Fishhead, I bought the molds to Aero / Predator boat company some years back and one of the pieces of tooling was a modified shadow,except the chines are a little wider it has been streched at the transom with a notch and 5" more free board at the transom. The first one I built was in 1998, I rigged it with 300 Pro max's / 1:62 gears/ 32 x 15.25 3 blade clevers the boat weighed 4119 lbs dry the boat ran 109 to 111 pretty consistantly. We are going to cut a new hull down the center of the tunnel and widen it 12" and put a 1.6" spray rail / body line in the freeboard side to give it some new look. I have not decided which way to go with the deck yet, but I am going to do a one off deck with a canopy for next years race season. Check out my website you can see how we build the hull now, No more hand laid glass everything is vacuum infused its a great process.
Talk to ya later.
