Abstract
A kayak paddle with improved performance features is provided. The kayak paddle includes a smaller diameter shaft than that generally used. This allows the placement of grips on the shaft. The rips have one or more finger and thumb indentations such that the kayaker can position his hand easily and securely on the kayak paddle. The grips may be rotated around the shaft in order to position them at a location which is comfortable to the user. Also provided are paddle blades which may be rotated around the shaft such that they can be positioned in the most beneficial location for the user and the particular activity. Also disclosed are structures on the blades, including ribs and compartments, which direct water flow across the blade to reduce cavitation.
