After our pitchpole experience at Spring Fever, I felt we did 2 things wrong. Crew weight was too far forward (crew was still on trip and mid way on hull) and I didn't ease the mainsheet. We had overstated the mark, so we were already traveled way out and reaching down to the mark. As soon as I beared away at the mark, it buried instantly with no recovery possible. Since my traveler was out I didn't think I needed to depower the main anymore, but I think easing the mainsheet would help twist and spill off the main.
Since then, I've traveled out half way and ease the mainsheet as needed. If it digs, I can dump it all. Once I make the turn, I then sheet back in as the crew is hoisting the spin.
