SS Dolphin IV (formerly Zion of Zim Lines), was built in Germany as war reparations for Israel in 1956.

The owners of Ulysses Cruises/Florida Nautica made the decision in 1984 to handle the sales and marketing for the ship.

The ship remained in operation for Cape Canaveral Cruise Line until September 2000 when it was forced out of service because it needed 3.5 million dollars in required maintenance.

As a result, the ship was forced to lay up at Freeport, Bahamas for three years awaiting repairs.

Due to the state of disrepair of fresh water and sewage holding facilities, the ship was sold for scrap in 2003.
