Lighthouse - Lighthouse - Buoys: Buoys are used to mark safe channels, important reference points, approaches to harbours, isolated dangers and wrecks, and areas of special significance. A north cardinal buoy is located so that the safest water exists to the north of it. The buoyage system used in Canada corresponds to the International Association of marine aids to navigation Lighthouse Authorities (IALA) Maritime Buoyage System which has been adopted by all major maritime nations in the world. Lateral buoys indicate the side on which they may be safely passed. Be sure you know what the ‘diver down’ flags look like. Flash characteristics are shown below (if equipped). R means a red light.

Cardinal buoys indicate the location of the safest or deepest water by reference to the cardinal points of the compass. A very quick flash can also be used — 9 flashes every 10 seconds. Lights of different colours are used to assist recognition of the marks in the Canadian Aids to Navigation system. Light Characteristics 1. West Cardinal Buoy. A very quick flashing white light in which a group of 9 flashes is regularly repeated 6 times per minute (every 10 seconds). Safe water mark: Sometimes called a ‘Fairway Buoy’ or ‘Sea Buoy’ they are striped vertically red and white, have a single ball on top and will flash a single long white flash every ten seconds. For example, a North Cardinal Buoy indicates that safe water lies to the North of the buoy. A keep-out buoy is coloured white and has an orange diamond containing an orange cross on two opposite sides and two orange horizontal bands, one above and one below the diamond symbols. Many buoys are fitted with radar reflectors to improve their visibility on the radar screen. A white light in which a group of 6 very quick flashes is followed by a single long flash, the whole sequence being regularly repeated 6 times per minute (every 10 seconds). North buoys flash at the rate of 1 per second or 60 per minute.

These can be used to relay a host of information or provide warnings of impending danger. ODAS and Diving buoys are governed by the Canada Shipping Act 2001, Collision Regulations. A port bifurcation buoy marks the point where a channel divides when viewed from a vessel proceeding in the upstream direction and indicates that the preferred or main channel is on the starboard (right) side of the buoy. Description. The arrows always point to the black sections - in this case the upper and lower sections; East is at “Three o’clock” on the Compass - … pass north of a North Mark). Finally, special buoys serve a variety of purposes. As a way of remembering the light flash characters of the East, South and West Cardinal buoys, the number of flashes in each group for these lights is the same as the figure on the clock face in the corresponding compass direction (e.g. It displays identification letter(s) and, if it carries a light, the light is white and is a quick flashing (Q)1s or very quick flashing (VQ)5s light, and. The use of such buoys is generally restricted to coastal waters where there is sufficient buoy motion to activate the sound device and where there is a requirement for an audio signal to enable location of the buoy under low visibility conditions. if it carries a light, the light is green and is a flashing (Fl)4s or quick flashing (Q)1s light. Collision Regulations pertaining to sound and ligh... Boating - Provisions of the Collision Regulations ...

West cardinal buoy. if it carries a light, the light is green and is a composite group flashing Fl(2+1)6s or Fl(2+1)10s light, if it does not carry a light, the top of the buoy is flat, and. An east cardinal buoy indicates safe water to the east. Fl means flashing. Bifurcation buoys are similarly affected in that the predominant colour of starboard bifurcation buoys is red in Region “B” and green in Region “A” and that of port bifurcation buoys is green in Region “B” and red in Region “A”. East Cardinal White light, Very Quick or Quick Flashing 3 every 5 or 10 seconds, Pass to the East side of this buoy. A mooring buoy is used for mooring or securing a vessel, seaplane, etc. There are 4 main sections: 1. On an east cardinal buoy the apexes point up and down, matching the black at the top and bottom of the buoy. All other types of buoys are identified by letters only. Some are cautionary buoys to mark firing range or seaplane bases, while others gather weather information, locate prohibited areas or mark designated mooring areas. An ODAS buoy shall not exhibit a shape that conflicts with any navigational mark. A swimming buoy marks the perimetre of a swimming area. The information words or symbols are black and are placed within the white face of the square symbol. Fairway buoy. A flat top or cylindrical (can) shape indicates that the buoy is marking the port (left) side of the channel or the location of a danger which must be kept on the vessel’s port (left) side when proceeding upstream. if it carries a topmark, the topmark is two black cones, one above the other, point to point.

The lights on all cardinal buoys will be white in colour, (if the buoy is so equipped). A hazard buoy marks random hazards such as rocks, shoals or turbulent waters located outside the main channel. If you think about a clock face and the position of 3 o’clock, the east cardinal is in the east position on a clock face and therefore extremely easy to remember the light characteristics, 3 quick flashes. if it carries a topmark, the topmark is a single yellow “X” shape. (0.3+0.7)2+ (0.3+7.7)=10 sec.

A new danger may be marked by a RACON coded Morse “D”. An east cardinal buoy is located so that the safest water exists to the east of it. For all buoys other than special buoys the colour of the retroreflective material is the same as that of the light which would be appropriate for each buoy. An ODAS buoy is coloured yellow, displays identification letter(s) and, if it carries a light, the light is yellow and is a group flashing light of 5 flashes every 20 seconds, Fl(5)20s, and. A very quick flash can also be used — 3 flashes every 5 seconds.

The buoy light characteristics for all buoys in the Canadian Aids to Navigation system shall conform to the “Specifications for Buoy Light Characteristics” detailed in table below.
