SPIRIT OF DISCOVERY against its type

Built in 2019, it is 9 years newer than the median cruise ship on this register, which was built in 2010 (195 vessels with a known build year). At 58,119 gross tonnage it is smaller than 64% of the other 177 cruise ships with a recorded tonnage. It is one of 2 cruise ships here under the United Kingdom flag, 1.0% of the 202 on the register. The same builder is recorded for 65 other vessels here, 29 of them cruise ships. Saga Cruises is linked to 2 vessels on this register. The returns for 2021–2025 all give London as port of registry.

Its 37,748 t of CO₂ for 2025 is 21% above the median of 31,269 t among the 200 cruise ships on this register that reported for 2025. Per nautical mile it emitted 575.5 kg CO₂, 30% below the type median of 821.3 kg. It logged 4,603 hours at sea against a median of 3,133 hours for its type that year. 9.6% of its 2025 emissions were at berth; the median for cruise ships was 15.1%. Across 5 years with reported emissions, the highest was 2024 (45,183 t) and the lowest 2021 (17,378 t). Of the 7 sister ships listed below with a 2025 return, 1 reported a lower CO₂ per nautical mile than this vessel.

Reported CO₂ in 2025 was 117.2% higher than in 2021, for EU/EEA voyages only.

From 2024 to 2025, emissions fell 16.5% and CO₂ per nautical mile rose 3.6%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.

Sources and how to read this

This page draws on 5 MRV reporting years, 5 of 5 vessel particulars, AIS movements in Norwegian waters and a licensed photograph. Not found in the sources for this vessel: an efficiency ranking, a name history, a sanctions listing and US port state inspections.

Empty means unreported, never zero. How EEOI, distance, percentiles and sister ships are handled is explained under reading a vessel page. Something wrong? See corrections.
