Well the rig thing: The mast could be secured by a UJ as in windsurfing, so the base wouldn't come adrift if a halyard were slackened to let the mast fall one way or the other. It would also assist an auto rake system, I'm sure some sort of pulley arrangement could be worked out to re hoist it once upright, not sure if I'm ready for this one yet, but it's definitely a consideration.

I'd thought more about the wing buoyancy, if it were over and one could be released, then the other remaining in place might tilt it sufficiently to get an angle on the centreboard to get some weight on.

I am wondering about cutting the side tanks about, especially if it could be done in a way I get to chuck out some weight, it's a foam sandwich construction, which in itself floats without tanks, it would probably be pricey and if i were to go for cutting it about there are some other things i'd also change.

But before all that it needs a few more goes as it is, with at least one go with all the rig controls working the way they should, just to see how it does go, to satisfy the atrocities of this world and of course my own pleasure, no point slogging along at the speed of a vision just for the ease of the ride, although i must say it was a whole lot faster than had i been in a Blaze or an RS100 and a darn sight easier. I didn't actually get to swap tacks with anyone, I'd started late and gone the wrong way, the buoy they'd laid whilst i was out messing about had drifted and the course had become a typical Hythe very short Fetch, fetch, run, Contender Course, they love their fetches and tight reaches.
Whilst i was hooning about while they readied for the race it seemed better than on the pace to most i came alongside, it pointed as high as the merlin, and the Phantom, overtook a laser, that's about all i recall, i can't say paying attention to anyone else other than not smashing into them was much on my mind, it's quite a white knuckle ride.

What about a system that you can hoist to the top of the mast when inverted. I.e. a series of floats that would be fitted to the base of the mast or hull whilst sailing and then hoisted via halyard to the top of the mast to provide buoyancy.  Once the boat is upright these can be released back down.  It sounds a lot like science fiction, but this discussion seems to be talking new/experimental concepts to an age old problem.....the seemingly dreaded turtle.

Was thinking of a foam sausage perhaps which could be stored in the racks and then hoisted when required.  Would also make the racks buoyant as a plus.

There's as much chance of me sailing with a 'sausage up the mast' as any of you becoming windsurfing world champion in the near future. I'd sooner drift out to sea, never to be seen or heard of again.

But that exploding sausage device, how does that work then? Inflates on contact? Not when it gets wet I hope, how is it triggered? Pressure? Motion sensor?

Edit: 

Right, that's sorted for now, then, just hope it's enough to stop it going right over and I'll take my chance if I have to swim for it, the more unlikely scenario imv.
I shall still inflate the wings and teflon balls in the the mast sounds like a good call as well.

i think inflated wings will only help slow down capsizing, but once your over will make it harder to get up!

edit: also that exploding sausage requires re arming every time you capsize, just saying

The whole point of the gas filled mast float thingy is that there is no reason why it should notice when deflated. I might be old, bald and past it but even I resist the idea of a pop bottle tied to the mast head. Remember, my idea was to connect a deck mounted gas cylinder that had a valve operated by a string through the center board slot.....hey use helium and a big enough mast head bag and it could shoot up with the mast vertical throwing the noble Mr Fuller off into the oggin!

The idea of trying to sink a float down through the water using rope and pullies sounds like a non starter to me.

Would it be possible to use some sort of lever to right the boat?
Maybe it could be carried under the rack somehow?
Use it like putting your weight on the plate, but longer and at a better angle?

For the lever to work well, you still need a way of exerting pressure in the right place. I know that if you have a lever big enough you can move the world, but the Vtwin might be trickier than that...
