Dexter frequently uses his boat to dispose of his victims (which could implicate him in The Bay Harbor Butcher murders), and in Season 2, he eventually gets caught doing so, first by wiping his boat clean in front of recently installed security cameras, which he has to hastily remove the files from (Dex, Lies and Videotape) and a second, much worse time when Sergeant James Doakes attaches a GPS Tracking Device onto his boat and follows him to a kill site, where he confronts Dexter and discovers his secret (Resistance is Futile).
