Yes gotta have a windshield. Also would need to sit in one and get a feel for driver ergonomics. Tilt helm(hopefully), throttle position etc. Would prefer a rear facing observer seat that you could lift to get to storage. In the J it looks to be just all open under there for stuff to come back and whack your toes. Could move that rear seat forward a bit and create an upholstered sunpad over a storage compartment at the rear. That rear gel corner is gonna be exposed to dock tie ups etc cuz the rub-rail is narrower than the gel. Looks cool but the rail isn't protecting anything back there.
My old Centurion Falcon Barefoot that I posted about above had none of those issues. Great enclosed bow storage behind the rear facing observers seat, a real tourney boat windshield and ski mirror, tilt helm, nice ergonomics from seat to throttle and wheel. Rear u-shaped seat also had storage behind it. Rub rail was useful protection front to rear. The Flightcraft's and Sangers were great, too. Swim platforms and rope guide over motor. Center mount pylon with fins underneath. I think over 20 years later it could be done better than these J's which remind me more of Switzers, Checkmates, Hydrostreams.
Ron just find yourself a used and pristine Malibu-Flightcraft Outboard--no wood, great build, better ski/driving and barefoot boat than this new J--and probably lots cheaper.
