Pete, I don't know of any "real world videos" of AI/TI capsizes and righting. Anyone who has sailed a cat, such as the Hobie 14 or 16, is very familiar with the steps in righting this type of boat--there may be videos for righting these boats. In my case, I capsized my 2015 AI loaded for a 4-day camping trip in winds of 17-18 mph, gusting to 21 mph. I, like you, broke an aka brace pin in open water with insta-capsize. You can read about it here:
http://www.hobiecat.com/forums/viewtopic.php?f=70&t=54465 I have experience, many years ago, on a Hobie 16 and righted it many times. I thought the righting of my AI 2 was "routine," and it was definitely "real world."
That's where I am coming from: two 16's, 3 14's, and an outrigger canoe - both in Hawaii and East Coast USA.
I'm basically taking the Hobie14 approach (one man's body weight....no bag full of water slung over my shoulder as with the 16's) with pre-capsize aka-folding mitigation added and intentional folding of one set of akas during the recovery process (in the event that one isn't already folded).
Seems like no problem in bay water (i.e. the mast stuck in the mud and the boat on it's side instead of turtled). .... not as easy as an outrigger canoe, but easier than a 14 or 16.
I did try one test with mast removed to allow the hulls to turtle; and it worked.
But I have no venue to test my system against a real-life full turtle situation and I was fishing for some vids/experience that might point out some flaw in my reasoning.
One diff from the 14/16 scenarios is that. with the 14's and 16's turtled, you can easily climb/swim up on to the tramp, stand up, get positioned, and then step back on to the inverted hulls and lean back against the righting line.
I don't expect to be able to climb up on to the inverted AI hull, stand up, and do that..... but did manage to get it to rotate sans mast from full turtle by bracing my feet against the side of the hull, bending forward at the waist, and pulling on the righting line until the hull started to rotate. ..... Of course once there was sufficient rotation to give the righting line some leverage, my weight easily pulled it right up and over.
Next time I get motivated to do some tests, I plan to see if I can heave my butt up on to the turtled hull and then try leaning back against the righting line from a sitting position - or maybe, using the righting line as a brace, transition into a squat and then stand up.
Another thing I want to try is a righting pole: something you can lay across the inverted hull, anchor against the extended ama or one of the akas, and then hang your body weight on from the water to get the boat partially rotated to the point where you have enough leverage via the righting line. ..... And the length of such a pole could be reduced by folding the other ama too..........
OR, now that I am actually thinking this through, maybe a righting pole that sticks into one of the scupper holes that take the beach wheels..... now you have maybe 3' or more of lever arm sticking straight up an
maybe you can grab that from the water far enough up to get the leverage to initiate hull rotation.
I suspect that one joker in the deck may be twisting damage to the knuckles of the folded akas - either by inadvertantly bracing against the accidentally-folded ama or by the leverage of said righting pole on the intentionally-folded ama...... which leads me to think even more favorably about the scupper-pole approach.
