Fiberglass Fuel Tanks

[Garygee]

Hi folks

Thinking about increasing my range by moulding some fiberglas fuel tanks to fit flush with the deck.

My question though if I mould using polyester resin/CSM does the inside of the tank need to be treated to prevent attack by the diesel or leaching of anything harmful into the diesel.

Have had flexi tanks in past but given the volume find then hard to handle end fix in place, besides they leave the deck nice and slippy due to the leaks .

flexible fuel tanks instead of going to all the hastle of glassing them in. I believe you can get them made to measure or simply off the shelf to hold in excess of 50 gallons. Of course you'd need the locker/under floor space for this. Just a thought !

I believe scorpion use resin fuel tanks, but it has to be a particular type of resin to withstand attack from fuel. I have no idea what type though.

The resin is an acid proof type which also resists diesel

I must say I prefer this idea as you can make it to fit your hull. With the constant flexing, stainless steel will crack eventually unless you make it rigid enough, which will add to weight. And what about electrolysis? I presume aluminium will suffer from the same problems, apart from weight.

Now, before you go thinking I'm a clever sod, I've just got an encyclopaedic memory when it comes to boat stuff. This is a jwalker bit of info. Do a search on the it, or on the word "molecule" here on RIBnet. http://rib.net/forum/showthread.php?...cule#post34286

Thanks folks

I plan to have the fuel tanks as part of the deck wrapped around the console, in effect bringing the step up into the bow back a bit.

Give this they will be open and often walked on.

All the fuel tanks i have seen like you say or designed to go into somthing to supply support. These tanks will have to be strong enough in their own right.

Now its just a matter of finding somwhere that sell the stuff and checking the binging in CSM is compatable.


Thanks Gary
