916 HYDROGRAPHIC MANUAL PaGE 834 



The Intracoastal Waterway Pilot should describe the inside passage, and briefly the channels 

 and inlets extending from it to the sea, but should not give coastal descriptions, or more than refer 

 to ports not located on the route or reached by it. (See 914.) 



JETTIES. — State if jetties cover and are dangerous, and at what approximate stage of the tide. 

 Describe, as warranted by their value for protection, for landmarks, and as dangers, if so. Give 

 height above mean high water. 



KELP. — Where important, the extent of kelp beds should be given. If it grows on shoals, it 

 should be described. Include appearance, quantity, whether seasonal or not, whether it tows under 

 at times, and how it shows. (See 3623& and 7864.) 



LANDFALLS. — -First landfalls are described in Chapter 2 of the Pilot. Local descriptions are 

 given in place in the text. Describe the appearance of the coast on making the land — on a bold coast 

 the headlands, peaks, etc., with their form, color, and height; and on a flat coast, the water tanks, 

 spires, beacons, etc. Streaks of color in bluffs, etc., may be useful identifying features. Mention 

 any local features that may be used in fog or at night if the aids to navigation are not functioning. 



LANDING FIELDS. — Report any in the locality visited. Any of importance to navigation 

 should be described in the Pilot; for example, seaplane landings at which supplies are available, or 

 that affect navigation. Mention regular routes and special services available in isolated places. 



LANDING PLACES. — These are of special importance on dangerous coasts. State location and 

 peculiarities affecting landings, stage of tide best for landing, and when dangerous, etc. 



LANDINGS. — State whether public or private. If the former, give the depth of water alongside 

 and in the approach. State whether fuel, water, and supplies are available and how they are taken 

 on board. (See Floats.) 



LANDMARKS. — Instructions for obtaining and furnishing information on landmarks by regular 

 survey parties are given in 155 and 8534. 



Describe all prominent landmarks likely to be of most use for navigation or for future survey oper- 

 ations. If objects, such as mountains, hills, cliffs, islets, or rocks, are recommended as landmarks, 

 give their measured or estimated heights. State if mountains mentioned are often cloud-capped. 



Check in the field landmarks shown on charts or mentioned in Pilots, and report those that are 

 no longer of value. Landmarks may be located by sextant angles. If new landmarks suitable for 

 charting exist, select and locate them. Those sighted and recommended for charting, but not located, 

 should be reported to the Office for future location. All landmark information shall be reported on 

 Form 567 in accordance with 8534. 



LANGUAGE. — Simplicity, clarity, and conciseness are essential. No ambiguous or indefinite 

 expressions should be used. The text should be clear even to a landsman going to sea for the first 

 time. 



LATITUDES, LONGITUDES, AND CHART NUMBERS.— About once each two pages in the 

 text, one feature shall be selected and marked with an asterisk. The footnote shall consist of the lati- 

 tude and longitude of the feature to the nearest tenth of a minute and the numbers of all the Coast and 

 Geodetic Survey charts which include that position. Latitudes and longitudes of lights and other 

 features are not to be given in the text, the need being fulfilled by the footnotes. 



LIFEBOAT STATIONS.— Include in a table in the appendix all Coast Guard Lifeboat Stations 

 in the region and their locations, and mention each with location in the text. Indicate those that are 

 inactive. 



LIGHTHOUSES.— (See Lights.) 



LIGHTS. — Fixed lighted aids to navigation shall be called "Lights" in the Pilots, and the name 

 given in the Light List shall be used and bold-faced in the text. With the description of the fight, 

 consisting of its elevation and the distance it is visible, shall be given a description of the structure 

 supporting it, including, if necessary, adjacent structures. This description shall include all details of 

 the appearance of the structure that might aid in identifying it in daytime, using the same nomen- 

 clature used in the Light List. Omit color of light, characteristics, phase, period, and sectors, except 

 in unusual cases. Give types of fog signals operated, but not the characteristics. The term "light- 

 house" is not to be used as a part of the name of the aid to navigation, but it may be used in the 

 description of the structure, or a house or tower no longer used to show a light may be referred to as an 

 "abandoned lighthouse tower" or an "abandoned lighthouse." Use the term which is most descriptive. 



LIGHTSHIPS. — Give the appearance by day, identifying marks, number of masts, etc. Give 

 the number of lights, elevation, and distance visible. Omit changeable characteristics, as in case of 

 other fights. State type of fog signal operated, but not the characteristics. If auxiliary lights and 

 fog signals are used in emergencies, describe them in the same manner. Describe any lights, etc., used 

 to show the heading of the lightship.
