So yes, carbon fiber is legendarily strong, but that's only half the equation. It's also crazy light. The Delta 88, at 84 feet 11 inches length overall, displaces a scant 90,000 pounds. Carbon Craft, the builder of carbon-fiber tenders, has an 11-foot-6-inch model that weighs 900 pounds. Nine hundred. You and your friend could pick that thing up off the ground, assuming you haven't been skipping leg day at the gym.
