Surely that's a non-problem?
Around here the gas
dock attendant ALWAYS hands the nozzle to the
skipper - or a trusted crew
member. The reason is simple: If there is a spill - or if gasoline goes into a diesel tank - the gas
dock man can yell "It wasn't me!"
So as you - the
skipper - stand there with the nozzle in yer 'and, you can't see your fuel gauge anyway, but you can hear the gurgle of the fuel going down the filler hose change
pitch as the tank(s) fill(s) and the fuel begins to rise up in the filler hose. Stop there if you have lotsa capacity. If, like me, you don't, go DEAD slow till you actually see the fuel near the top of the filler.
I always keep an
engine diaper handy in case I should blow it, but why would you blow it? As skipper you're sposed to be on the ball! I wrap the diaper around the nozzle as I return it to the dock man. Not even a
single drop gets spilled.
How do I know how much is left at any given time? Well, I don't really. I know that I burn 2 litres per hour at 2,400
RPM. My hour-meter readings, noted in the log, tell me how many hours since the last fill, and therefore how much I've used. I plan to press up, and usually succeed in doing it, before I'm down to the last 20 litres of my total tankage of 60 litres.
