Depends on your speed. If you motor at 5 kts., you need enough
fuel
for about 20 hours of motoring. I use about one gal. per hour.
So
I'd need another 8 gals.

Like to maintain a 4.5 avg. speed. Isn't one gal/hr. rather high?

Sounds like it to me. I'd guesstimate abouot a third to 1/2 gph.

IMHO you should bring along 6 extra gallons, thus extending your
range
by 50%. Especially since you already have the two 3 gallon jugs

Ok, now....where should I put them?
