International regulations known as Colregs and navigation lights and shapes. Sailing rules of the road international rules of the road at sea or IRPCS rules and sailboat racing rules tutorial. A powerboat is about to cross paths with a sailboat under sail. What should the powerboat do? In the navigation rules what is the duty of the stand on boat? National governments and local authorities impose their own regulations covering harbours, rivers, or inland waterways in addition to the Col Regs with details being found in jrpcs pilot books.
Have a ready reference to the colregs available in the cockpit so that any unfamiliar situation can be checked. Along with these maritime navigation rules, the skipper of a sailing vessel fitted with a motor should be aware of the diverse rules that apply when sailing and when motoring. Sailors refer to the ‘marine navigation rules of the road’, which are the marine navigation rules they are most familiar with and apply to their everyday use in confined channels where the application of the rules prevents a collision with other vessels.
The purpose of these rules of the road when sailing, is to prevent confusion when vessels are approaching, given that ships and boats are free to move in any chosen direction. Large ships follow well-charted sea routes, but smaller sailing vessels have greater freedom in movement and do cross these routes.
The colregs rules of the road are specific as to the duties that each vessel must observe. In situations in which two vessels are approaching each other, the rules designate one as the give-way vesselwhose duty is to take avoiding action and the other, the stand-on vesselwhose duty is to take right of way.
The give-way vessel must take positive action in plenty of time to avoid a collision, and course alteration or change in speed should be obvious to the other vessel.
The master of each vessel has an expectation that the other will act according to the maritime navigation rules, but should be prepared to take avoiding action if necessary.
Confusion can arise trying to judge which boat is the stand-on or give-way vessel in a situation. When [ under power] it is easily understood by referencing the sectors of the [ basic navigation lights ]. Under sail and sailing to windward on port tack, it rulfs be difficult to decide, especially at night, if a boat to windward and running downwind is on port or starboard tack.
If on port tack your boat has right of way and should stand on, but if the other boat is on [ starboard tack ]it has right of way requiring your boat to keep clear.
When a powerboat is about to cross paths with a sailboat under sail, the powerboat is to give way in all circumstances. Where there is any doubt, assume that your boat has to give way and be ready to take evasive action early before a danger of collision arises. Gules include keeping a constant lookout at ircps times, proceeding at a safe speed, and rulez close to navigational hazards taking account of the sea state and wind.
Lookouts should use a clock-notation system to tell irps skipper where an approaching vessel is in relation to the yacht and an estimate of the distance of the ship and its direction of travel. Fishing vessels are unpredictable as they move in all directions. The ColRegs acknowledge this and the advice is to keep clear of vessels identified by the [ appropriate lights ] or shapes, as fishing vessels.
Commercial shipping should be treated with great caution. Theoretically, they are required to give way to sailing vessels.
Rules of the Road – The International Regulations for the Prevention of Collision at Sea
Usually they are on autopilot in open waters and restricted in narrow channels, so demonstrate your intentions and do not insist on right of way. As two powered vessels meet and are approaching each other head-on, each should alter course to starboard, so that they pass each other port-to-port.
Remember the rule by this saying, ‘If I am on the right, I am in the right. Racing rules are formed from rules relating to sailing vessels. Therefore, with two boats on different tacksthe vessel on a port tack with the wind blowing over its port side must keep out of the way of one on a starboard tack with the wind over its starboard side.
When two boats are on the [same tack,] the windward boat the one closest to wind must keep out of the way of the vessel to leeward. Any vessel on a port tack and unsure of what tack another vessel is on, must keep out of its way.
IRPCS Training Aids:
The windward side irrpcs, with regard to racing rules, is determined to be the opposite side to that on which the mainsail is carried. Overtaking rules are the same as for powered vessels and are designed to keep the overtaking vessel away from the vessel being overtaken. Yacht crews may be small and inexperienced, but it is essential that a lookout is kept at all times. Instruct the crew to alert the skipper whenever an approaching vessel is seen.
