I have a continuing fantasy about owning a 32'-38' trawler. One of the
common problems in a vessel of a certain age and price range are leaking
diesel fuel tanks. The proper repair is to pull the engine (the tanks
are generally on either side of the engine, requiring getting the engine
out of the way), and replace the tanks. The cost of doing this
approaches the price of the boat. Is anyone aware of a reliable method
of tank repair in place?

Any chance you could install a bladder inside the tank, more
or less like a racing fuel cell? You would lose some
capacity, but the price may offset this loss.
