On some of the larger twin screw steamers the propellers are made up of individual blades bolted to a hub. Having stripped the large nuts we put a shaped charge around the shaft and blew the props off. We were then able to lift the blades separately. Photo of a blade coming over the side.

You had me lost with using a shaped charge. Not something most of us remotely have access to.

Shaped-charges? I want to take that specialty course.
 
The potential uses are endless, if not illegal in a lot of cases. Bank vaults, tree felling, bridge destruction
 
Is this one of those things where you go outside of the dive shop and hire your own specialty instructor privately?

Self-study? Here's the manual and the handy reference card. You're on your own for the supplies.
