Fuel tanks...again

Has anyone had experience, or know of anyone who has, of building fuel tanks from NPG resin. In particular, using the hull void directly as a tank.

Cheers. JW

I can't imagine why you would want to build the tanks into a boat using the voids, but some boat manufacturers have tried it in the past with varying degrees of success, and failure.

I know Michael Frode tried it for a while, and I believe Velocity have tried it also on their race boats.

I'm also doubtful that you would be allowed to if complying with the RCD.

As for Tek Tanks, I think they only build water and diesel tanks.

The tanks that Tec tancs can help with can be moulded to your hull shape.He will advise on rcd,as they supply most large boat manufacturers in U.K. I believe that you may also have a problem with this route, as it will need pressure testing and certification of compliance for rcd or mca codeing.
Flexible tanks may be an alternative,if so let me know as I may have a good contact for them.

I am assuming diesl is the requirement here.?I have no imformation on regs for petrol.

This is an interesting idea, I mean some ribs use water ballasting in the hull void so fluid sloshing around in some boats is okay, I suppose you would have to have a bulkhead or two to cut down the slosh factor, but the intergrty of the hull void is the problem.Does your hull have a drain bung ,how would you vent the fumes and keep water out and how much condensation builds up in the hull normally.Does the bung let water out when you open it in other words is the hull water tight cheers and good luck gavin
