Fixture data — fictional vessels, no real AIS observations
In the last 24 hours, this vessel alone
7.2–8.6tonnes CO₂
That is as much CO₂ as roughly 7–9 people flying economy from Amsterdam to New York — produced by one yacht in a single day.
No per-guest, per-kilometre rate for this window: the vessel logged no observed distance, so there are no guest-kilometres to divide by.
Estimated — published max capacity — Published maximum guest berths, excluding crew. Not a count of people aboard. Guest figure uses 13 published maximum guest berths. Cruise reference: ICCT (EU MRV-verified reporting). Full detail below and in the methodology.
GT thresholds are regulatory reference points, not an inclusion criterion of this tracker. Length alone (≥60 m LOA) decides which yachts are followed here.
Capacity figures come from published specifications. They describe how many people the vessel can accommodate, not how many are aboard.
Positions are delayed by at least 15 minutes and never presented as realtime.
Litres are the source datapoint; CO₂ is derived from them, not the other way round. Fuel density 0.840 kg/L (fallback, no vessel-specific value published) × EU MRV factor 3.206. Methodology.
Each state uses time actually spent in that state × the best available state-specific fuel rate. Anchor and in-port rates are never derived as a percentage of the underway rate; YETI and Heesen fleet splits are used only as sanity checks, never as calculation parameters.
Comparable to roughly 7–9 economy seats, Amsterdam (AMS) → New York (JFK), one way.
6,315 km routed distance (great circle × 1.08 uplift) · 1.00 t CO₂ per seat · published reference factor, not an observation.
The per-guest comparison against cruise-ship intensity is shown once, at the top of this page, using the 13 published maximum guest berths listed under Capacity.
Only the segment actually observed is shown. Gaps are never interpolated into a continuous voyage.
Three separate measurements. They are never merged into a single coverage figure.
- Observed — AIS position reports relayed by the terrestrial and satellite providers in the snapshot window.
- Published specification — builder and registry data for length, tonnage, engines and capacity.
- Estimated — fuel, CO₂ and market value produced by model EMISSIONS_V1_FIXTURE.
