I dimly remember an ad in a yachting magazine a while after the Sarah Beth was launched and commissioned. Apparently Burger put Deutz engines in the vessel as original equipment, and somewhere off the west African coast, one of the cylinders in one of the engines "went south" and was replaced at sea by the simple (?) expedient of somehow unhooking the piston's con rod from the crankshaft, sliding in a new cylinder "kit," reconnecting the con rod to the crankshaft and re-starting the engine. The Deutz ad made the process sound so simple that any reasonably ambitious sea scout could do it with his trusty Swiss army knife. I really would like to know how simple such a procedure really is.
