In my "Sail Army" days, a Mk VIII LCT (ocean going tank landing craft, carried 4 rows of 3 tanks) with a hard chine hull, developed a split on the bottom corner where side met the flat bottom. (no great problem we had 36 ballast tanks and could double as a floating dry dock for smaller craft) It was repaired with 5 gallon drums of Araldite while we were dryed out between tides in Benbecula. (Outer Hebrides missile range) As far as I know, it was still holding when the ship was sold for scrap 12-15 years later!
"Araldite sticks just about anything to just about anything".........including ship's hulls!
I think just about all you couldn't do with Araldite was stick weld it! Machined beautifully, took a great thread, moulded around chicken wire and newspaper to form any shape for any use you wanted, including condenser bell ends and centrifugal pump casings. It was, however, very expensive. Your tax dollars at work!
Incidentally, for a peek at life on an Army LCT running to St, Kilda in the '60s read Atlantic Fury, by Hammond Innes.
