: I'm thinking that if viscosity and density increase as temp drops, increasing
: density will give less wetted surface.

Ummm, wouldn't wetted surface remain the same? Or are you saying the denser water would result in the kayak riding higher and therefore presenting a slimmer profile to the water?

I would think increased density would result in more drag. Harder to push through, though maybe not perceptible.

In a race, this is a moot point
