System• 2.1 Identify the two IALA regions for the United States and state

the region applicable to the trainee. IALA Region AU.S. lateral aids to navigation at certain Pacific Islands (West of the

international date line) are located within IALA Region A and thus exhibit opposite color significance. Port hand marks are red with square or cylindrical shapes while starboard hand marks are green with triangular or conical shapes.

IALA Region BVirtually all U.S. lateral marks are located in IALA Region B and

follow the traditional 3R rule of Red, Right, Returning.

to head of navigation. Local terminology describes aids as Right or Left descending bank (RDB or LDB)

used

• 3.6 Correcting the depth of water for the height of tide or river/lake level. a. Explain the concept of “Height of Tide at any time.” (Google)

There may be five situations when you need to know the exact depth of the water; 99 percent of the time, the depth printed on the chart is sufficient for the average boater. The question asked most often by boater is “When is high tide?” Unfortunately, most new boaters don’t realize that the depths marked on their chart refer to the Mean Lower Low Water (MLLW) mark and that their greatest concern should be for the time of lowest water. Here is a list of the five situations.


• 3.6 Correcting the depth of water for the height of tide or river/lake level.• a. Explain the concept of “Height of Tide at any time.”

Knowing the Height of tides for a specific point and time. Examples:

1. Know the time of high or low water.2. Know the height of the tide at a specific point in time.3. Know the depth of the water at various points of time over an extended period4. To determine the height (distance) from the waterline to the span of a bridge for a specific point in time.5. Know the time when you have a certain clearance of depth

over an obstruction such as a shoal of bar.

3.6 Correcting the depth of water for the height of tide or river/lake level - b. Explain how to determine the tides or depth of water for the trainee's area Example: What is the depth of water at this buoy at 1100 on Jan 17, 2012?

Charted depth of buoy is 14 feet at MLLW 1100 on 17 Jan 2012

3.6 Correcting the depth of water for the height of tide or river/lake level - -b. Explain how to determine the tides or depth of water for the trainee's area. Use the nearest tide table reference station or GPS tide table for your area Using the GPS Tide Table reference station

area.

3.6 Correcting the depth of water for the height of tide or river/lake level.c. Explain how to read a charted depth on a chart and how it compares to

the reading from an electronic echo sounder. The charted depth is at the chart datum of MLLWThe echo sounder is showing depth from the transducer to the bottom

d. Explain how the depth reading from an echo sounder is corrected. You must add the distance from the vessel waterline to the bottom of

the transducer.


• 3.7 GPS Set Up (Student should have GPS or Owner’s Manual)

a. Configure GPS for local chart datumNorth American Datum of 1983 (NAD 83) World Geodetic System 1984 (WGS 84)

b. Explain the difference between standard and WAAS-enabled GPS, and why WAAS is preferred when recording a position.Standard GPS Accuracy is better then 20 meters wwWide Area Augmentation System WAAS GPS Accuracy is

better then 2 meters ww - More accurate c. Describe how to configure GPS to read True heading OR how

to correct for variation. Most GPS default reads TRUE heading Use Chart variation to set for MAGNETIC heading
