4. Marine fuel management - Wikipedia

   en.wikipedia.org/wiki/Marine_fuel_management

   Many marine vessels do not provide a way for captain and crew to measure and monitor fuel usage while underway. An optimum system onboard would include the ability to instantaneously monitor fuel burn rates from the wheelhouse. Individual engine and generator burn rates would be included, as well as fuel tank levels.
