FLAT BOAT AND FRAMEWORK FOR SUPPORTING CANVAS A small collapsible canoe is disclosed which includes a canvas stretched over a knockdown frame formed from fiberreinforced plastic pipes each containing a synthetic fiber selected from a polyester fiber, a polyamide fiber, a polyethylene fiber, a vinylon fiber and an aramide fiber as a reinforcing fiber. Each of the pipes has a specific gravity of 1.5 or less, a bending modulus of elasticity of at least 40 ton/cm2, an IZOD impact strength of at least 80 kg?cm and a duPont impact strength of at least 0.2 kg x 500 mm.
