SEABOURN SOJOURN against its type

Built in 2010, it is the same age as the median cruise ship on this register (build year 2010, 195 vessels with a known build year). At 32,477 gross tonnage it is smaller than 80% 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 5 other vessels here, 3 of them cruise ships. Holland America Line is linked to 17 vessels on this register. The returns for 2019–2025 all give Nassau as port of registry.

Its 14,132 t of CO₂ for 2025 is 55% below the median of 31,269 t among the 200 cruise ships on this register that reported for 2025. Per nautical mile it emitted 504.4 kg CO₂, 39% below the type median of 821.3 kg. It logged 2,300 hours at sea against a median of 3,133 hours for its type that year. 15.9% of its 2025 emissions were at berth; the median for cruise ships was 15.1%. Across 5 years with reported emissions, the highest was 2023 (18,039 t) and the lowest 2019 (1,601 t). Of the 8 comparable vessels listed below with a 2025 return, 4 reported a lower CO₂ per nautical mile than this vessel.

Reported CO₂ by year

Reported CO₂ in 2025 was 782.9% higher than in 2019, for EU/EEA voyages only. No return is recorded for 2020, 2021, so the series has gaps.

From 2024 to 2025, emissions fell 0.2% and CO₂ per nautical mile rose 1.0%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
