Carver 326 on Great Loop

I am considering the great loop on a Carver 326. Does anyone have experience with this model ( twin 300 hp gasoline)? My main concern is the*fuel*range, specifically on the leg from Hoppies Marina to Kentucky Dam. This leg is 160 miles downstream on mississippi and 60 miles upstream on Ohio river. The*fuel*capacity on this model is only 162 gals. How should I factor in the advantage and disadvantage of the*Mississippi*and*Ohio*river currents in my fuel calculation. Considering to bring additional 25 gals. Of fuel in jerry cans. Any knowledge and information will be appreciated.

Re: Carver 326 on Great Loop

Here is a break down of the fuel needed.

Fuel - your boat must have a minimum fuel range of 250 miles.
This is the farthest distance between fuel stops if you take the Tennessee-Tombigbee route. So, unless you plan on
carrying additional fuel in jerry cans, your boat's fuel tank(s) capacity must allow you a cruising range of at least 250
statute miles.

NOTE: (optional route): If you plan to cruise the Lower Mississippi River route to New Orleans:
Your "diesel powered" boat will need a cruising range of 376 miles.
Your "gasoline powered" vessel must have a cruising range of 450 miles.

Re: Carver 326 on Great Loop

You need to figure out MPG at different speeds.

Odds are if you drop back to 6-8mph, you will have upwards of 2mpg but you need to confirm. That would give you over a 300 mile range

Once you know you mpg assume maybe a 1.5 mph current on both rivers (conservative).

Lets say 2mpg at 8mph:
- Mississippi: You will actually be making 9.5mph for the 160 mile, that works out to around 17 hrs and you will be burning 4gal/hr, so figure 68gallons
- Ohio/Tenn: You will be making 6.5mph against the current for 60 miles, that works out to around 9hrs at 4 gal/hr, so around 36gallons.

Total around 104gallons burnt.

While you are probably fine, MAKE SURE TO CHECK YOUR ACTUAL MPG and update the calculations and make sure you have a buffer.

Re: Carver 326 on Great Loop

Key word is BUFFER, meaning keeping a RESERVE fuel supply.
These boats are hard to paddle so you don't want to let you fuel tanks get close to empty without a fuel dock in sight.
MPG will vary with engine tune, wind, current, condition of boat bottom and operator impatience.
My heavy 28 with twin EFI 350 Marine power engines and similar boats belonging to friends averages
between 1.0 and 1.15 mpg at a 25 mph cruise. So, slow down and enjoy the trip.
