Works great as long as you have stringers so the sheathing has flutes that run longitudinally.
Or, make the hoops longitudinal. Use Dacron instead of canvas, comes in lots of colors, heat-shrinkable with an iron or heat gun, to custom fit. A gagillion ultralight airplanes can't be wrong.
Lightweight app. for this can be shamelessly borrowed from kayak designs, such as George Dyson's baidarkas. Google for that. Geodesic canoes and kayaks, too.
Also, foam sculpts easily, add fiberglass for sandwich structure that is also good and light.
