MV Sea Spirit Review

Review of MV Sea Spirit

The 1991-built Sea Spirit cruise ship was constructed by Nuovi Cantieri Apuania SpA (in Marina di Carrara Italy) and launched under the name "Renaissance V" for shipowner Renaissance Cruises (1989-founded/2001-defunct). Subsequently, the boat was operated as "Spirit of Oceanus" by Cruise West (1973-founded/2010-defunct) before being modified/drydock refitted (the hull was ice-strengthened) in 2010 to become more suitable for polar cruises. Since October 2010 are operated exclusively polar itineraries - to Arctic and Antarctic destinations.

The vessel (IMO number 8802868) is currently Portugal-flagged (MMSI 255806397) and registered in Madeira/Funchal. Before 2019, it was Bahamas-flagged (MMSI 309224000/Nassau-registry).

From the same shipbuilder/sisterships are Caledonian Sky (Renaissance VI), Hebridean Sky (Renaissance VII), Island Sky (Renaissance VIII).

NEWS: In May 2019, the shipowner (SunStone Ships Inc) put the vessel for sale. It is currently chartered to Poseidon Expeditions (through May 2022), which means it can be either bareboat-chartered or acquired, with delivery in May 2022.

The itinerary program featured the company's first-ever "Voyage to The Arctic" (itinerary June 17-29) to Iceland's northern fjords and also along the Arctic Circle to Norway, from where the ship continued to Bear Island and Spitsbergen Archipelago.

In 2017, Poseidon Expeditions signed with the shipowner SunStone Ships a 4-year charter deal (until 2021) for Sea Spirit. The ship started charter operations for Poseidon Expeditions in May 2018. Among the planned itinerary destinations are Antarctica, Western Greenland, Svalbard Islands (Norway), British Isles (UK).

MS Sea Spirit was drydock refurbished in 2017 in Vigo Spain. By this USD 2,5+million project, all staterooms were renovated. Previously (during drydock 2015), all public areas were redesigned and renovated. During drydock 2019 (April) to the vessel were installed two Rolls Royce Zero Speed Stabilizers. These are in-hill mounted (retractable) fin stabilizers that eliminate vibrations and noises. They also reduce the vessel’s rolling (when anchored, moored or adrift) and dynamic drag (when both units are deployed during cruising).

The April-May 2019 drydock (at Naval Rocha Shipyard, Lisbon Portugal) resulted in complete interior upgrade plus advanced maritime technology upgrades, including 2 retractable fin stabilizers. These new units (Rolls Royce Zero Speed Stabilizers) provide high roll damping performance at sea, as well as while the boat is drifting or anchored. They are also designed to eliminate vibrations and noise. Both stabilizers are fully compatible with environmentally acceptable lubricants and feature 4 main seals for additional redundancy. The system is computer-based, with a programmable logic controller developing different patterns depending on weather and sea conditions. The drydock improvements will also result in re-certifying the ship for the new vessel requirements by the updated IMO Polar Code allowing passenger shipping operations in polar waters.

In May 2019, SunStone Ships Inc (US shipowner) put Sea Spirit for sale. The vessel is currently chartered to Poseidon Expeditions through May 2022, meaning it can be bareboat-chartered or purchased with delivery in May 2022.

In late-June 2019, the ship charterer Poseidon Expeditions announced the 23-day solar eclipse-themed voyage to Antarctica (Nov 20 through Dec 12, 2021) roundtrip from Ushuaia Argentina. The solar eclipse will occur on December 4 (itinerary's Day 14). Early booking prices started from USD 16,560 (per person rates based on triple occupancy) and USD 21,870 (pp double-occupancy rates).

In early-April 2020, Poseidon Expeditions extended the Sea Spirit cruise ship charter deal through May 2024.
