Your explanation should mention forces on the water and forces on the paddle.

conservation of momentum and work done by the man tha padles is the answer. actually while paddling you push the water backwards. like the airoplane's turbines that push the air backwards..the net effect is to move forward in order to have a system that the momentum is conserved.

basically, water is near as damn it a solid object-it doesn't actually move. kayak and canoe blades are so thin that they slice into the water, and as the paddler pulls on the blade, it creats momentum. try it next time you have a pat of butter open in front of you-stick a knife in it and pull the knife toward you. the butter will move.
now imagine that as a kayak/canoe on a lake. QED!
