The Coast Guard and partner agencies monitor debris and pollution Monday after two boats grounded on the Manasquan Inlet jetty Sunday, stranding four people. The captain of the 32-foot boat, Slashbacks, contacted Coast Guard Sector Delaware Bay watchstanders at 11:30 p.m. Sunday via VHF-FM channel 16 radio reporting the Slashbacks lost power while towing a 31-foot boat, Lady Jane, through Manasquan Inlet. As a result of the power loss, the tow line parted and both boats grounded on Manasquan Inlet’s southern jetty, stranding three people on the jetty and one person aboard the Slashbacks.
