BUOY

What comes to your mind when you heard of buoy?
What its function?
A buoy is a nautical floating device anchored into the sea to mark a channel, signal etc.

It is used in navigation of vessels, indication of location of channels and warning of hazards for mariners.




There are two general system of buoyage.

  1. Lateral: In this system, the location of each buoy indicates the direction of the danger relative to the route that is to be followed.
  2. Cardinal system: The location of each buoy indicates the approximate true bearing of safe water from danger it marks.

The
re are four types of buoys we might always encountered.
  • Red
  • Green
  • Red and green horizontally
  • Red and white vertically stripped
  1.  Green Buoy: It marks the port left side of a channel when entering a smaller body of water (Returning). This shows which side is safest to travel.
  2.  Red Buoy: It marks the right side while travelling.
  3. Red and Green horizontally Stripped Buoy: These are junction buoys which also might indicate an obstruction with two different ways around the obstruction. These buoys will indicate the preferred and secondary channel to be taken.
  4. Red and White Vertically Stripped: They are safe water or mid channel buoys indicating good depth of water. They can either be at left when returning or leaving.
