Will there be some difference in strength of the strip built kayak versus the plywood kayak, if the thickness remains the same as the plywood kayak?
The "wood" material is not as critical in kayak building as you would think. It really is providing a spacer between the two fiberglass skins, much like the horizontal web of a steel "I" beam. My first kayak was a plywood, stitch and glue, from 1/8" lauan ply. I didn't trust the thickness, so I
way overbuilt it. It could weigh about 15 lbs lighter, and be just as indestructible. The strength of the boat is in the type and weave of the cloth, and the resin. The wood fills in the gaps, and makes it look pretty.
The expedition sport is a good design, and Jay Babina's "Outer Islander" is awesome for a sea kayak. Check out some of Nick Schade's designs. I've built three, and may build a fourth next winter.
