The best rule is to give fishing boats as wide a berth as you can at night. They're easy to pick out if you check the top light configurations but their course may be difficult to predict. Towing and PushingTowed vessels can be the most dangerous to cross, but they have the most lights to tell you what is happening. Refer to COLREGS or the USCG Rules of the Road Rule 24 for all combinationsYou can pick a tow/push vessel out with the following lights: Two or three masthead lights in a vertical line. Three masthead lights shows a tow over. rule 6 colregs,colregs rule 5,colregs in depth,collision regulations,colregs rules of the road,ship collision regulations,marine,rule 5,rule 6,rule 6 safe sp Boating Rules of the Road – International ColRegs; ColRegs when sailing single handed; ColRegs Nav Lights Shapes, Rules Of The Road and IALA Buoys Apps; Top Tips ForCOLREGS - Rules of the Road - Seably
Visibility, all other lights must be visible for two nautical miles.Optional masthead lights - any vessel under sail may display a red light over a green light at the masthead with sidelights and stern light. The red over green may NOT be displayed with a masthead tricolor light. It's one set or the other. Lights When MotoringFor all navigational purposes a sailboat under power is considered a power boat. This includes motor sailing - if the engine is on and providing propulsion you are on a power boat, even if the sails are up. This applies to navigation lighting, sound signals in fog and limited visibility, and rights of way. Sailboats under 50 meters under power need to show: A masthead lightSidelights Stern light A power-driven vessel under 23 feet (7 meters) that does not exceed seven knots of speed may display an all around white light, though sidelights should be used if available. What about the USCG (United States Coast Guard) Rules?The USCG has published its own "Rules of the Road" that are based on the COLREGS. In addition, it has rules for the "Inland Waterways" for rivers, inland lakes and the Great Lakes.The good news is this has no impact on what you have to do with your own boat.They mostly relate to lighting changes on towed vessels like barges and tugs. For example, a vessel towing or pushing another vessel in the ocean under COLREGS shows two masthead lights, sidelights and a stern light, whereas in Inland Waterways the towing or pushing vessel displays two yellow towing lights instead of a white stern light. If you sail on lakes, rivers or the Great Lakes where towed commercial traffic is common you should learn the inland lights, but coastal or ocean sailors will never see these.

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 anyAmazon.com: Colregs Rules Of The Road
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 underColregs Rules of the Road - OnboardOnline
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.

COLREGS - Rules of the Road (USCG)
When navigating at night, the lights on other boats are your first clue about the moving dangers around you. And your navigation lights are your first line of safety in avoiding collisions in the dark, and they tell others vessels what you are and what you are doing. The rules sound complex, but with a little understanding you can get the basics for any situation. So what are the basic navigation light rules? For most small vessels, motoring requires red and green (port and starboard) lights, and a white light visible in all directions around the boat. This is almost always a stern light and a masthead light on sailboats. Boats under sail require port and starboard lights, and a white stern light. Sailboats below sixty-five feet may show a tricolor light at the masthead instead of side and stern lights when sailing.That's it, in a nutshell. There's a little more to it, as the rules change with different sizes and there are some specifics about angles of display for the colors. Identifying other ships at sea requires more study, but the basics are the same. And it's not much trouble to make sure you've always got the proper lights on your vessel. On this page: What are the official COLREGS rules for your sailboat? What about the USCG (United States Coast Guard) Rules? Lighting at Anchor Identifying the Boats Around You What are the official COLREGS rules for your sailboat?The International Regulations for the Prevention of Collision at Sea, abbreviated "COLREGS" is very specific about the lights required, their shapes and sizes, and the distance they must be visible. For the smaller boat, the following definitions apply. Masthead Light - a white light placed centerline on the boat showing an arc of 225 degrees with 112.5 degrees either sideCOLREGS The Rules of the Road - PDFCOFFEE.COM
Of the front of the vessel. Sidelights - A red light on the port side and a green light on the starboard. They must show an arc of 112.5 degrees from centerline of the bow. Stern light - A white light on the stern of the boat showing an unbroken arc of 135 degrees from centerline of the vessel. All-round light - A light showing in an unbroken arc of 360 degrees. The good news is you need not measure these angles. Any properly installed USCG or COLREGS approved light which will cover the correct arcs. If you have to replace the original light from your boat, make sure it's with an approved replacement. Lights When SailingThe specific rules for a sailboat under sail are in COLREGS Rule 25 and vary slightly with the size of the boat. A sailboat powering is considered a power boat and falls under in Rule 23. Under 23 feet (7 meters) - side lights and a stern light, possible. If these lights can not be displayed a light must be kept at hand to help avoid a collision. This can be a bright flashlight. Over 23 feet - Side lights visible to one nautical mile and stern light visible for two. Less than 65 feet (20m) - Vessels under 65 feet may combine both sidelights into a single lantern on the bow. May show a tricolor light on the masthead instead of sidelights and a stern light. It's one or the other though, do not show these lights at the same time. Masthead light must be visible for three nautical miles, all other lights must have a two nautical mile visibility. Over 65 Feet - Side lights must be separated. May not show a masthead tricolor light. Masthead light must have five nautical mile. rule 6 colregs,colregs rule 5,colregs in depth,collision regulations,colregs rules of the road,ship collision regulations,marine,rule 5,rule 6,rule 6 safe spCOLREGS - Rules of the Road - Rule 13 Overtaking
