Most boats and ships I have worked on did not have fuel gauges, though they could meter the amount of fuel that an engine or boiler consumes. We sounded the tanks with a sounding tape and measured the amount of fuel in the tank. On some vessels we can meter the amount of fuel we transfer to the day tanks. And on others we sound carefully as we transfer the fuel. But Never have we ever ran out of fuel. We do pay attention to the fuel consumpsion and use those figures in our voyage planning with a fuge factor of about 10 to 15%. Pending on our mission. There are times when we have to figure in fuel usage when operating on station. Either as a fishing boat, research vessel, Oil field work boat and many others in the wide varity of commerial usages of sea going vessels.
But a delivery Capt(?) should know how to work the math to figure out fuel usage and the amount of fuel needed to deliver a vessel. And more importantly know if his/her tanks can hold enough fuel or does he/she need to make refueling stops along the way and those stops should not be more then 3/4 of the max distance of your tankage. (Some people fail to figure in currents also.)
But that is why we put sails on boats right?? So we don't have to listen to those engines running 24/7. Now a Generator may be a different story.
Where are my ear plugs....
A hint, Sound your tanks weekly even if you do have fuel gauges for those tanks... Hey the gauges are man made and are not always fail safe. And keep the Tank tables on board so you know that when you 15" or 2'3" you know what the gallons/liters really are.
And if you don't have tank tables. Well? Use your math and make a set of tables for each tank.
