General Comments

S0002-02 --S-B600-RU --; SWMB AND SSS DATA INDICATE THAT THIS ITEM IS A SHIPWRECK SURVEYED IN POSITION: 41-09-19.30 N 072-25-00.632 W. THIS ITEM IS APPROXIMATELY 22 METERS LONG BY 7 METERS ABEAM WITH A LEAST DEPTH OF 120 FEET. HYDROGRAPHER BELIEVES THIS WRECK TO BE THE THAMES DUE TO THE DIMINSIONS AND LOCATION OF THE WRECK AND RECOMMENDS REMOVING THE "118 Wk Rep (1983)" FROM THE CHART AND CHARTING "121 Wk" IN THE SURVEYED POSITION. [ENETERED 8/5/2004 JCM] This item was completed by the RUDE while performing homeland security survey S-B600. Whether they proved or disproved the item is unclear.(Proved item---Validated by RES 8/03/07) OPR-B370-TJ-04-- Chart AWOIS Item #2729 non-dangerous sunken wreck, least depth known 122 feet, and text "Wk" at the present survey position in Latitude 41°09'19.290"N, Longitude 072°25'00.591"W.This feature is the least depth over a wreck that was located with 100% MBES (EM 1002) and developed with 100% SSS (KLEIN 5500). The wreck is approximately 23 meters long and 5 meters wide. The feature is located 1.1 meters from the position of AWOIS 2729 and approximately 10 meters outside the 1850-meter search radius of AWOIS 1813. Although the current feature does not lie within the 1850-meter search radius of another AWOIS item, #1814, the history for AWOIS 2729 indicates that a past hydrographer believed that AWOIS 2729 may have been the wreck of AWOIS 1814 (the tug "Thames"), whose 1850-meter search radius (1) is centered 4240 meters to the northwest and (2) does not contain any wrecks. The current hydrographer is unable to definitively substantiate the past claim that the wreck of AWOIS 2729 is the wreck of AWOIS 1814 because (1) no diver investigation was done and (2) the current feature does not precisely match the description of the tug "Thames" provided in AWOIS 1814's proprietary section; however, the current feature does closely match the length and width dimensions of AWOIS 1813 (believed to the tug "Barataria"), although the hydrographer can not definately say wether or not the current feature is indeed the wreck of AWOIS 1813 because no diver investigation was performed and another wreck also closely matches the description of AWOIS 1813 (RES 11/30/07).
