Following my previous thread about replacing the corroded aluminium diesel and the negative opinions concerning stainless steel tanks I have made a decision. First off I was thinking about a steel tank. I know these are fine as my last boat had steel tanks for 27 years and no problems. This tank will be 'Vee' shaped so I thought about a 4mm bottom to accommodate corrosion from water laying in the bottom and 2mm sides and top to reduce weight. Then I realised that the lightest tank will be no tank at all!
So I'm going for a built-in GRP tank formed within the longitudinal stringers, aft bulkhead and a new forward half bulkhead. Ahead of this I will be building in a smaller water tank so weight will be kept to a minimum. My boat before last with GRP tanks is still around with no problems. So that's it. Cheap and cheerful and light weight.
Setting up a large extractor fan tomorrow to clear the fumes from the compartment.
