9.6.13 Fuel Management

Maretron fuel management products are designed to

be accurate and reliable; however they should be

used only as aids for fuel management and not as a

replacement for traditional fuel management

techniques. BEWARE: Conditions can quickly

change that drastically effect time and distance to

empty.

You should not use the fuel management data types unless you fully

understand all the parameters associated with fuel management. All

fuel tanks and all engines must be included when setting up N2KVIew

plus there must be accurate fuel rate sensors installed on the vessel

and accurate speed information in order for N2KView to properly

display fuel management information. You should also note that fuel

levels may contain significant error if the boat is not sitting level in

the water (i.e., sailboat heeled over or a power boat riding bow up

won’t necessarily report the correct amount of fuel). Even when setup

correctly, N2KView should be used only as an aid and not the sole

source for fuel management information.

NOTE: These functions are available in the optional Fuel Management Module. If

the Fuel Management Module is not licensed, the component will display “Not

Licensed” instead of data values.

The Distance to Empty and Time to Empty measurements are calculated based

on the conditions that are prevalent at the time. Changes in wind and current

can drastically change the Distance to Empty and Time to Empty measurements

that N2KView calculates and displays.

For example, if you are motoring 100 miles out to sea with the current, at the end

of the 100 miles, N2KView might display that you have 120 miles before you run

out of fuel. If you then turn around and start heading back to land, this time

against the current, the Distance to Empty reading may change to 80 miles.

Therefore, you must always keep in mind the direction and speed of prevailing

winds and currents. You must always remain aware that N2KView makes

Distance to Empty and Time to Empty calculations assuming that your course

and speed, and the prevailing winds and currents, and any other factors that may

affect fuel consumption will not change.
