Range is only part of the issue. Most cruisers run the engine 2 or 3

OK, use your numbers.

Assume only 10 gal in the tank and 3 qts/hr consumption.

(10*4)/3 = 13+ hours.

If you haven't found safe haven in 13 hours, you are probably in deep
doodoo.

Ran a 30ft sloop with a one lunger and a 10 gal tank for years.

Out on a 2,500 mile cruise, it was a big deal if I bought 6-7 gallons
at once.

That's why those boats have rags, so you DON'T have to listen or smell
the damned engine when you want to go someplace.
