This is a strange picture of the insulation behind the tanks on starboard side. In the aft/rear of picture is the fuel tank hanging and the new polyurethan insulation is in place. In the front is whats left of the insulation after I have welded new sturdy fastenings for the watertanks.
It will also be foamed around the tanks. Why should I heat up over 800 liters of liquid from inside the boat? And actually if water/fuel is cold then the warm inside air will turn into water and drip down below...
(Kind of odd to be so scared of water when building a boat.)
