It's now sitting on the beach behind Pam Harrington's home.She said she's been told the vessel's owners are responsible for removing it from the beach.After the boat went down, the two men aboard spent the night in a life raft before being rescued by a U.S. Coast Guard crew out of Fort Myers Beach.
