Fuel log number crunching

We first used Badger (30' Sundowner Tug) in early March this year and filled up the tanks yesterday, so I decided to crunch the numbers.

We put 178 hours on Badger's 100hp 4JH2-UTE Yanmar engine, and after yesterdays fill up to put the tanks back to full we used 1022 litres, or 268 gallons of diesel. So the way I figure it (always a mathematically shaky proposition) we averaged 1.5 gallons per hour overall. This includes farting around after crab traps, anchoring, docking, and our 7 knot or so cruising speed.

The PO installed a third smaller fuel tank, so we can hold 140 gallons. Yesterdays fill up was our largest at 92 gallons, which left 1/3 in the tanks. After a bit of head scratching, I figure that gives us a range of about 425 miles on 2/3 of the tanks.

Good to know

Yes, good to know and it's real info from fillups and running. You have enough range to travel anywhere on this coast without worry. as long as you keep tabs on fuel use and fuel stops.
