Abstract
A paddle for manually propelling a canoe or the like. The paddle includes the usual grip member establishing the upper end thereof and the usual blade member establishing the lower end thereof. An intermediate member is included which interconnects the grip member and the blade member with the major axis of the grip member angularly aligned with the plane of the blade member. Certain elements of the intermediate member may be rotatably connected one to the other by a longitudinally extending pivot pin. Accordingly, relative rotational movement of these elements may be effective to vary the pitch of the blade member with respect to the grip member. Quick release locking structure may also be included for selectively locking the blade member to the grip member in any one of several discrete predetermined positions.
