    Hi Jock,
    "Compressed air sounds complicated for a model unless you find a 12V compressor ..."
    You'd need a pretty big sub/ship to fit a compressor in!
    As far as I know folks who use compressed air only use the compressor to charge an on-board pressure vessel. Meaning of course a limited number of 'Surface, blow all tanks'.
    Er was that the 5th or 6th dive?๐Ÿ˜ฎ๐Ÿ˜ญ

    Having investigated various methods for diving/surfacing I opted for the piston tank, which'll work until the batteries are flat!
    So that's what I've bought for my Akula II sub, ca 1m, which I hope to finally get operational this winter.
    Guess I'll have to build a vertical version of Martin's 'Big Blue' tank to test it ๐Ÿ˜‰
    A slower version using pumps should be adequate for a 'Heavy Lifter ship'.
    Seen various docus about them and they don't seem to react too fast.
    Especially when coming up with several thousand tons of load aboard.
    My post was only 'tongue in cheek' anyway - unnecessarily complex just for removing ballast.
    Would be fun though watching the ship rise.
    Don't let the Coastguard see you though - they might think you are illegally flushing tanks at sea๐Ÿ˜ Good luck with your dream๐Ÿ‘

    Just a standard fish tank air valve. As you are in Canada the suppliers in the UK would not be useful, but I'm sure you have suppliers in Canada. Try Googling "Air Line Control Valve Aquarium Fish Tank". You could use several on a larger model.

    Wondering what kind of air valve you used? Is there the kind where a small float will seal the valve preventing water form exiting on top? Would be ideal as pitch could push water out fore or aft.

    If its a choice between lead and water the logic is perhaps understandable. Large model hulls displace a great volume of water to carry essentially an open space full of air.
    A fellow modeller had built the large Puffer I had and used exactly the same tank with a sealable air vent. My first attempt was to use a sealed container using a pump - bad idea the puffer listed badly when I used the rudder and would not self right.
    I suppose you could emulate the real size and pump water into different tanks but using an open tank removes this problem and with two watertight compartments running fore and aft on port and starboard stability is not a problem.
    Doug, the comments re the Starship Enterprise are classic and brought a smile. If we had their technology I doubt if slots in hulls would be required.
    I'm off to "Boldly go"

    Couldn't open video files. I got myself a new MacBook and having had only MS Laptops before not quite familiar with all download functions.
    Compressed air sounds complicated for a model unless you find a 12V compressor with enough power to blow out the ballast tanks but 1 or 2 12V pumps should do the job.

    Ref The MV Derbyshire,
    Jock; look out for the TV series 'Disasters at Sea', called 'In Seenot' where I watch it here in Germany, sister series to MAYDAY Alarm in Cockpit which investigates aviation accidents.

    "I just have a big slot in the bottom ..."
    Ooh naasty!๐Ÿ˜ฎ (As Sub Lt Phillips would say).
    You know, funny (peculiar) when you think about it!
    Here are most of us doing our best to seal our boats and ships inside and out to prevent ingress of the wet stuff at all costs and efforts.
    And here are these guys deliberately poking 'oles in their models and doin' their best to sink 'em! Takes all sorts I s'pose ๐Ÿ˜‰

    Seriously though folks ๐Ÿ˜ sounds to me like they need something akin to a submarine diving tank, piston tank perhaps or compressed air driven? (Soda syphon CO2 cartridges? Bicycle pump?)
    Such ideas have been rattling round in my nut for some months for a (stand-off) model of a 'Heavy Lifter' ship (such as used to transport oil rigs and similar) for use as a rescue ship for stranded models. A sort of motorised floating dock.
    Just a thunk,
    G'night all, stay safe.๐Ÿคž

    "I wondered with the gravity drain ..."
    Lt Cmdr Data -
    'Captain, decks 9 through 17 are reporting injuries due to weakening of the gravity field.'
    Captain Picard-
    'Transfer auxiliary power to gravity plates.
    Mr Worf; evacuate decks 7 through 19,
    Doctor Crusher; prepare to receive casualties.'
    Captain to Engineering; 'Mr La Forge; what's going on?'
    Lt Cmdr La Forge-
    'Captain, there's an unknown power drain on the warp generator, the field coils are overloading๐Ÿ˜ฎ, STAND BY'.
