Tough, economical, dependable, the NRS PTK Kayak Paddle delivers excellent performance, especially for beginning boaters and captains of inflatable and sit-on-top kayaks. Rugged ABS blade and aircraft-grade coated-aluminum shaft stand the test of whitewater action. The cupped blade design gives a smooth, efficient catch with every paddle stroke. Shaft with oval indexing tells you right where the blade is in the water. The longer lengths are perfect for wider boats.
