25 seafari conversion to CC

Outboard plus CC conversion will, for certain, create huge cg problems in that hull(I owned one). You will need a LOT of weight forward, pig iron, fuel tanks, batteries, fish boxes that will have to be kept full, whatever. Study up on cg and do the best calculation you can.

Yes!!! There's a reason Potter never produced a 25' CC. He told me one day " We just couldn't get it right"
You better think this conversion idea thoroughly..

My understanding is that the reason it didn’t behave right is that Moesly intended for it to be built with the ballast system he had designed (and patented!).

But Potter never built it with the ballast system! The comments regarding the 25’s sensitivity to CG location and trim tab use imply that a ballast system might very well have helped alleviate some of the reported handling problems. And the additional bulkheads required for ballast tanks might have also provided additional stiffness to the the hull!

Perhaps adding some rubber bladder tanks under the deck which can be filled and drained without the use of vents would allow you to adjust the CG location on this hull while underway like Carl Moesly intended!
