It's useful data. Little glass isn't as strong as more glass. Glass on one side isn't as strong as glass on both sides. Little glass doesn't resist abrasion/impacts as much as more glass at the point of impact.
Most of the wear a kayak gets is from point abrasion at the stern and the various edges of the bow/stern/coaming/hatches/sheer. Once you break through that glass the wood gets stained.
Care of use beats overbuilding any day. A carefully paddled 40lb kayak will outlast a heavily used 50lb kayak.
If in doubt build test panels and go at them,,or use your kayak a lot for all uses(especially rescure practice) and see what happens. Most likely on the next kayak you'll start applying extra light glass/epoxy on all those edges and glass panels on BOTH sides where impacts occur.
Building for the kinds of use that 60lb British glass boats were built for (t-rescues in 4' waves, surf landings) will most likely result in a 50-55lb s&g kayak.