When your boat is the give-way vessel, or the situation is uncertain, take evasive action well in advance prior to a potential collision. When irpcx a crossing situation with a large ship, there may be uncertainty as to whether your boat and the other boat are on a collision course. Make use of a [ hand bearing compass ] to take bearings of the approaching ship at frequent intervals.
If the bearing remains the identical, then each are on a collision course and immediate action must be taken. An alternative to taking compass bearings, use a part of the boat, such as a stanchion, as a reference point. The boat is on a collision course if the other vessel stays in line with it; if it moves forward of the reference point it will pass ahead of your boat, if it falls back your boat will pass ahead of it.

Having decided to take avoiding action, make a significant course change indicating that your intentions are obvious to the other vessel. Avoid crossing the bows of another craft which may be moving much faster than thought.
If possible, alter course to pass astern of ryles other vessel or if in doubt, turn onto a parallel course in the same direction as the other vessel and wait for it to pass. The IRPCS rules on navigation lights state that under power, use another power boat’s light sectors to decide when to give way or stand-on. In the white or red sectors, give way; in the green sector, stand-on.
Between the traffic lanes are separation ryles which are restricted to fishing vessels, ships in a state of emergency, and those iirpcs the lanes. Vessels that are crossing a separation zone must do so at right angles. Entering a traffic lane should be done at the ends of the lane where possible, or at a shallow angle so as to blend into the traffic flow.
Local traffic use the inshore zones and keep out of the lanes.
If crossing a traffic-separation scheme, it is important that it is done as quickly as possible. Steer a course at right angles to the lane while rule adjusting the course to allow for any sideways tidal effect, as this increases the time that it takes to cross. In rukes navigable channels, it may be impossible to make large course changes without the prospect of going aground.
Commercial vessels are constrained by their draft and when in the channels, yachts should keep to the periphery of the channel.
The common ‘rule of the road’ is that traffic keeps to starboard the right while navigating channels. In a channel with blind bendsanother rule is that the appropriate sound signals should be sounded prior to engaging in specific manoeuvres. In clear visibility, irpcs sound signals indicate that a vessel is carrying out a manoeuvre. Under power and in sight of each other, when one boat is altering course, it indicates its intentions by horn signals. When at night, an all-round white light is flashed for the appropriate number of times.
Vessels must use [ shapes ] during the day to make identification easier. An inverted cone shape on the forestay indicates that a yacht is motor-sailing, and a ball shape in the rigging indicates it iirpcs at anchor. A vessel when approaching a blind bend sounds one prolonged blast and another vessel approaching the bend in the opposite direction, sounds a prolonged blast in reply.
The signal is acknowledged by four blasts – one prolonged, one short, one prolonged and one short meaning ‘I agree and will keep my course. When visibility is restricted rulex, there are of a number sound signals that must be understood. The principal maritime navigation rules governing a motor sailing vessel are:. If you are at anchor in an area where a risk iepcs collision exists, ring a bell or strike a gong for rupes seconds once a minute.

IRPCS Marine Navigation Rules of the Road Sailors refer to the ‘marine navigation rules of the road’, which are the marine navigation rules they are most familiar with and apply to their everyday use in confined channels where the application of the rules prevents a collision with other vessels. Keeping a Lookout Responsibilities include keeping a constant lookout at all times, proceeding at a safe speed, and when close to ripcs hazards taking account of the sea state and wind.
A sailing boat underway should keep clear of: A vessel not under command A irpcw restricted in its ability to manoeuvre Rles fishing irpds A vessel constrained by its draught Fishing vessels are unpredictable as they move in all directions.
Collision Avoidance Basic Rules As two powered vessels meet and are approaching each other head-on, each should alter course to starboard, so that they pass each other port-to-port. Taking Evasive Action Yacht crews may be small and inexperienced, but it is essential that a lookout is kept at all times. Assessing a Likely Collision Make use of a [ hand bearing compass ] to take bearings of the approaching ship at frequent intervals. Navigation Light Sectors The IRPCS rupes on navigation lights state that under power, use another power boat’s light sectors to decide when to iepcs way or stand-on.
Traffic Separation Zones [ Traffic separation schemes ] in busy shipping areas are in position to keep local traffic separate from through traffic and are split into two lanes.
