    • Each volume of the Light List details the aids to navigation in geographic order from north to south along the Atlantic coast, from east to west along the Gulf coast, and from south to north along the Pacific coast. It lists seacoast aids first, followed by entrance and harbor aids listed from seaward.

    Intracoastal Waterway aids are listed last in geographic order in the direction from New Jersey to Florida to the border of Texas and Mexico. The Light List is not intended to be used in place of nautical charts or Coast Pilots, but as an adjunct to good navigation practices.

    Not included are Coast Guard mooring buoys and some buoys having no lateral significance; such as special purpose, anchorage, fish net, and dredging. I - St. V - Mississippi River System. VII - Great Lakes. The list is published in seven volumes, as Publication numbers through and are usually referred to as the List of Lights, and should not be confused with the U. Coast Guard's Light List.

    Each volume Corresponds to a defined geographic region as shown on the index chartlet on the inside front covers. Major fixed and outermost floating aids to navigation, such as sea buoys, safety fairway buoys, traffic separation buoys, etc. It is simple and not subject to breakdown. Lead line limitations include: Lead lines should be wetted and stretched prior to marking. Handheld Leadline Figure When sufficient momentum is obtained and at shoulder level, throw the lead as far forward as possible.

    Pull the slack out of the line until you feel the lead on the bottom. There are two ways to report soundings, depending upon where the watermark is located on the lead line. Depth that corresponds to any mark on the lead line is reported: Intermediate whole fathoms are called deeps. Report fractions of a fathom as halves and quarters, such as, and a half seven or less a quarter ten.

    A radio direction finder RDF will allow you to take bearings on radio transmitters which are well beyond your visual range. One type of RDF requires manual operation to obtain bearings.

    The automatic radio direction finder ADF automatically takes and displays the bearings. Radio bearings are not as accurate as visual bearings. It takes a great deal of experience to be able to effectively use the equipment. Be very careful when plotting radio bearings, especially in the correct direction. The VHF-FM homer measures the small difference in angle of a signal, from a known source and received by each antenna, then converts this signal into the angle of direction from your boat.

    This direction is shown on a swinging needle display screen mounted in the pilothouse.

    The source must continue to transmit for you to track it. The procedure for using the homer is outlined below: A needle centered in the middle of the screen may indicate a source dead ahead - or dead astern. The homer cannot distinguish this since both signals would arrive at 90 degrees to each antenna. To determine which direction - turn off course 30 degrees and observe the needle. If it directs you to return to your original heading, the source is ahead.

    If the needle points elsewhere - follow it.

    The indicator needle is affected by radio wave reflections and may bounce around when passing near large metal objects. The homer has six channels 6, 12, 13, 14, 16, and 22 in addition to the weather channels.

    Set the channel switch to the channel receiving the signal. Turn the boat in the direction of the pointer until it centers itself.

    Change course as indicated by the needle and proceed to the source of the signals, giving due caution to navigation hazards that may be between you and your destination. Light Lists provide more complete information concerning aids to navigation than can be shown on charts. They are not intended to replace charts for navigation and are published in seven volumes.

    Tide tables give daily predictions of the height of water - at almost any place - at any given time - and are published annually in four volumes. Instructions are provided within the publication on how to use the tables. These tables provide the times of maximum flood and ebb currents, and times of the two slack waters when current direction reverses.

    They also tell the predicted strength of the current in knots. The time of slack water does not correspond to times of high and low tide.
