    Having a fifth language way outdoes a bit of boaty terminology :)

    I have plenty of room under the bed in the cabin for the tank/bladder. Can take water from the raw water intake and pump it out using the side exit used by the secondary manual bilge pump that is on the port side. Must check with the suppliers of this gadgets. Not sure how the pump operates and if it can suck from one place and pump to another. would need a way to switch over, a relay perhaps? What about pump out through the raw water intake?
    This mob seems to have all I need, but they are scant on install details.

    You don't drain via a rwi for the engine.

    You can check out flow-rite.com.

    Much depends on the ballast tank bottom being above the waterline.

    Not true. Its ballast in any position.

    Of course it is, but the post is out of context as quoted. I was referrng to draining the tank. When he said under a bed; I wondered the tank bottom height. A bed might be rather low in the hull see.

    If too low, you'd need a pump out.

    It doesn't matter the height of the intake, but the height of the waterline; so draining through the intake is impractical.

    That makes sense. I read it as a one liner.

    But let's face it, any tank that isn't going to be a good foot above the waterline, cannot be relied on to drain by gravity. Differences in boat loading, wave conditions etc are all going to make the pumping option mandatory.

    The OP's problem is the boat pulling to one side. This has been solved for many decades with a small trim tab in the rudder.

    We also have another question from the OP. You might like to go back and get acquainted.
