Not the same boat - the video cat has no forebeam and has a bridgdeck of sorts. The Tennant is a 3 beamed boat with no bridgdeck. Malcolm's foredecks would never have had the lip on the inside - he loved arcs and the foredecks were usually cambered heavily. Good for power reaching.
We have a Bladerunner on the lake here (sistership to Afterburner) sailed on her quite a bit. Used to bend and break small things often - lots of power. She doesn't sail much now but is still in good nick. The owners are more into bushwalking than sailing now.
cheers
