They came from around the world, students of civil engineering, to Evergreen Lake in the Colorado Rockies to compete with the best of the best in a race with canoes…made of cement.

“They have to find a way to make a concrete that [is] a) either lighter than water or b) that with the shape of their canoe can offset the amount that they are perhaps a little bit heavier than water.”

Building a concrete canoe that floats is one thing.

“They also have to innovate to insure that it’s a lightweight concrete that can float as well as one that, as they develop it, it can steer.”

The student competitors are judged on oral presentation, display, their final product and, of course, the race itself.

Design and weight of the canoes varied.

“We had a canoe here, it’s about 20-feet long, weighs 125 pounds, I think it’s the lightest. The heaviest is 370, close to 400.”

It was a lot more than just fun in the sun for the soon-to-be civil engineers. Prestige comes with winning this race.

“A couple of bags of Doritos and some Mountain Dew went into the training for this race.”
