About Concrete Canoe

Mix Design

Three different mix designs are created, tested, and analyized for the canoe design. Once the results are compaired, the prevailing design will be chosen.

Hull Design/Structural Analysis

During the design phase, three different models for the body of the canoe are created. The goal is to have a manueverable, but nimble design. The structural analysis ensures the canoe can withstand the forces applied without failure.


Constructing the canoe allows for all design aspects to be implemented. The sytrofoam mold will be built and shaped appropriately for the concrete to take shape of the canoe.


The canoe will compete with other universities. The design process, canoe prototype, display, and rowing competition will be judged. The goal is to have the best canoe!
