Back in 1979, students in the Civil Engineering Technology program decided to undertake a big challenge. Using advanced state-of-the-art concrete technology, they decided to see if they could build a canoe out of concrete that would float. According to a press release dated August 20, 1979, the students planned on launching the 500 pound, 17 foot concrete canoe at Cincinnati’s Public Landing on August 23, 1979 at 9am. Students in the plastics technology program provided the construction mold and even built the same canoe from a plastic compound, which was launched in the College’s swimming pool.
Unfortunately, I couldn’t find any information in the Archives about whether the launch was successful. However, according to one previous employee, at some point a concrete canoe sunk in the college pool. Maybe some old timer’s out there have more information they could share about that?
According to another press release dated August 21, 1981, just 2 years later, both the plastics technology students and the civil engineering students were at it again. They decided not only to build a boat with the same design, but also to race it in the Burnet Woods lake. The plastics boat weighed some 60 pounds while the civil engineering boat (made from concrete) weighed 200 pounds. To even out the weight difference, the concrete boat required 2 sailors while the plastic dinghy had to use 3. No word on who won this contest. Again, maybe an old timer has some information.
In more recent years, students in the local chapter of the American Society of Civil Engineers (ASCE) have competed annually in a competition to build a concrete canoe since at least 2004. In 2006, the college even hosted the Ohio Valley Regional Conference of the ASCE which took place in Lawrenceburg, Indiana and on campus at Cincinnati State.
Just this past Spring, students competed yet again. According to Cincinnati State ASCE members, Bryson and Brodbeck, the canoe not only floated during the competition, it held weight pretty well – and didn’t capsize until the fourth student climbed on board.
