Huh...I don't know of a Mark in OK? Or his CVZ project. I knew of Mark Turner's CVZ project, but his seats were a dark green, and didn't have a bow cover at the time. Is that the Mark you're speaking of?
Honestly, I think if a guy takes his time, a cover could be made, there are some bends etc, but nothing that I would consider a show stopper.
Do you have any more info than that Rich? A guy with a boat that nice would be part of the club, especially if he's in MN...but I've never heard of one up there. AFAIK...I'm the closest (to MN) CVZ-18 owner in the club.
