Nobody needs to know exactly what their gph is.
But it can be very useful to know approximately what it is.
I used my first trip to Alaska to determine my burn rate and it was loaded w irregularities .. but all of them were small or less. The biggest variable was including time running time (hour meter) at less than cruising speed but it was small too. A much smaller variable than w my typical cruising. So other than using time running at very low throttle settings my computations should be quite accurate. I came up w 1 gph. In the years after I compared my number to gph posted everywhere and was pleased to notice how close to other calculations on the same issue.
Most relative to the above is my cruising style. Much more casual than most here on TF. On a typical day I’m not sure where we’re going to anchor or tie up for the night. Most would be at least a bit uncomfortable w that. But I spend a lot of time underway surfing the GPS plotter for possible places to overnight.
Now that you're privy to my cruising style you can see how knowing my fuel burn accurately would not be valuable in great detail. But re the fuel burn (with 100gallons) and a burn rate of 1 gph very little accuracy is required. Fits my style perfectly.
It’s not totally uncommon for me to change course and go to a different destination. I only really know two speeds for my boat. Cruising speed and high cruising speed. 2300rpm and 2500rpm. Top speed? I really don’t know. I’m sure it’s very close to 7 knots. The only speed I really need to know is cruising speed .. 6.15 knots.
One place I can use a great deal of information w details is in TF posting. Often I go to the computer room to look up information. Like finding the name of places and correct spelling.
