How much fuel should I carry if I want to be assured of motoring (in
case there's no wind) non stop for 100 miles? 30' boat, disp.
#7,500. Yanmar 2GM20. I have a 12 gallon tank.
TIA

Small yanmar guestimate of 1/2 gallon an hour, make maybe 5 knots...mmmmm
lets see 12 gallons good for 24 hrs, about 120 NM range....
I think you can go 8 hours and maybe 50 miles if not too much bad stuff
happens....thats how I would figure it and then maybe you can get back where
you started.

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.





Pathetic Earthlings! No one can save you now!

You must show your work!

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

Scotty

Sounds good. I'd rather not carry extra fuel, but I do have a pair of
3 gallon jugs that are compact size.

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

Scot,

My 2cylinder Universal (18 hp approx) does 6 knots an hour on a little
over 1 Quart. At 4/5 knots, if not bucking a tide or a stiff hedwind,
I'd say you'd need about about 26 quarts or 4 Gals.

What is your motoring range for your boat with the 12 Gal tank? Should
be in your Sps? I'd say that they gave you a 250 mile cruising range
with power

My 2cyl 20HP Albin diesel will push my 31'6" 6 tons longkeeler at 4.3
knots using one liter per hour at about half max rev in flat water.
That would indicate that you could do the same or better than 3.8x4.3
=
16.3 mil per gallon. 12 galons should give arround 190 nautical miles
if you run the engine at the most economical speed, probably 4-4.5
knots if your bottom and prop are clean.
