adding extra fuel tank in A mkII

Has anyone added a extra fuel tank? Maybe 10-20 gal. If so where did you install it.

I have seen one installed in the back cabin, where the back half of the mattress usually is. There was a deck fill in the cockpit floor. ​

I would not install another fuel tank in my boat. Just another thing to leak, be maintained, keep an eye on . . . and it will necessarily be buried in a deep corner somewhere. Most people who need extra fuel capacity affix a 2"x6"x8' board to the stanchions and lash jerry jugs to it. You can get 20 gallons in four jerries; only fill/carry 'em when you need 'em so you don't have stale diesel growing algae inside the boat; put a freshwater jug on the rack, or two, or gasoline, or any mix of jugs; easily sell/trade/donate fuel to someone who needs it; .... much simpler, easier to maintain, more flexible to use, and less expensive. As a DIY boatowner/sailor. those are the things I consider long before convenience!

I guess I wasn't very clear about my needs. I want to put the extra fuel below deck and as low as possible. I do plan to use Lee boards for fuel and water. I'm thinking 4 five gal fuel and 4 6 gal water.
On deck.  Anymore than that I'm worried about weight up high and the transfer of fuel in rough seas.

Putting a tank in the aft cabin would be the easiest way to go. I'm concerned about adding too much weight aft. I plan on having a lot of other heavy gear aft. Scuba gear and spares on and on. I would like to keep the boat balanced and put the weight on the center line if possible.
My current thinking is using the area under the V-Berth?
I've seen V- berth tanks that might work. Might make a tank for the V- berth.
I'm just looking for ideas at this point.
If it been done before, I would like not to reinvent the wheel.
Thanks again as always.

Are you going to replace the water tank up front?  On my trips water was much more of an issue than fuel.

Adding weight to the bow is would be less desireable than adding it to the rail and why folks use backer boards.  You could put two on each side and skip a whole lot of heartache to get 20 gallons of fuel.

What I was thinking is 20 gal of fuel and 24 gals of water on rail. I was looking for another 20 gals of fuel storage inside somewhere. I wanted a total 65 gals of fuel. around 100 gal of water.
I want to keep the fwd water tank I'm also dreaming about a water maker in the hell hole port side aft.
I was thinking about the storage area around the fwd water tank. Even removing the 3 small drawers under the V-berth.
At this point I'm just dreaming/planning.

Chuck. I am curious what your dreaming of where you are headed. I presume islands somewhere. In our 1990 where the drawers under the v berth is that is where our depth and speed translucent is located. I believe many 36's have the same. For us the 6 gallon jugs we carry atop is the most simplest way. We burn about .75 gallons at cruising speed so that is over 35 hours of cruising without adding fuel.

Well at this point I'm soft on Three plans.
Plan A. Head south to Cabo San Lucas and up the Sea of Cortez .Doing the HA HA.  Fuel is less of a issue than water. I'm watching how things are unfolding with Mex. Government. Things are still unclear.

Plan B. Head up the coast to Seattle then Canada. This is where I have serious fuel concerns. The trip at best is a motor sail, uphill, big swell and waves. Going off shore is by far the best way to go. North of San Francisco ports are far and few between. Coming in for fuel can be dangerous and cost a ton of time. Trying to time refueling is really hard. Very long legs, tons of Lobster traps, bars with breaking waves and no way do you want to do this at night. Plus the fuel docks are closed.

The main reason I want fuel inside the boat is adding fuel from cans in a big seas is not ideal.

I have done this before in a bigger boat and have it was one heck of a ride. Took 10 days came in fuel twice only.  We carried 165 gals fuel. We Avg between 3 and 6 knots. Freedom 44. 900 miles of Fog!

Plan C put on a truck and ship to PNW.

After reading my own post, I'm leaning away from plan B.
Still dreaming!
