@nugent - any booth would do me :-)
Few bits of progress,....
Cut out more of the deck to fit in the double fuel tanks. Routed the under deck conduit (that was a nightmare), 4 double skin bulkheads to get the old one out of, then i'd only gone and bought a new one that was 4mm wider
About 4hrs of dremeling and having to cut lots of holes in my deck :-( it was out and the new one in. Brute force and 3 men :-D
Anyhow, next was to reinforce the deck, make the recess for the fuel tanks and then seal everything up. All came together pretty nicely in the end, tanks in place, and all sealed up, will need few more coats of glass to level everything off. I'd ideally like to re glass the whole deck, but i cant find anything suitable to attack this black stuff. Just taking out the little patches on the rear of the deck destroyed 4 50grit discs on the grinder and took about 20 mins.
