them as "The depth at (such a) wharf was (so many) feet in (July 1940)." Also give length of avail- 

 able berths, storage, and transportation facilities, cargo-handling gear, fueling facilities, information 

 about supplies, power connection, water, etc. 



The Pilot must be written primarily for the convenience of the majority of its users. If the 

 region is an isolated one frequented only by small craft, such as those used by fishermen and yachtsmen, 

 more detailed descriptions of wharves, floats, and facilities for such craft must be included than would 

 be required for a well-developed section where the existence of these facilities may sometimes be 

 assumed. 



Regardless of source, the date of the information must be considered, and if the information is 

 of a changeable type, it must be of recent date or be checked. 



If a wharf is reported to be dilapidated or in ruins, consider the advisability of giving the date if 

 there appears to be a chance of repairs being made. It is important to note old piling that may be a 

 menace to navigation. 



WINDS.^ — Express in nautical miles per hour, and points true, or give force by Beaufort scale. 



WRECKS. — Information regarding the occurrence of wrecks is often of value. Inquiries must 

 be made, and the cases investigated to determine the various causes contributing in any way to marine 

 disasters, such as little-known currents, inadequacy of aids to navigation, misleading or deceptive 

 bottom relief in approaches, shifting shoals and channels, imperfect or inadequate charts. In general, 

 the subject of wrecks can be treated in Chapter 2 of the Pilot to very good advantage, although mention 

 should be made at the proper places in the text where there appear to be an unusual number of wrecks, 

 indicating that there are unusual dangers. If there is a natural reason for wrecks in any locality, 

 explain it, and state how to avoid those conditions. 



Wrecks that are of importance to the navigator, either as dangers or landmarks, should be de- 

 scribed in as much detail as warranted. Do not describe those that will be removed before the Pilot 

 is published. 



917. Nomenclature and Terminology 



Abbreviations. — Abbreviations must agree with those in use on the charts (see 

 Symbols and Abbreviations chart, fig. 189). For further reference, use the Govern- 

 ment Style Manual. In case of imcertainty, comply with the rules given in the latest 

 edition of the "American Standard Abbreviations for Scientific and Engineering Terms," 

 Pamphlet No. ^S'^.ZlO.1-1941 (Library No. 503 A 51). 



Capitalization, compounding, and punctuation. — In general, the rules given in the 

 Style Manual may be accepted as final authority, but in some cases, Webster's New 

 International Dictionary, and other authorities must be considered. 



Definitions. — "A Glossary of Sea Terms," by G. Bradford, is a reliable reference 

 work. 



Terminology. — The following terminology is in use in the Coast Pilot Section in 

 1942. Capitals and lower-case letters are used as in the examples. Obviously such 

 a list cannot be complete, but the correct usage with respect to terms not included 

 can be determined by analogy.
