A few more tips:

• A flat bottom is recommended. A V-shaped bottom is likely to tip over unless the V is very gentle.
• The lowest center of gravity is the most stable; standing will cause you to tip over.
• Maximum dimensions are 80 cm x 200 cm (strictly enforced)
• For height, allow about 18 inches for you to sit and paddle effectively without the edge of your boat blocking your arms.
• Only 4 materials are allowed: corrugated cardboard, masking tape, latex caulking, and latex paint.
• Measure twice and cut once.
• Fold a lot and cut sparingly.
