tanks for the help

My last RIB had a poly tank and that was buried under a deck and consol too and obviously involved alot of work to remove, as I'm sure stainless ones are on other RIBs. Does this make them "built in"?
Firstly grp tanks are no problem to diesel fuel. The grp minesweepers made for the navy have them but there enormous..

The us are having a few problems with grp tanks using Petrol as there adding ethanol and that.s making the tanks erode and disintegrate ..

Any tank that is NOT removable will be either built in or fixed in .
Fixed tanks can be removed by removing fittings and fixings.
Built in is usually inaccessible..

Thinking I was going to use grp as a built in tank. Then thoughts went to Stainless steel.

But now thinking of Plastic tanks Not built in but accessible..

I like the plastic tanks, my last RIB had a plastic tank which wasn't a problem at all. But I'm thinking that if you want anything over 120 liters then you might have a problem finding one, so it'll have to be in Stainless or Fiberglass. My Fiberglass one is 200 liters and the largest that Osprey build or used to build was 220 liters I think.

Thought it might have been!

I would be interested to see the spec on the materials they use for the tanks, they can't be using Scott Bader as a supplier!

We laid up the diesel tank in the boat - that way it fitted perfectly, and it would never need to be removed as all you would need is access the full length of the tank is remove the lid, you can then clean it and work on the pick up etc.

Tek Tanks only cater for diesel and all the petrol tanks are not custom made, so you have to make do with standard sizes. We have always stuck with aluminium, as in race boats the extreme use tends to crack the harder stainless, I would be happy to put stainless in a leisure boat though.
