Has anyone every tried or considered using solid fiberglass rods as stringers for a SOF build? Certainly not light, but they seem practical for larger pulling or sailing boats where extra weight could be neutral or even a benefit. 3/8in x 8ft fiberglass tree stakes can be mail delivered for under $2.50 each, with 2 joined by 6-12in brass ferlues (sp?) for a 16ft stringer for under $6 and less than 2.5lbs. I'm currently in build on a slightly modified 15ft SOF Rangeley with a flat timber bottom (16in midship) with probably 6 fiberglass stringers per side. With a stout ballistic nylon cover and white pigmented Zar poly coating I am expecting a classic planked profile.
