Orion I just had a thought and a chuckle. If you think my project is daring you should read the post about the guy who cut his 35 Cigarette down and made a 28 open out of it .

Orion I surely hope you are wrong about the structural integrety. Phil at Lipship marine certainly didn't share your concern as he has done this modification on more than one occassion . Given the bonding materials today I am hoping that the structure will the same if not better . Hulls are repaired successfully on routine basis these days I hope mine falls into that category . Besides there is no turning back I already cut the hole.

Cafe Man don't give me any crazy ideas . Come to think of it I think I saw a 41 Apache for sale that had a step put in it. I never heard whether it actually worked . All kidding aside given the type of boating I do ( pleasure) I have never been a fan of step hull boats not withstanding the performance advantages . Even thought straight bottom hulls are slower I think they are just more predictably ( read easier ) to drive . Just my personal opinion.
I will post pictures of my adventure as it progresses .

Cored Hull or Solid? Make sure you grind back real good all around seam before starting layup, at least 8 or 10 inches.

Rick, I am the guy that is redoing the 35' Cig into a 28' cc. You have no reason to be concerned with structural integrity as long as you use the right materials and proper prep. These hulls are laid up with polyester and last for decades, so by using superior vinylester and epoxy resins with new fabrics you can improve the structural integrity. Do make sure to taper the bottom laminate back from the cut to maximize the bonding area. I applaud your project. Just got the teak floors installed in the 28. Hope it does not fall apart !

Automobili , it is a solid kelvar hull no coring ( thank god one less issue to work around). To clarify the hull is laid up in alternating layers of Kevlar weave and mat . The basicc hull I counted to be a total of 18 to 20 layers . the stringers areas and especially the keel are significantly thicker( more than double in the keel area) . I agree I had intended to fearther out at least 6 to 8 inchs on the outer hull and 8 to 10 inches on the inner hull in addition to tying the the center and next stringers throught the notch into the new transom I am doing . I am certain it will be plenty strong. The lay up will consist alternateing layers of biax and trix with kevlar for good measure , bonded with a particular vinylester resin.The finished uncored notch should be atleast 3/4 of inch thick at the thinest part. I'm goung for strenght not weight ( keep in mind it is only a 9 x 9 inch notch).
