My guess is that you are going to draw a blank on templates for the side panels, Ace, especially given that the boat is now 23 some years old.
If the panels are still installed my guess would be that there's still enough meat to them to get a decent trace. That, or perhaps using the vinyl itself as a template since it has already taken on the bends and contours. Would be an arduous task, of course, but not impossible.
