Joking aside, safety requirements for most modern yachts dictate a manual bilge pump be fitted - to avoid exactly the scenario quoted above. Is this not the case for something like the HMS Bounty?
Well, I would liked to have a question answered and I am sure it will be answered on the investigation:
In 1998 the main pump was a diesel one and they had two auxiliary electric ones.
Now, for what I understood (by photos taken recently, by a sailor that had visited the boat and even by what was said by Bounty organization) they had the two electrical pumps as main, powered by two generator and some kind of hydraulic pump powered by the engine.
Why was not the main Diesel pump replaced? It was replaced by an hydraulic pump run by the engine? That does not make much sense since a main pup should not be dependent from the ship engine to be powered.
