Sure you can. I was just wondering if it was the old 28' hull, it was like the Magnum 35 and Donzi 28, We also built a 29' hull, The same as the Magnum 27, Cigarette 28, Jean Claude had one as a race boat called the Beep Beep. It was trailerable, I designed the hull when I was 12 as the 19' cary, my dad yelled from his bedroom that he only wanted it to draw 6", so I had to erase the original hull vee and redraw it, however, Don saw it and Walt Walters drew up the 27' Magnum and what became the 32' Cary raceboat called the Cigarette. We used chrysler 330hp 440cid as standard on striaght drives, we also offered 427's either Holman&Moody or Daytona at about 500hp each. So you might want to reconsider getting some case engines, If it had outdrives then it was most likely a 29'. We used an insert to build the 26 sport boat. The 29 was like the 28 with side consoles and small cabin forward, the 26 was neat but it was just a cruiser with a cockpit. The original 28' was 9'10" wide, if it was a 29 it was about 8'. I'm not to familiar with what Jean Claude did but he also did a Chris Craft that was the same boat.
