How efficiently the fleet runs — litres burned per nautical mile, by captain and by vessel, from the trip logs.
The core view
Each bar is a captain; each coloured band is a boat they skipper, drawn at its real economy (litres per nautical mile). The efficient boats sit in front, so a thirstier boat shows as a band rising above. Lower is better. Hover any band for the number and trip count.
Fleet-wide fuel economy per vessel — the boat, not the driver, sets the baseline.
Fuel over time
Total litres burned each year, stacked by vessel. Fleet-wide fuel logging began in 2021; 2026 is partial (through Sep 8). Hover a band for that boat's litres.
Efficiency over time
Fleet-wide litres per nautical mile each year (total fuel ÷ total miles). Lower is better. This moves with the mix of boats run as much as how they're driven; 2026 is partial (through Sep 8).
By captain
Overall figures per captain. Note: a captain who mostly runs the big boat will show a higher overall number — that is the boat, not them. Compare like-for-like in the chart above.
