At the helm on a 67' steel hulled cutter rounding the "Horn", with storm force winds gusting hurricane force, we were taking most of the winds off the port quarter. A large rogue wave from the beam hit us pushing us over with mast hitting the water. Myself and the two cockpit crew were both clicked on and the crew slid aft to the transom without going over. Being on the wheel I felt the pressure of the very cold water wanting to cuase me to lose grip on the wheel force me over. While I was able to hold on there came another problem, that of not being able to breath. Fortunately the boat righted before I had to make the decision to let go and try for the surface.
Because the boat was prepared for this possible situation there was no significant damage nor injury. Although the experience was incredible it is onr that I would not want to do again. The preparation is the key.
