RE: Lengthened Ocean Alexander MK1 handling characteristics?

I have always heard the standard rule of thumb on extensions is you can lengthen up to 15% and get away without moving rudder, etc. You would fall far below that so I would imagine no problem. I think they were lengthened to copy the huge aft deck on the Flemings, you would also get more speed, load capacity, storage, better ride in head seas and improved fuel efficiency. The rudders on the OA are tad on the small side to me so I don't know if tracking would improve or not.
