The Classic Cataract Blade is a durable, buoyant oar blade. This blade will do great in almost any condition. Also referred to as the "Floating Blade" While all of our oar blades float, none bob so vigorously as the Cataract(TM). Hence the blade&';s nickname: "floater." CataractA(R) Oars offers an optional tip protector to envelop the Cataract(TM) blade&';s lower extremity in a rugged sheath of dip-molded rubber. Great for every season, these blades can take a beating and keep on competing. 6 1/4" wide, 27.5" long, the Cataract(TM) blade is super tough and incredibly buoyant. Extra buoyancy causes the blade to bob on the surface keeping oars in the oar locks when letting go to pull in that trophy fish. Add on the Cataract Oar Blade Protector for even more bombproof durability. The grooved blade insert prevents silt buildup inside the oar shaft and makes removal easy. The easy-to-use push-button system securely locks the 1-5/8" blade insert in place and makes it a breeze to switch out the blade when needed. No tools necessary. Built for CataractA(R) Oars SGG(TM), SGX(TM), and X Wound(TM) shafts.
