Re: HMS Bounty in trouble...
If the ship was designed like most modern ships, the pumps are purely AC. The main engine turns the screw and nothing else. They probably had a GM 671 or similar genset for a boat designed in the late fifties or 1960. (just a guess) I say this because it sounds like this ship was designed like a tugboat that looked like a sailing ship, not an oversized sailing yacht as one would believe. On many large vessels, the bilge pumps cannot keep up with a hull breach. You rig up dewatering using the fire main and eductors. The problem is the fire main runs off an electric motor, too.
All the water had to do was knock out the switchboard, then it would all be over with. No bilge pump, no fire main, no way to survive a hull breach.
