HIGHSPEED 3 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 5,992 gross tonnage it is smaller than 89% of the other 470 ro-pax ships with a recorded tonnage. It is one of 48 ro-pax ships here under the Greece flag, 9.7% of the 493 on the register. The same builder is recorded for 15 other vessels here, all of them ro-pax ships. Its MRV returns name it THUNDER for 2021–2023 and HIGHSPEED 3 for 2024–2025. The reported port of registry changed: GREECE (2021–2024), then PIRAEUS (2025).
Its 11,756 t of CO₂ for 2025 is 61% 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 458.3 kg CO₂, close to the type median of 467.6 kg. It logged 914 hours at sea against a median of 4,243 hours for its type that year. 0.6% 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 2023 (15,113 t) and the lowest 2021 (9,577 t). Of the 5 sister ships listed below with a 2025 return, 1 reported a lower CO₂ per nautical mile than this vessel.

Reported CO₂ by year
Reported CO₂ in 2025 was 22.8% higher than in 2021, for EU/EEA voyages only.
From 2024 to 2025, emissions fell 7.3% and CO₂ per nautical mile rose 5.3%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
