On 5 March 1993, the Tug Thomas Herbert towing a barge carrying 8,500 tons of coal, sank in 140 feet of water 35 miles off Barnegat Light, N.J.  Five lives were lost at 3am on Sunday 7 March 1993.The sunken vessel was found intact, still attached by a steel cable to the floating barge that she had been towing. The cable showed traces of metal from the hull of another vessel, suggesting that a submarine snagged the tow cable, pulling the tug under. This theory was never proven after recovery and investigation by several groups. The tug was intact until several storms busted open the hull.
