Hi dennis, something tells me this may not quite fit a strippers sophistication,but here goes: Would clc's 15.5 Mill creek work? , but with a closed deck. the hull shape is a little like a wide prijon yukon tour,ie.5 panels. If your friend has sat in any production kayak he has some sense as to what is workable as far as beam and cockpit size. Necky has a glass boat called a Pinta that is huge and perfect for a 300lb paddler. I figure it would make sense to design a boat coming from your friends experience from being in a boat.
