MANANNAN against its type
Built in 1998, it is 2 years older than the median ro-pax ship on this register, which was built in 2000 (483 vessels with a known build year). At 5,743 gross tonnage it is smaller than 90% of the other 470 ro-pax ships with a recorded tonnage. It is one of 2 ro-pax ships here under the Isle of Man flag, 0.4% of the 493 on the register. The same builder is recorded for 21 other vessels here, all of them ro-pax ships. The returns for 2018–2025 all give Douglas as port of registry.
Its 957 t of CO₂ for 2025 is 97% below the median of 30,062 t among the 417 ro-pax ships on this register that reported for 2025. Per nautical mile it emitted 420.5 kg CO₂, 10% below the type median of 467.6 kg. It logged 86 hours at sea against a median of 4,243 hours for its type that year. 0.0% of its 2025 emissions were at berth; the median for ro-pax ships was 6.7%. Across 7 years with reported emissions, the highest was 2018 (25,283 t) and the lowest 2021 (688 t). Of the 6 sister ships listed below with a 2025 return, 2 reported a lower CO₂ per nautical mile than this vessel.

Reported CO₂ by year
Reported CO₂ in 2025 was 96.2% lower than in 2018, for EU/EEA voyages only. No return is recorded for 2023, so the series has gaps.
From 2024 to 2025, emissions fell 19.0% and CO₂ per nautical mile fell 5.2%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
