Hi Rick,
The Calvert spinnaker we used this year in the Steeplechase is not a 'Hooter'. It is a code zero spinnaker (software) plus alot of special Dave Calvert design spin and a little Bill Roberts design spin on sheeting angle. We used this sail for about 2 miles out of 55 miles on the first day of racing.
The SC20 DID NOT PITCHPOLE on the second day of this years Steeplechase Race. The boat did run aground and break the rudder off, then round up and turn over sideways slowly. We sailed the last 2/3rds of the race with one rudder and there were several times that the one remaining rudder was in the air leaving us to steer the boat at 20+ knots with the sails. It was a wild ride home!
Bill
