My vessel is fitted with a 30l day tank which is filled from the main tank in the keel
. I purchased her from the builder
one month after launching however I whenever I am on a starboard tack at +15deg of heel I find diesel
in one of the port compartments under the floor boards. After months of searching I finally have establised , by pressurising the tank, that the leak is somewhere near the top one third of the tank. Upon draining and opening the hatch
into the main tank I find that the GRP hull
serves as the containment vessel. The surfaces are coated with what looks like thick blue gelcoat
Suggestions as to what I can recoat the inside of this tank with to ensure leak free containment ?
I have attached two pictures for clarity - A view down into the first section of the tank showing the inside contour of the hull
and a view into the second tank.
