In marine navigation the distance a vessel can travel without refuelling is called its fuel range. This depends on how much fuel the vessel can store, how quickly it burns that fuel, and the speed at which it travels.
The basic relationship is linear: the longer a vessel can stay underway (fuel capacity Γ· consumption rate), the farther it can go when multiplied by its speed. This principle is used by captains to plan voyages, schedule stops, and ensure safety at sea.
Mathematically the range (R) can be expressed as the product of endurance (hours) and speed (knots). Endurance is the fuel capacity (F) divided by the hourly fuel consumption (C). The formula is shown below.
