Carrying extra fuel for longer trips

My Catalina 22 has a 6hp Tohatsu outboard that uses 1/2 gallon per half hours. Currently I have 2 3 gallon tanks. One is kept in the fuel lazurite and the other sets in the floor at the back of the cockpit which always seems to be in the way. I would be interested in seeing what other people do to handle this issue. I was thinking of storing gas containers up by the mast between the mast and the shrouds . Let me know what you think.
Thanks

This is the most common way I have seen to sail with extra fuel cans.

The newest fuel cans can lay on the FLAT and not leak. Two point tie down on Centerline of you boat. Two stacked on the flat = 20 hours.

Here is my setup for a trip to the Bahamas on my Oday 25. It uses about the same amount of fuel per hour as you stated. I had a 6 gallon can in the cockpit and 4 six gallon cans on deck. Had no problems with this setup. I did not store any fuel in the cabin or under the cockpit.

You could always hang a couple of cans on the transom, like the spare tire on a jeep.

We keep a six-gallon tank in the fuel locker, with a five gallon gas can at the aft end of the cockpit floor if needed. It's a lot of weigh aft in an already stern-heavy boat, but I never could see carrying fuel on deck on a C22.

BTW ... 1/2 gallon per hour sounds like a lot. Are you running wide open throttle?

It was 1/2 gallon per 1/2 hour (1 gal / hr), but that still sounds like a lot for that sized motor.

I like electric because fuel can be replenished without going to a fuel dock. Even if the range per charge is shorter.

What SV Chickadee posted, is what I normally see done.

I use modified self-venting pour spouts & plugs with O-ring seals that don't leak, when I use gas cans like that.

What Sailm8 posted is consistent with the burn rate in my Tohatsu.

I get much better figures than posted with my tohatsu sail pro 6hp long shaft , at about half throttle I am at 5 knots or so, maybe you guys are running into some really strong tidal flows or currents. Course I use sails more than some Cat 22s I have seen.

Worst place EVER for the extra weight.
Please tell me more about that. I would think aft weight, when in a good wind, would counter the forward, bow-down tendency of forward pressure on the mast. I understand that one doesn't want the bow to come up, that changes the helm balance, but with people hanging davits and transom arches, etc. on sterns, the wider modern designs actually contribute to better floatation while adding weight aft.

I'm not trying to argue against your statement, just showing you why I thought it would be fine.

That only may help going down wind. On every other point of sail, you don't want weight back there. Most well designed hulls get more narrow as you get farther to the back of the boat. Narrow means less buoyancy. Most boats are designed for optimum weight along the rail. Officially my boat is best balanced with one person ahead of the stay, one or two people behind, and one person in the cockpit.

Isn't there another locker to stbd? (Pic)
Maybe investigate different tank dimensions to fit in other locker; Refill-jugs, not an exchange tank. Flatter one, or convert to multiple 1-gallon jugs, or a bladder, etc. Plastic tanks are cheap.

I'm sorry, but the fuel up the mast thing is hilarious.
-You'd have weight bouncing around up there.
-Sun heating it up/expanding.
-What if it leaks. Especially with all the bouncing around and expanding.
-People would stare.

Edit: Wait wait, he's asking "up BY the mast". Not up the mast. :biggrin:
Ok, that might work.

Two words. Mass centralization.

Any fixed displacement should be close to the mast, and as low as possible. Any effort to move mass at the ends of the boat wastes energy.

Moveable ballast (crew) is a totally different story. We move crew all over the boat depending on conditions.

I will read up on it. Sounds like something worth learning more about.

High performance sailboats will do everything possible to get fixed weight out of the ends. Look at this view of the Sunfast 3600, an offshore racer. No vee-berth, just sail storage and a minimal head in front. NO anchor stored there! Aft, lots of open space, and then the spartan crew berths. Everything in the middle.
