I've pitchpoled my G-Cat 5.7M once. We were cruising south on the Gulf side of Egmont Key on a broad reach. I looked back and saw a gust coming and warned my crew. When it hit I turned straight downwind but the crew couldn't get the jib to uncleat. It was a hell of a gust- biggest of the day. The boat went VERTICLE! Completely stopped in half it's length and submerged to the mast beam. Catapulted my crew (who never puts his feet under the hiking straps) a good distance ahead of the boat. I had my feet under the straps and grabbed ahold of a foot loop behind me and stayed put. Once up in the air, I pulled my feet out and slid feet-first down the tramp into the mast, and rolled into the sail. The boat settled over on it's side as my crew came swimming back. We righted it quickly and had a good trip back.
Nothing puts the brakes on faster than a front trampoline!
