Fuel-share estimate

Multiply hours under way by a burn rate and a fuel price, then share the cost. This is an estimate from your numbers, not a quoted surcharge.

The formula

Litres = hours × litres per hour. Cost = litres × price. Share = cost ÷ people. Four hours at 30 litres an hour is 120 litres; at $1.50 a litre that is $180, or $45 each for four people.

Real burn rates depend on the hull, the load and how fast you run. Use a figure the operator gives you, or treat this as a planning range. Some charters include fuel in the fee; others settle it at the dock. Ask which applies before you travel.
