BASTØ II against its type

Built in 1997, it is 3 years older than the median ro-pax ship on this register, which was built in 2000 (483 vessels with a known build year). At 5,505 gross tonnage it is smaller than 93% of the other 470 ro-pax ships with a recorded tonnage. It is one of 37 ro-pax ships here under the Norway flag, 7.5% of the 493 on the register. The same builder is recorded for 20 other vessels here, 11 of them ro-pax ships. Bastø Fosen is linked to 7 vessels on this register. The returns for 2021–2025 all give Horten as port of registry.

Its 1,758 t of CO₂ for 2025 is 94% 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 114.7 kg CO₂, 75% below the type median of 467.6 kg. It logged 1,471 hours at sea against a median of 4,243 hours for its type that year. 12.0% of its 2025 emissions were at berth; the median for ro-pax ships was 6.7%. Across 5 years with reported emissions, the highest was 2021 (2,989 t) and the lowest 2025 (1,758 t). Of the 5 sister ships listed below with a 2025 return, 0 reported a lower CO₂ per nautical mile than this vessel.
