ULTRA CAPE TOWN against its type
Built in 2013, it is 6 years newer than the median general cargo ship on this register, which was built in 2007 (2,852 vessels with a known build year). At 13,110 gross tonnage it is larger than 70% of the other 2,665 general cargo ships with a recorded tonnage. It is one of 181 general cargo ships here under the Marshall Islands flag, 5.9% of the 3,081 on the register. The same builder is recorded for 14 other vessels here, 10 of them general cargo ships. Its MRV returns name it ULTRA CAPE TOWN for 2018–2021 and WM CRYSTAL for 2022–2025. The reported port of registry changed: HONG KONG (2018–2021), then SINGAPORE (2022), then MAJURO (2023–2025).
Its 1,476 t of CO₂ for 2025 is 48% below the median of 2,820 t among the 2,469 general cargo ships on this register that reported for 2025. Per nautical mile it emitted 146.5 kg CO₂, 20% above the type median of 122.2 kg. It logged 1,008 hours at sea against a median of 3,044 hours for its type that year. 3.5% of its 2025 emissions were at berth; the median for general cargo ships was 4.3%. Across 7 years with reported emissions, the highest was 2019 (6,964 t) and the lowest 2023 (872 t). Its efficiency percentile within the type went from 99 in 2019 to 71 in 2023 (lower is more efficient). Of the 3 sister ships listed below with a 2025 return, 1 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2023
Position 236 of 331 qualifying general cargo ships by EEOI, at the 71st percentile. The dashed line is the type median, 21.1; this vessel reported 28.5.
EEOI divides emissions by transport work, which for this vessel and year was 30,557,659 tonne-miles over 4,905 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 14.8% lower than in 2018, for EU/EEA voyages only. No return is recorded for 2024, so the series has gaps.
From 2023 to 2025, emissions rose 69.3% and CO₂ per nautical mile fell 17.6%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
