Do you mean California Performance known as CP hulls??
If you are asking about CP hulls I know they are a fast jet. Some of them are a very light layup that you can't even walk on the deck without breaking it and it shakes like a bowl of jello under way. They did make some heavier layup hulls. I heard they made a certan model that liked to make left turns and spit drivers out. Just a rumor, no details on that.
About 10 to 12 years ago a few friends I hung-out with had jet boats. Eliminator bubble, a Wright and a Miller all with built motors and a Eliminator scorpion with a 800Hp blower motor. One of the group purchased a old P.O.S. CP hull. He stuck a basily stock 454 with a RV cam and tunnel ram in it and smoked everyone, but the Eliminator with the blower motor, by a good 5+ MPH.
I wanted a CP or Daytona for a while but went with a Sanger Hydro instead
