Cardboard Boat Design Suggestions
• Set the Design Goal: Fun, Speed, agility and Appearance
• Sketch out your design
• estimate materials or plan how to use what you have
• plan out what construction techniques will be used
• 1’x1’x3’ box: will float 187 lbs.
if it’ll hold you, it’s big enough to float
• Flat bottom, sit-to-paddle & canoe styles - are the best/easiest
• Rudders help keep you straight but make turning difficult and
adds complexity to your design.
• Long boats go fastbut are harder to turn• Short boats (<8’) - are difficult to keep straight
• Best Length: 8-12 feet
• Best Height: 18 inches
allows room to sit/kneel & still paddle over the edge
• Best Width:
18”- 30”(max) for 1 person
48” wide for 2 people side by side
• Kneeling is a “power” position but sitting is more comfortable
• Cover all edges of cardboard - acts like siphon
• Cardboard Tubes make great frames
Cut for joining & bendingFasten tubes together
• Cardboard Hull
1-2 layers, fasten & cover the seams
• Reinforce the area where you sit, kneel or stand
