SEVEN SEAS NAVIGATOR against its type
Built in 1999, it is 11 years older than the median cruise ship on this register, which was built in 2010 (195 vessels with a known build year). At 28,550 gross tonnage it is smaller than 86% 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. No other vessel on this register is recorded with the same builder. Regent Seven Seas Cruises is linked to 6 vessels on this register. The returns for 2018–2025 all give Nassau as port of registry.
Its 23,714 t of CO₂ for 2025 is 24% below the median of 31,269 t among the 200 cruise ships on this register that reported for 2025. Per nautical mile it emitted 571.6 kg CO₂, 30% below the type median of 821.3 kg. It logged 3,101 hours at sea against a median of 3,133 hours for its type that year. 15.1% of its 2025 emissions were at berth; the median for cruise ships was 15.1%. Across 6 years with reported emissions, the highest was 2025 (23,714 t) and the lowest 2022 (11,138 t). Of the 8 comparable vessels listed below with a 2025 return, 7 reported a lower CO₂ per nautical mile than this vessel.

Reported CO₂ by year
Reported CO₂ in 2025 was 71.3% 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 rose 13.8% and CO₂ per nautical mile rose 2.5%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
