Last saturday. I was helming on a friends boat (Nacra F18).
He just got it and after spending a couple hours setting it up we wanted to take it for a inaugural sail,
of course we had to set the spin and with the 15-20kts and the ultra steep lake waves it wasn't long before digged both hulls in and he peter-panned to the forestay.
Both water and air temperature where about 7c celsius so we got it back up in record time <img src="http://www.catsailor.com/forums/images/graemlins/wink.gif" alt="" />
One tip to prevent turteling is to slide out the daggerboard and lean against it until someone gets a hold of the righting cord.
