    Environmentally sound, but too big a job..
    Nope, tyres are very unsound indeed. Full of toxins that gradually leach out into the water. Artificial tyre reefs were found to be a bad thing a very long time ago.

    Hold the fender underwater with the filling needle in place to keep the valve open - some jiggling and sqeezing will get nearly all the air out.

    As far from the sea as we could be, except when we can actually get in it.

    What about "keelhauling", with a couple of fenders (joined by a short rope) in the middle of the hauling ropes. Pass the rope under the bow, pull the fenders under, draw them back to where you want them and secure either side.

    AFAIK, keelhauled sailors were generally a bit buoyant, they just didn't do so well if the guys above stopped pulling.

    Thanks, I'll try this next. Been squeezing the things on dry land and rolling them but only water comes out. And they weigh 14kg each so not easy to manoeuvre. It will be easier in the bath I weighed each of them to see which ones had most water - and therefore least air.

    Yes, that's exactly what I'm planning to do. From the front of a rib it's a bit difficult leaning down that far and pushing them under, hence my need to get them a bit less buoyant.

    Fastening some bricks (the ones with three holes through the middle) to the underside using large cable ties could be enough to provide just enough negative buoyancy.

    Or, a brick(or two) in the middle, on the rope between the two fenders?

    If you think that's a hassle, have a look on the web for Pip Hare changing a rudder mid-ocean, during the Vendee Globe. Effing brilliant.
