How much compressed air would have saved the Bounty?

A dim question, which I'll drop immediately if asked.

So, the replica Bounty seems to have sunk because her machinery stopped when it was most required; she lost motive power and pumps.

Not by any means the first such vessel to founder in such circumstances.

Are non-standard vessels with creaky timbers/fatigued steel, not under the same insurance-assessors' scrutiny as yachts? If they were, wouldn't the antiquity/maintenance of their machinery be condemned, wouldn't replacements be required before taking kids offshore?

If there's any chance of pumps being overwhelmed/inadequate, or of the vessel's design (I mean, some singular traditional characteristic) being especially vulnerable to catastrophic breaching in terrible conditions (thinking of the deck hatch aboard the Marques)...

...would there be value in CO2 tanks, triggered automatically or manually, to fill chambers with tonnes of buoyancy below decks? Needn't be obstructive to the ship's running when not deployed, but would be certain to delay sinking, or even save the vessel in extremis.

Surely if taking dozens of students, particularly clueless teenagers, into genuinely dangerous situations, every possible measure should be included to prevent a vessel's loss?

Otherwise it's like loading a 1920s charabanc with kiddies, then rolling away in heavy traffic - wouldn't be encouraged, would it?

(I tried to incorporate the phrase "Ncap-sulate" there, but couldn't... :o :rolleyes:)
 
I don't quite understand what you're suggesting here. What "chambers", and what would they be full of before the CO2 went in?

They'd be like ruddy massive rubber rafts in the cabins, which would billow forth when the water threatens to flood the ship...

...hmm, it didn't sound terribly practical, even at first. I suppose an inflatable chamber of reasonable robustness, big enough to obviate flooding in the saloon, would fold down into a valise the size of a large garden shed :o...

...as promised, I'll drop it at once.

Airbags on cars are not like massive rubber rafts, not on mine anyway. You could fit quite a few without taking up too much space in the cabins, and I think they are electrically triggered.

Of course it would never work because no-one believes the craft is at risk in this way. After all they had professional skipper to take care of it.
 
Are you saying she still had the original 18th century diesel engines?

Silly boy! She must have had steam engines. :rolleyes:

I believe this sunken Bounty was a replica, built for the 1962 Brando film. But it wouldn't surprise me if the systems which failed, were original in some respect, to that time. Not that fifty-year old engines can't be good, but those on the Bounty clearly let her down.

I've no idea, but large diesels, I believe, generally have issues with heeling so it may not have been down to 'antique' machinery.
 
I think I read of the skipper admitting that the engine was much smaller than was ideal aboard this size of vessel...

...and something I read seemed to imply that the machinery wasn't in best condition. Sorry to be so vague.
 
For some time I have been thinking about the effect of installing car airbag type devices below decks in locker spaces etc on a small yacht as emergency buoyancy-fired off when everyone is on deck to stop vessel sinking!
I am suprised that a vessel like the Bounty wasnt fitted with sealable seperate watertight compartments usually insisted upon even on quite small charter vessels?
 
Bounty (the original) pre-dated steam engines, so your old Dad is maybe not as old as you fear :)

Sorry, she didn't! HMAV Bounty was built as a merchant vessel in 1784. Newcomen invented the steam pumping engine in 1712, and Watt made it more efficient by 1775.

I will agree that steam wasn't successfully applied to ships until the Charlotte Dundas in 1801, though the earliest efforts by the inventor (William Symington) were tested in about 1788.
