Regarding whether the boat yard workers know their job is a red herring and may apply to those yards that use individual sticks to prop a boat up and a small number of boats to attend to. Dry sailing yards (thousand boats in the Ionian) launch and haul six days a week most of the year. How on earth you expect a boat yard worker to know the position of all bulkheads on all boats is not practical considering the enormous variety of size and construction. They have enough to worry about regarding props, outboard shafts, and impellers to spend time searching through a database about the position of the bulkheads. The (Bavaria) hulls that split were propped in cradles These cradles have very limited adjustment and are positioned for security in high winds and a possible earthquake. The boat "trailers" used to launch the boats have their support chocks variable to a degree but again the position is elated to security and balance.
If one wants complete protection against errantly placed hull supports a liner is going to outperform conventional ribs every day of the week. That said, all sorts of boats are damaged in yards every year; only the insurers will have the complete stats and it's a bit misleading to try and draw inferences from the odd anecdotal tale here and there.
