Argonaut, The - Cabin cruiser owned by ex-navy frogman Mike Nelson (Lloyd Bridges) on the maritime adventure SEA HUNT/SYN/1958-62 Aboard the Argonaut, Mike searched the oceans diving for sunken treasure, stolen property and salvage. On the revival series SEA HUNT/SYN/1987-88 starring Ron Ely as Mike Nelson, the boat was called The Sea Hunt. TRIVIA NOTE: The boat's name was derived from the ancient Greek tale of Jason and his ship, the "Argo" built by Argo, a master ship builder. The Argonauts were the ship's crew members who traveled with Jason in search of the Golden Fleece.
