Anyone got one?
How much more expensive are inversion proofed engines than normal?
I donít recall anyone here who has one for purely leisure use. Itís an extra bit of kit to maintain (bag to inspect/repair, gas cylinder to look after, system to inspect/test). It also has to be on an aframe strong enough to cope with the forces involved and as you rightly point out minimal value without post immersion restart engines.
The conditions necessary to flip a rib big enough to need a bag mean any sane leisure user has gone home, or is cautiously trying to get home - not blasting through waves. I donít like to rely on the lifeboat but if I ever do capsize a rib my first priority would be calling for help not getting it back up - the chances of doing it in a location where you donít get blown onto shore/rocks before you get a chance, here nobody is injured, where you actually get the engine etc back running and are able to limp home proud not to have put out a mayday are pretty small. They may make sense if you operate somewhere where help is far away (or you are the help).
As far as I recall no leisure user here has capsized a rib whilst driving it in a sensible manner.
