I'm thinking of buying a Seawind 1000 catamaran, and they have outboard motors and the two fuel tanks hold a total of between 100 and 120 litres of fuel.
I realise that I should carry spare fuel when cruising, and I also realise that one must be very, very careful with petrol (as compared to diesel).
How do others who have outboards carry their spare fuel on their boats?
I remember seeing somewhere (maybe on this site) sometime ago a photo of a yacht that had a 15-20cm board/plank held horizontally between two lifline stanchions, and a few 20 litre containers (plastic, I think) tied to the board. This looked about the best I could think of.
Also, what are the pros and cons of plastic 20 litre containers versus the metal ones?
Answers to these questions - and any other information - would be gratefully appreciated.
Thanks
I cant't answer the storage question, but metal v plastic, I would go with plastic. I have done lengthly drivining trips with plastic jerrys on the roof of my car with no sign of deteriation from the sun. I don't think the metal cans would hold up too well in a seawater environment. The plastic does expand when hot, and whether it is required or not, I just crack the cap once a day to take the pressure off..
Thanks HG.... That much I knew, but how do you post the pictures here
Looks like I got the link wrong too 
But in anycase, to Relackson, in another photo, that basket on the back is lined with plastic jerry cans..
Thanks for your info. Toph.
As I tend to err toward the plastic containers, I was pleased to read what you said.
The ad. you referred me to is interesting - lots of containers; and in a novel position. But I see that the boat runs on diesel. I don't think I'd place petrol in this position - too close to the BBQ. It always worries me when I see a tender hanging of the davits with a petrol container in it - close to the BBQ.
We have done as you asked about and used timber strapped between 2 stanchions. Worked well.

When you reply or quote on the bottom beside the little smiley icons it says add image to message click on that and it opens a gate way to your pc you guide it to your photo folder and mouse click the one you want to up load to sea breeze

That is very neat F R and certainly works for diesel storage. The problem with storing petrol in plastic containers in the sun is they build up a lot of pressure with the petrol trying to evaporate off in the heat.
Whatever anybody does, do NOT store petrol in containers below deck.
that'd be the perfect place to store it if it wasn't the perfect place to store it if it leaked 
Argh...actually l am deceiving you. Those two red twenty five litre jerries are filled with diesel beside the seventy litres in the s/s tank under the cockpit floor. That is enough for hundred hours+.
My petrol is in the self contained transom locker behind the jerries with it's own ventilation and drain hole trough the transom - safe for gas bottles, safe for fuel - and l only carry five litre petrol. I guess, it would be safe for petrol too as the cockpit has three inch scupper on both side and it drains in seconds

Seawinds sail reasonably well. Why carry so much fuel? I use my yacht at least once a week and get through about 40 litres a year. I usually have to motor at least 20 minutes a day.
If your going to store that much outboard fuel, ensure you steer clear of ethanol.
By convention its yellow for diesel and red for petrol. Looks like Dama and sirgal need to swap jerrycans
FreeRadical, that looks like what I was talking about. Do you have any troubles with the containers heating up and expanding - although I'm assuming you have diesel inside them?
Dama, do you have petrol or diesel in those containers? Again, if petrol, I'm concerned about having it too close to the BBQ.
Ramona, I'm considering doing coastal cruising; so just want to be on the safe side.
Thanks to you all for your input.
Hi Relackson,
the photo was to show an option from Fleming marine.
I carry my fuel in jerry cans in front locker at present , but am looking at setting it up like the one in the picture , my BBQ is at stud end of transom and I will carry the petrol in the jerry cans mounted on the portside,

So what colour for water Frant? The clear white ones?
It may be convention, but it is not a legal requirement. While it is smart to follow established conventions, if you choose not to, then you need to tag the fuel containers with the relevant I.D. to ensure no mix ups when required.
the yamaha 9.9 4strokes on catamarans use about 1.2 liters
per hour per motor,so you have a good range with 120lts onboard
and the seawinds do sail well ,there are two crossing the atlantic
at the moment cheers ray

I agree. 120 litres is a lot of fuel. Adding all that extra weight with the extra fuel will reduce performance and economy and its a lot of petrol to worry about going off. The builders settled on 120 litres for a reason. Even though I see a few Seawinds with pot plants in the cockpit they are sensitive to weight like all cats.
It depends where you plan on cruising. My fuel tanks (Monohull) hold 220 Litres and going around the top I carried an additional 100 Litres.
It’s a long way between stops once you get north of Cairns and I imagine along the southern coast would be the same. Parts of North West of WA are also a long way between drinks.
Depending on the time of year and the timeframe you have you may need to run the motors for quite a few hours at a time.
120 Litres is not much more weight than your average adult male.
Of course if you are cruising up and down the East coast on weekends then there are plenty of places to pull in and refuel.
