The Orion II, earlier called Clelia II, is a luxury expedition cruise ship. It was originally launched as the Renaissance Four in 1990 by Renaissance Cruises, an operator of cruise ships in Europe. The ship was renamed Clelia II following a refurbishment in 2009.

Travel Dynamics International (TDI), a leading US expedition cruise company, operated the vessel until April 2011. In November 2009, the Australian expedition cruise company Orion Expedition Cruises announced the acquisition of the ship in order to increase its fleet size. The ship was delivered to Orion in April 2011. The ship was renamed the Orion II in June 2011.

Orion II is a sister ship of Island Sky


The Renaissance Four was built in the Cantiere Navale Ferrari-Signani shipyard in La Spezia, Italy. In 2009, the ship was re-launched as Clelia II after a $19.2m refurbishment.

Almaco was awarded a contract to upgrade the ship in February 2011. The refurbishment works were carried out in California. The upgrade included soft-furnishings in all 50 passenger suites and bathrooms, the lobby, main lounge, dining room, library, and public bathrooms. The ship was re-launched after the refurbishment works as Orion II, which made its maiden voyage in June 2011.


The ship has a gross weight of 4,077t, is 290ft long, 50ft wide and has a draft of 12ft. The ship has a crew of 65.

The vessel meets all international and US Coast Guard safety regulations and is equipped with the latest navigational and communications technologies, retractable fin stabilizers, an ice-strengthened hull and a fleet of Zodiacs.
