Hi Ralph I've tried to track these down and I was only able to find two:
1. During the lowering of emergency cutter #1 it appears that they forgot to remove the gripes and then put enough weight of the boat on them that they couldn't release them. A crewman got an axe and cut away the gripes freeing the boat for lowering.
2. Walter Lord apparently found a newspaper report about a crewman who said he and another crewman had to chop away a sounding spar which was obstructing lifeboat #4 below after the boat was loaded from A deck. This story was not mentioned in any of the post-disaster hearings as one would expect. So this story is dubious at best.
