  • Introduce the topic and purpose of Nav Aids.
  • Present the information.
  • Point out that these aids are typically self explanatory.
  • Just an example.
  • Being merged with the IALA-B system. Becomes official at the end of this year. Black buoys have been changed to green. Still usually found in pairs.
  • Present the point.

Buoyage Systems in the U.S. <ul><li>IALA (International Association of Lighthouse Authorities) </li></ul><ul><ul><li>IALA-A (Eastern Hemisphere) </li></ul></ul><ul><ul><li>IALA-B (Western Hemisphere) </li></ul></ul><ul><li>Intra-coastal Waterways </li></ul><ul><li>Uniform State Waterways </li></ul>“ Buoyage refers to all the different physical devices, buoys, lights, day boards that convey information to the mariner based upon colors, shapes and numbers.”
    17. 19. U.S ATONS: IALA-B System Western Hemisphere Lateral markers in the IALA-B system follow the 3R Rule : Red on Right when Returning upriver (or from sea)
    18. 20. IALA-B Markers Cans Cylindrical-shaped buoys are marked with green markings and odd numbers . They mark the left side of the channel as a boater enters from the open sea or heads upstream. Hint: “7Up” comes in a green can. Nuns Cone-shaped buoys are marked with red markings and even numbers . They mark the right side of the channel as a boater enters from the open sea or heads upstream. Hint: “V8” comes in a red bottle.
    19. 21. Other IALA-B Markers Lighted Buoys Buoys use lateral marker shapes, colors and numbers and have a matching colored light. Beacons, Day Boards and Daymarks Permanently placed signs attached to structures. Common daymarks are red triangles (equivalent to nuns) and green squares (equivalent to cans). These may also be lighted. Range Markers Found in pairs with one higher than the other. Indicate the center line of a channel by aligning both as you pass through the channel.
    20. 22. Preferred Channel Marks Junction markers indicate the preferred channel at points where the waterway splits or branches off in another direction
    21. 23. Reading A Chart The first marker seen entering from sea is the open, or safe water marker. The RW &quot;G&quot; means that it is a Red and White striped marker with, in this case, the letter &quot;G&quot; on it. or

    23. 27. Reading A Chart The next marker you see as you enter this waterway is G &quot;1&quot; Fl G 4 sec . This tells you it is Green , has the number 1 on it, and it Flashes Green once each 4 seconds .
    24. 28. Reading A Chart R N &quot;2&quot; plus the red symbol indicates a Red Nun buoy with the even number 2 on it. Conversely G C &quot;3&quot;, is a Green Can buoy with the odd number 3 on it.
    25. 29. Reading A Chart A junction marker referred to as RGN &quot;C&quot; uses its top color to show the primary channel ( Red and Green Nun buoy). Use the top color and shape as if it were a stand alone marker if you want to follow the primary channel. In this case leave the Red Nun to the right. Otherwise use the bottom color.
    26. 30. Other Buoyage Systems <ul><li>IALA-B </li></ul><ul><li>Intra-coastal waterways (ICW) </li></ul><ul><li>Uniform State Waterways </li></ul>
    27. 31. Intracoastal Waterways (ICW) <ul><li>Series of tributaries running parallel along the Atlantic and Gulf of Mexico coasts from New Jersey to Texas </li></ul><ul><li>Navigation aids along the ICW are the same as any other U.S. Waterway with the exception of yellow markings </li></ul><ul><li>The yellow markings override the shape or color of the lateral markers they are affixed on </li></ul><ul><li>Red, right, returning also applies to the ICW markers </li></ul><ul><li>Generally South is considered returning </li></ul>
    28. 32. Intracoastal Waterways (ICW) Yellow Squares indicate you should keep this marker on your port side. Yellow Triangles indicate you should keep this marker on your starboard side.
