Navigation—buoys, marks and beacons
Marine Navigation Buoys and Channel Markers [ Lateral A ] system has red flat-topped cairns to port on entering, and green conical marks to starboard. Cardinal Buoys are pointing that the deepest water is appearing on the page of the name for the sign. Thus, the IALA Maritime Buoyage System will continue to help all Mariners, navigating anywhere in the world, to fix their position and avoid dangers without fear of ambiguity, now and for the years to come.
Long spinner lasting not briefly than 2 seconds directly after VQ 6 or Q 6 is characteristic of the ‘S’ quadrant. The buoy where the channels divide would be a red cylindrical can or pillar with a cylindrical top mark. Safe water marks show that there is navigable water all around the mark. Special marks are not intended primarily as navigation marks.
Check the maritime chart if the direction of buoyage is not obvious and will be marked using an [ arrow with two dots ]. In the absence of anything better, the Geneva rules were adopted with or without variation to suit local conditions and the equipment available.
The IALA maritime buoyage system, where the marker colour coding scheme of red for port left and green for starboard right was implemented worldwide. Continuity and harmonization of Aids to Navigation Marking is to be encouraged by all competent maritime authorities. In ‘B Region’ applying colours is reverse: The colours of the cardinal buoys can be hard to identify when weed or bird fouling buoyagee, and recognizing the colour of the buoy as yellow signifies north or west and a black buoy as south or east, while identifying the top mark positively, ensures that no fouling confuses the issue.
The front lead has its apex pointing up and the rear or back lead has its apex pointing down. The top marks of cardinal buoys consist of the combination of two black cones, mounted one above the other on the top of the buoy with the following combinations: It provided for the use of the colour red on port hand marks and largely reserved the colour green for wreck marking.
A [ hand bearing compass ] sighted along the expected bearing of the buoy may make it easier to find.
Vessels must not enter or depart the port or harbour area when the port traffic signal lights are flashing. At night, each type of cardinal mark has a flashing white light with different groupings of flashes continuous, or groups of 3, 6 or 9.

VQ or Q continuous. These were called System A and System B, respectively. They have blue and yellow vertical stripes and are a pillar or spar shape with a yellow cross as the top mark.

The colours used in the Cardinal system are yellow and black. Around the middle would be a green band. The most significant changes in the revision are the inclusion of aids to navigation used sysrem marking recommended by IALA that are additional to the floating buoyage system previously included. The IALA chose the two systems in order to keep the number of changes to existing systems to a minimum and to avoid major conflict.
The light characteristic of each mark is noted on the chart of the area and in sailing directions. The duplicating sign should stand so a long way until the information about new danger is announced in the way being enough. Terms used on charts are:.
Where leads are used to mark the middle of larger shipping channels small vessels buoyag travel on the starboard side of the channel to keep clear of large ships. Further information Buoys, marks and beacons factsheet PDF, 2.
New danger marks were introduced in and are used as emergency marks for recent wrecks or new hazards which do not appear on nautical charts. An isolated danger can be a rock or a sunken boat.
