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.

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

Well Scotty, I guess you'll just have to let them roll about on the deck between the coach and
the toe rail (along with your bumpers), I know this because I have been informed by reliable sources,
(Chuckles and BB) that lockers are not to be used for stowing things.

Cheers

Scot,

If you are going to carry extra fuel in Jerry Jugs. CARRY THEM ON DECK!!
Tied to the stanchions or some where a spill will go to a scupper. A
diesel spill in the cabin will give you a smell for an awful long time.

I got a big boat.






Pathetic Earthlings! No one can save you now!

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

Ole Thom

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.

Don't know Thom, that's why I'm asking here i filled up last time out
and took on almost 5 gallons, that was for the season. I don't motor
much, and I plan on sailing, but I want to have a back up, just in
case.


Scotty

Scott,

5 gallons is just about what I use for what you would call a Sailing
Season but I leave my boat in year round and on those nice NW winter
days I sail. I motor sail for two reasons; 1 Two get cabin heat from my
Red Dot heater and
2 To get rid of the fuel I put in, in the Spring

I have a 20 Gal fuel tank and more often than not, I'll have a 1/4 tank
left come spring. This I pump out in the spring. I give it to the live
aboard ten slips down from me for heating fuel.

I fill the tank each spring, hoping to fight condensation (?) I have a
filter/liquid trap but an active tank seem to work best for me.

With you pulling your boat for the winter, that 12 Gal tank was well
thought out.

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

I have done 75 miles using about 7 European gallons on flat calm. US
gallons are about 10% smaller.


Your tank should be big enough, but I'd carry a couple of extra gallons just
in case.
