Actually, a kayak would look very little like an airfoil to the flow. You'll notice that the wings on a sailplane are very long. Thiss causes the flow to be mainly fore - aft over most of the wing (2D flow). Spanwise (3D) flow detracts from the airfoil's ability to do its job. Also flow from the bottom to the top, unless used to energize flow over the top efficiently, will lessen the effect of the airfoil shape.

A kayak would probably be modelled closer to two cones joined by a short cylinder section than an airfoil (wing) shape. Alot of what we've discussed really doesn't apply except in small amounts. A slight sideways drift of the boat will occur, but it is of very limited magnitude due to 3D flow effects.
