Often when a person first hears the words "Concrete" and "Canoe" in the same sentence skepticism tends to arise.  If you would like to fulfill your curiosity with answers then feel free to look though the photos on this page and your then welcome to attend one of our meetings.  I'm sure you would just like to know how concrete can possible float.  Well the answer to that is both in the shape of canoe and what goes into the concrete mix.  Even if a material is more dense then water the shape of an object can give it the surface area need to have enough buoyant forces to keep it afloat.  At the annual competition a swamp test is required of each canoe.  A swamp test requires that the canoe be completely sunk by filling up the haul with water then forcing it under water.  The canoe must then be able to resurface by its on buoyancy.  This requires that the boat actually be less dense then water.  They are a couple ways of achieving this feat.  The Drexel uses a combination of light weight aggregate and cast in place Styrofoam floatation tanks located at the bow and stern.
