Cardboard boat racing is a construction competition that has been used to get students interested in STEM fields. Competitors have to build a boat using only corrugated cardboard, and sometimes other materials such as glue, sheets, duct tape, and paint. Once the boats are built, they race against each other in a shallow pond, swimming pool, or river. The boats will almost always flood, sink, or shred under the weight, due to the difficulties of waterproofing cardboard.
| Characteristics | Values |
|---|---|
| Materials | Corrugated cardboard, glue, sheets, duct tape, paint, latex paint, personal flotation devices |
| Rules | No wood, metal, plastic, foam, or fibreglass. No wax-coated or pre-treated cardboard. No wrapping the entire craft in duct tape. |
| Boat size | Larger boats are faster but harder to turn. Smaller boats are more agile but hold fewer rowers. |
| Competition type | Construction competition, with races at the end. |
| Audience | Elementary-school students, college students, adults. |

Cardboard boat racing is a popular construction competition for people of all ages
In a typical competition, competitors have to construct a boat under a fixed time limit using only corrugated cardboard, glue, sheets, duct tape, and/or paint, although materials vary by competition. Some competitions are even more limiting, such as the New Richmond Annual Cardboard Boat Regatta, which only allows paint for waterproofing and duct tape for construction, explicitly banning the use of glue or sheets. Once teams have finished their boats, they race against one another, usually in a shallow pond, swimming pool, or river. The boats will almost always flood, sink, or shred under the weight, mostly due to the difficulties of waterproofing cardboard. In Rainy River, Ontario, races are held in two divisions each year with simple rules: Purist Classes, where team registration includes a supply of all materials used for boat construction.
There are many things to consider when constructing a cardboard boat. For example, larger boats are faster for straight-aways, but are a beast to have to turn around corners. Smaller boats are more agile, but will hold fewer rowers. Another thing to consider is the total weight of the craft and crew. All members of the boat are required to wear personal flotation devices.

Cardboard boat racing can be a fun and engaging way for students to learn about engineering and design. Students can approach the challenge with "hands-on" learning, applying their knowledge of science, technology, engineering, and mathematics to build a boat that can float and race. They can experiment with different materials and construction techniques to see what works best. For example, larger boats are faster for straight-aways, but are more difficult to turn around corners. Smaller boats are more agile, but will hold fewer rowers. Students can also consider the total weight of their craft and crew to optimise their design.

Cardboard boat racing competitions vary in terms of materials allowed
Cardboard boat racing competitions vary in terms of the materials allowed. Some are more limiting than others, with some only allowing paint for waterproofing and duct tape for construction, banning the use of glue or sheets. Others allow corrugated cardboard, glue, sheets, duct tape and paint.
Some competitions also have rules about the type of cardboard that can be used, with some prohibiting wax-coated or pre-treated cardboard, and only allowing bare, raw, brown, fibrous cardboard.
The type of waterproofing used is also important, as some sealants will soak into the cardboard and make it very wet and weak.
The size of the boat is another consideration, as larger boats are faster but smaller boats are more agile. The weight of the boat and crew is also a factor, as the boats will almost always flood, sink or shred under the weight.

Cardboard boat racing competitions vary in terms of the number of passengers allowed
The rules for cardboard boat races vary by competition. In some races, only corrugated cardboard, glue, sheets, duct tape, and paint are allowed as construction materials. Other races may ban the use of certain materials, such as glue or sheets. The "International Cardboard Boat Regatta" in New Richmond, Ohio, for example, only allows paint for waterproofing and duct tape for construction.
Cardboard boat racing is a popular construction competition for people of all ages. The races are often held in shallow ponds, swimming pools, or rivers. The boats usually flood, sink, or shred under the weight due to the difficulties of waterproofing cardboard. All members of the boat are required to wear personal flotation devices.
The earliest documented cardboard boat race was created by Richard Archer at Southern Illinois University in 1974. Since then, cardboard boat racing has become a way to get students interested in STEM fields by approaching engineering challenges with "hands-on" learning.

Cardboard boat racing competitions vary in terms of the size of the boat
Some races are held in two divisions: Purist Classes, where team registration includes a supply of all materials used for boat construction, and another division where teams can bring their own materials.
The size of the boat will also depend on the theme of the competition. For example, a pirate ship or banana-themed boat is likely to be larger and carry more passengers than a dragon-themed boat.
The number of rowers and passengers will also affect the size of the boat. A larger boat will be faster in a straight line but harder to turn, while a smaller boat will be more agile but hold fewer people. The total weight of the craft and crew is an important consideration, as this will affect the boat's speed and manoeuvrability.

Frequently asked questions
Cardboard boats are made from corrugated cardboard, and can be waterproofed with paint. Some competitions allow the use of duct tape, glue, sheets and other adhesives, while others are more limiting and only allow paint for waterproofing and duct tape for construction.
This depends on the size of the boat and the weight of the passengers. Larger boats are faster but harder to turn, while smaller boats are more agile but hold fewer rowers. All members of the boat are required to wear personal flotation devices.
Cardboard boat races are usually held in shallow ponds, swimming pools or rivers.
