to the Commander of the nearest Coast Guard District and to the Washington Office 

 in writing. The report should be accompanied by a photostat or tracing of the appU- 

 cable part of the new sui*vey as shown on the boat sheet, with a recommendation as to 

 where the aid should be located. (See also 3832.) 



Wliere the survey discloses the need for additional aids to navigation to mark newly 

 discovered dangers, recommendation shall be made promptly to the Commander of the 

 nearest Coast Guard District, and a copy of the recommendation shall be forwarded to 

 the Washington Office. 



Where the survey discloses the need for additional aids to navigation to mark chan- 

 nels, or for any reason other than that given in the preceding paragraph, the recommen- 

 dation shall be forwarded to the Washington Office accompanied by a photostat or 

 tracing of the applicable part of the boat sheet. 



8532. Positions of Fixed Aids 



The geographic positions of all fixed aids to navigation which were located during 

 the season should be reported on Form 567, Landmarks for Charts. In making out this 

 form, the applicable parts of the instructions given in 8534 should be followed. It is 

 important that the names of the aids entered on the form be identical with those in the 

 Light Lists. 



It is to be emphasized that the positions of all aids located are to be reported, even 

 if the new positions merely serve to verify previous geographic positions, or the charted 

 positions. 



The report shall be made on an area or seasonal basis. A separate report for each 

 hydrographic sheet is not desired. The aids to navigation shall be listed separately 

 from the landmarks, since these reports serve a different purpose in the Office. (See 

 also 3831.) 



Azimuths of ranges determined in accordance with 3833 shall be reported in the 

 Descriptive Report for each survey (see 842P). 



8533. Chart of Objects for Use of United States Coast Guard 



The objects selected for the use of the United States Coast Guard in accordance 

 with 1551, shall be plotted on a copy of the latest print of the largest-scale chart of the 

 area. The chart should not be cut into sections, even though the notes apply to only a 

 part of the area of the chart. A short legend as, "Objects for Use of U. S. Coast 

 Guard," and the date of the field survey from which the information was obtained, 

 shall be shown on this chart. 



The three objects selected for each fix shall be encircled in red on the chart, 

 whether already charted as landmarks or plotted by the survey party. Adjacent to 

 the position of each object selected, a description from which the object may be identi- 

 fied shall be noted in red. The fix selected for each aid shall be indicated on the chart 

 by red arrows at the aid, pointing toward the objects to be used. 



Charts with the legend "N.A. 1927" printed in the upper right-hand corner are on 

 the North American datum of 1927. Charts for continental United States without 

 legend in the upper right-hand corner, may be on either the North American datum of 

 1927 or the North American datum (see 1125 and 2171). The geographic datum of a 

 chart may be ascertained by comparing the scaled position of a charted object with its 

 geographic position as given in the triangulation data (see 7362) ; or the datum will be
