General Comments

HISTORY LNM37/73--09/17/1973, 5TH CGD; A 17 FOOT OUTBOARD BOAT HAS BEEN REPORTED SUNK APPROXIMATELY 100 YARDS WEST OF CHESAPEAKE LIGHT. H09959/81--OPR-D103-MI/PE; DEPTHS ON THE PRESENT SURVEY IN THIS AREA ARE 38 TO 40 FEET. ITEM REQUIRED A LIMITED INVESTIGATION WHICH WAS ACCOMPLISHED USING 90 METER LINE SPACING OVER AN AREA WITH A 1000 METER RADIUS OF THE REPORTED POSITION. THE REDUCED LINE SPACING FAILED TO LOCATE THE WRECK ON THE FATHOGRAMS. SEVERAL SPORT DIVE BOATS WERE SEEN ANCHORED OFF CHESAPEAKE LIGHT DURING THE SURVEY. PEIRCE MADE RADIO CONTACT WITH THEM, INQUIRING AS TO THE EXISTENCE OF ANY WRECK NEAR THE LIGHT. ALL REPLIES FROM THE DIVE BOATS WERE NEGATIVE. IT IS THEREFORE RECOMMENDED THAT THE ITEM BE CHARTED IN LAT. 36-54-16N, LONG. 75-42-52W (NAD 27) AS A NON-DANGEROUS WRECK WITH "EXISTENCE DOUBTFUL". CURRENTLY CHARTED AS SUBMERGED DANGEROUS WRECK PD. (ENT 03/02, PSH) H11303 (2006) Survey Position: 36° 54' 17.455" N, 075° 42' 48.382" W Least Depth: 12.07 m Timestamp: 2006-101.20:10:09.717 (04/11/2006) Survey Line: h11303 / tj_3102_reson8101 / 2006-101 / 017_2008 Profile/Beam: 870/34 Charts Affected: 12208_1, 12207_1, 12221_1, 12280_2, 12200_1, 13003_1 Remarks: Object within search radius of AWOIS 11436 rising approximately 53cm off bottom, found by 8101 and Klein 5000. Corrected to MLLW, verified tides final zoning. Hydrographer Recommendations: Due to its extremely small size (17') minimal height (appx 53cm) and proximity to a much larger object(Chesapeake Light), the hydrographer recommends the obstn be removed from the chart and AWOIS 11436 be removed from the database. Office Notes: Concur with clarification. There are other, shoaler, outer-beam hits on the feature, but the current sounding was chosen as the least depth because it is near nadir. Chart present survey soundings.
