SEABOURN OVATION against its type

Built in 2018, it is 8 years newer than the median cruise ship on this register, which was built in 2010 (195 vessels with a known build year). At 41,865 gross tonnage it is smaller than 75% of the other 177 cruise ships with a recorded tonnage. It is one of 67 cruise ships here under the Bahamas flag, 33.2% of the 202 on the register. The same builder is recorded for 132 other vessels here, 60 of them cruise ships. Holland America Line is linked to 17 vessels on this register. The returns for 2018–2025 all give Nassau as port of registry.

Its 25,034 t of CO₂ for 2025 is 20% below the median of 31,269 t among the 200 cruise ships on this register that reported for 2025. Per nautical mile it emitted 588.4 kg CO₂, 28% below the type median of 821.3 kg. It logged 3,988 hours at sea against a median of 3,133 hours for its type that year. 18.7% of its 2025 emissions were at berth; the median for cruise ships was 15.1%. Across 6 years with reported emissions, the highest was 2019 (33,283 t) and the lowest 2018 (18,860 t). Of the 8 sister ships listed below with a 2025 return, 1 reported a lower CO₂ per nautical mile than this vessel.

Reported CO₂ by year

Reported CO₂ in 2025 was 32.7% higher than in 2018, for EU/EEA voyages only. No return is recorded for 2020, 2021, so the series has gaps.

From 2024 to 2025, emissions fell 6.0% and CO₂ per nautical mile rose 0.1%.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 6 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.
