Sink or swim- that’s the question every cardboard boat captain must face on race day. After all, a cardboard box isn’t usually the first material to come to mind when designing a seaworthy vessel. Preferred material or not, the popularity of cardboard boats, also called cardboard regatta, races continues to grow each year.
Although its exact origins are up for debate, most believe the cardboard boat originated in1962 at Southern Illinois University. Professor Davis Pratt, in an assignment aimed at testing his students' creativity in design, asked the seniors to design and build human-sized boats made only of corrugated cardboard. More than 45 years later, cardboard boat races are going stronger than ever. There’s even a book on how to build a cardboard boat. The Cardboard Boat Book: How to Build an Environmentally Friendly Boat with Recyclable Resources, by Dave Friant, provides step-by-step instruction on how to build a kayak style boat with corrugated cardboard. The boats do not have to be made kayak style as outlined in the book. From pirate ships to riverboats and airplanes to animals, boats can and have been designed in any fashion that will float, so long as they are made of corrugated cardboard. Boats should be capable of completing at least three trips around a 200-yard course, to meet the challenge of The Great Cardboard Boat Regatta races.
But Can it be Recycled?
We’re always advocates of reusing materials to make new creations, and cardboard boat races definitely fit the bill. That being said, it is necessary to check your local recycling program rules as most recyclers will not accept wet cardboard for recycling. There are various reasons recyclers may not accept wet cardboard, from the extra water weight skewing the cost of purchasing the material to the potential of jamming the recycling sorting machines. Let the cardboard dry before placing it in a recycle bin. Paint and other decorative additions to the cardboard boats should also be considered, as those will usually render the cardboard non-recyclable.
