I've had second big 'off' in a month while gybing - both at the same large lake sailing location in waist deep water, with (occasionally very evil) steeply stacked close-period freshwater chop/lake swell, up to ~50-80cm in size.
The first crash temporarily dislocated my jaw when the nose of the board submarined into some steep chop at high speed during a very committed very powered up gybe resulting in a catapult that gave me concussion for two weeks, and I fear yesterday evening's crash, when the board went total yard-sale as it launched off chop mid-gybe very powered up at high speed, may now have resulted in a broken foot (waiting on x-ray!).
Clearly I must be doing something wrong - relative to the conditions.
I've done 1000s of successful gybes at this particular location, but in the last few months I've been working on a semi-laydown style gybe - straight front arm, sheet in, 'see' the nose of the board, carve, foot change, rig flip, exit. This kind of gybe is brilliant at maintaining mast foot pressure and driving the board through this nasty chop and maintaining speed BUT I suspect the power factor combined with the conditions, means that when it does go wrong, it goes massively wrong with a big bang. I actually thought the problem with the first crash was that I wasn't committing to the gybe enough, but I think I've nixed that idea now.
Previously I used a more 'open sail' gybe technique here, keeping the rig in front of me and bouncing over the evil chop, but was told sheeting in and laying it down was better

It certainly looks cooler, haha...
Any tips or advice, or should I just lay off the committed semi-laydowns at this particular location. Boards are Tabou Rocket Plus 113 with GA Cosmic 8.3 in ~16-18 kts wind (foot damage) and Tabou 3s 107 with GA Hybrid 6.4 in ~22-25 kts wind (concussion).
