Just for the record i'm not trying to turn a seacraft into a conch.
I'm trying to turn a seacraft into a seacraft more suited to my style of fishing. I would not cut any shearline. The hull would remain the same. Liner removed, stringers raised 2-3 inches, floor glassed to stringers, hull sides cored, floatation twin engine bracket. My power would most likely be 115 4 strokes or 130 - 135 DI 2 strokes (optis or etecs). I would only raise the floor enough to ensure self bailing.
Once i find the right hull for the right price i will make this happen and report my findings. Hopefully it wont be all negative
