We are fairly new to this boat, sailed out in 20 kts wind with 2+ ft waves today. At one point, the GPS was logging tops 12kts when we were blown over on our side. See @ 20 sec here http://www.youtube.com/watch?v=ivx_Um52N8k

Boat was filled like a tub and waves going over, bailing water was pointless. I had to jump in hold to the stern and tiller. My 13 year old was staying in holding the Jib, slowly pulling us to shore.

I was surprised about how filled the boat was, practically unrecoverable in those conditions.

Comments?

Thanks. Siggi
