The Coast Guard Monday night was searching for a capsized johnboat spotted off Dania Beach.
A good Samaritan called the Broward Sheriff's Office about a capsized 15-foot vessel not far from the pier, and BSO in turn alerted the Coast Guard.
The Broward County Sheriff's Office and Fort Lauderdale Fire Rescue are helping with the search.
Officials say after a little persuasion, the sea lion hopped aboard the boat and posed for photos. The watch standers issued an urgent marine information broadcast, launched a Station Fort Lauderdale 45-foot Response Boat Medium crew and diverted the crew of the Coast Guard Cutter Dolphin.
