I built this little screamer with a local youth
over last summer. The hull itself, minus rig, centerboard
and rudder weighs about 60 lbs and the boat vibrates like
a drum when you tap it. It is reverse-sheered with an extremely
powerful midsection. It is meant to be over-rigged and somewhat
terrifying to sail - the client is a teenaged boy after all.

It has a 16 foot spar, and 10 lbs of lead in the CB alone.
Hope to get her on the water in a month or so....
