I'm not sure, it was easy enough to carry by just myself, so the fiberglass weight wasn't significant.
According to this chart: http://www.boatdesign.net/forums/attachments/fiberglass-comp...
The fiberglass weight would be under 3lbs.
For the plywood - 3 pounds per square foot per inch of thickness according to APA Plywood Design Specification so
= .25 thickness * 8 width * 4 height * 3 lbs
= 32/4 * 3
= 8 * 3
= 24lbs plywood weight
So I'd say the boat was between 25-30lbs and that feels about right.
That's quite light, considering my cannondale mtn bike is ~25-30 lbs.
Still, I'd love to see what additions such as AeroGel powders and carbon nanotube fibers would do to the weight of a rigid boat such as a canoe.
