ive never tried it but your on the money, im sure someone out there will know how to store em

 that is your best bet, that way you can distribute the weight evenly around the boat. to put the fuel in the boat , just use the spout provided on the cans unless you have the steel ones and then you can either syphon or just get a funnel

jerries are good for weight distribution and removing the fuel once you get to your destination (depending on where you are going). Down side is if you can't remove them from your boat (either full or empty) they will get in the way and send that lovely fuel smell through everything.

There are fuel bladders available that are good because once emptied they can be rolled and stored ina  small space. Downside is they aren't mobile when full.

As for transfer, one of those siphon tubes with the ball bearing is by far the easiest in my opinion.

Where you going?

 the jiggle siphon hoses are the best way to transfer without spilling that we have found over the years.We had to leave jerries onboard once and decided after a couple of days of tripping over them that we would make sure we had no fuel in them and tied a loop of the  anchor we were using of a night each morning when we left.Makes it very easy to find your float as well(not recommended for areas like the abrohlos)

two jerry can holders which both hold three jerry cans that clip to my bow rail! with all the weight you usually have at the rear this works a treat for me!! keeps them off the deck and out of the way! my fill point is also at the front of the boat so its very easy to decant into the tank!! i use the jiggle siphon too

Bladders are self priming, just sit on it to get it started.  Fold and store when empty.
 

i just bought some stainless steel rod and bent it into shape!

There is a hand pump for fuel that comes with the same screw top that the plastic petrol cans have, so it screws to the top of the container. MEY is one place where it is sold. Fits the 25 lt can. Or just buy a spare fuel line c/w priming bulb and use that to do the pumping.

Was wondering if you have done your trip to cone bay yet?

na mate,going mid may. cant wait

Take jerries- once empty they weigh bugger all, strap them on top of your T-Top providing it isn't already loaded with gear. Siphon hoses are the go, when buying them get a heavy duty one with extra thick hose- you spend less time refueling then. The ones with smaller diameter tube take ages to empty a jerry.

for pumping spend a few dollars and get one of these crank hand pumps

safe, no spillage and used by most small plane users at remote airfeilds.

as for storage, bladders are easier, go with 4 x 50lt each and that way you can roll them up and store when finished. Also easier to move the weight around when balancing your boat.

Jerry cans are ok, but I'd not use a funnel or try and transfer fuel with a motor running in a swell etc with funnels.

Rather go a hand pump.

where do you get these bladders from Tony? I checked out the turtlepac website but it wasn't very useful.

most bulk chemical places have them, just ask for a industrial hydrocarbon and ethanol suitable one. Nice thing about them is you can get fuel line fittings put on them as well, so removing the need to decant and just rather plug into your engine on a spare fuel line.
