I have a similar self-righting rig on my Hurricane. I have had this very discussion (could I start the boat etc post-capsize) with a couple of the local Coasties. They made the point that regardless of what was lost, or regardless of whether you can get underway or not, you are always going to be better off in an upright, swamped boat, than you are in the water, beside a flipped boat. Especially considering that our water is about 2C in April, and stays really cold until august before it starts cooling off again.
There are two big risks when using this sort of system: One is that the crew might get clobbered by the boat coming over, and secondly, when the boat starts to rise up before flipping, it will act like a sail (presumably it's howling out if you managed to flip the thing in the first place...) and unless the cres is tethered to the boat, it might very well drift away...
I'm happy to say that I have never had to use my self-righting gear!
