- • Approximation assumes comparable displacement, hull condition, sea state and engine efficiency. Separate hotel/auxiliary loads rather than scaling all daily fuel cubically. Daily consumption is not voyage consumption; trip duration changes with speed. Use measured vessel curves for operational prediction.
Important limitation
This is an educational estimate based only on the values and formula shown. Verify current rates, rules, units, and professional standards before relying on the result. It is not personalized financial or investment advice.
