we had a spectecular pitchpole with our Nacra F20C last friday, runing with the spi in ~17knots wind and ~0.8m waves.
The helm was sitting near the back beam and the crew was out on the trapeze with the chiken line, behind the helm, but it was not enough to avoid losing control and capsizing.
What are the reasons for pitchpolling and what are the best ways to avoid it?
