Quick answer
SkipperCalc has 2 sourced Altamarea configurations in the picker. Use them as a starting point when you do not know your exact fuel burn, and replace the figure with your measured burn when you can.
- Altamarea Storm 46 · 3 × Honda 3 x BF350A XDU/UDU/XCDU
- Altamarea Wave 23 · 1 × Honda BF150D XDU
Practical rule: compare L/nm or €/nm, not only L/h, because speed changes cost per mile.
Calculate with a listed configuration
Open “Choose my boat”, select the brand and model, and the calculator will use interpolated fuel burn inside the published speed range.
