Abstract

An exemplary paddle includes a central shaft having a first end and a second end. One or more lateral blades extend laterally from the central shaft, and each lateral blade including a geared end positioned adjacent the central shaft and a distal end opposite the geared end. Each lateral blade provides a blade gear at the geared end. A drive shaft is movably positioned within the central shaft and operatively coupled to the one or more lateral blades such that rotation of the drive shaft about a central axis rotates the one or more lateral blades about a corresponding one or more blade axes. The one or more lateral blades are able to move between a horizontal position and a vertical position via independent actuation.
