Flipping a RIB, for all but small RIBs or those with self righting I belive is a ONE WAY TRIP
I know if I flipped my RIB their is NO WAY i would right it, however many people we had on board.
Working on this I decide to plan to make the best of things, and just a few thoughts that you may want to consider.
1) Its going to happen fast
2) your going in with what your wearing, no time to add extra waterproofs etc
3) your nice VHF is useless with the aerial etc underwater, even if it would still work, and the mic can reach the surface.
so what else can you get help with or help you survive
flares, can you get into the locker they are on a upturned RIB ?.
If they are in a tub can you open them or overcome the buoyancy needed to get them under the water andout from under the hull.
EPIRB, can you get at that, most dont float free and wont set of in their holder.
Spare VHF, can you get at it, why not always carry in in your pocket.
Ropes, nice to always put away but how easy is it to stop on a upturned deep V without something to hold onto.
Drysuit, could buy you many extra hours in or out of the water.
Could you still deploy the anchor is needed?.
Lots if things, hope if never happens, but it if does will all your plans that people put in place for emergencys still work ?.
Saying that we never go out in any conditions that would ever turn a RIB over
