NATIONAL GEOGRAPHIC EXPLORER against its type

Built in 1982, it is 28 years older than the median cruise ship on this register, which was built in 2010 (195 vessels with a known build year). At 6,471 gross tonnage it is smaller than 97% 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 1 other vessel here. The returns for 2019–2025 all give Nassau as port of registry.

Its 4,191 t of CO₂ for 2025 is 87% below the median of 31,269 t among the 200 cruise ships on this register that reported for 2025. Per nautical mile it emitted 194.6 kg CO₂, 76% below the type median of 821.3 kg. It logged 2,153 hours at sea against a median of 3,133 hours for its type that year. 12.4% of its 2025 emissions were at berth; the median for cruise ships was 15.1%. Across 3 years with reported emissions, the highest was 2019 (4,572 t) and the lowest 2024 (3,772 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

2019: 4,572 t20194,5722024: 3,772 t20242025: 4,191 t20254,191

Reported CO₂ in 2025 was 8.3% lower than in 2019, for EU/EEA voyages only. No return is recorded for 2020, 2021, 2022, 2023, so the series has gaps.

From 2024 to 2025, emissions rose 11.1% and CO₂ per nautical mile fell 5.9%.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 3 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.
