Q & A

Fuel consumption

We have a new 58Ft. narrowboat fitted with a Barrus shire engine 45Hp. and were wondering what kind of fuel consumption to expect.

Fuel consumption does of course vary according to your speed, hull design and any other appliances you might have fitted on board. But as a rough rule of thumb, you can expect around 1.5 to 2 litres per hour.

It is also possible to download fuel consumption curves from the manufacturers website. These tend to err on the conervative side (suggesting higher fuel consumption) but is a good starting place! You could also fit a diesel fuel meter- though it means breaking into the flow and return pipes (as not all of the diesel drawn by the fuel pump is actually used- much goes back to the tank- quite warm) so the sensors have to work out the difference, and account for expansion due to heating. This means they are not cheap- but quite common on posh seagoing craft!
Otherwise, go with Richards 1.5 to 2 litres an hour!
