They have a density that is lower than water.  Some teams simply
create large voids in the canoe ends for this purpose, but most make
the concrete composition less dense than water.

If I understand correctly, one of the competition events includes
completely submerging the canoe near a checkpoint and then bailing it
out before continuing the race.

So it's just like a regular canoe... Only not.

My brother in law helped out a team one year when he was getting his
civil engineering degree, and he made a concrete rose for his wife
which floats in water.  It feels like concrete - but extraordinarily
light.
