A blade for a kayak paddle with a shaft can include a body extending from the shaft to a blade tip. The body has a cross-sectional profile separated at a chord line into a top section with an upper surface and a bottom section with a lower surface. The paddle can also include a shoulder section smoothly transitioning between the shaft and the blade body. The top section of the cross-sectional profile can be thicker than the bottom section and the upper surface exhibits more curvature than the lower surface, thereby increasing fluid flow speed over the upper surface to generate a lift force when the body is moved through water.
