Emergency! S06 E19 The Boat

"Squad 51, this is Rampart. Continue to monitor patient and transport immediately."

Richard Bakalyan returns as Charlie, Squad 51's trouble-prone mechanic. The paramedics decide to purchase a boat from Charlie, intendig to sail it on their days off and rent it to others when they're on duty. Of course, things don't quite go as planned, thanks to a wide variety of emergency calls, including the rescue of two boaters from a particularly treacherous stretch of water off Catalina Island, a bookie suffering from a coronary in a locked office, and an explosion in the hospital lab.
