The most popular Cataract oar blade, the Cataract Magnum II Oar Blade features a high-grade urethane body molded around a stiff composite core, giving it superior strength. And it floats!

• The spline that goes inside the oar shaft is grooved to prevent silt build-up that can make it difficult to remove the blade.
• The 7″ wide blade moves a lot of water per stroke.
• The ribbed surface adds strength and reduces blade flutter.
• Push button locks the blade in Cataract, Carlisle and Sawyer 1 7/8″ oar shafts. Easily switch out blades without tools!
