  • Publication number: 20130104444
    Abstract: A fly fishing rod and reel system in which the reel is positioned rearward from the proximal end of the rod so that load bearing point is repositioned to the reel and the user's forearm and not the user's wrist when casting and fish fighting. In three embodiments, the reel is attached to a positioning member that positions the reel so that its transverse axis is longitudinally aligned with the rod's longitudinal axis and the reel extends beyond the proximal end of the rod thereby creating a new fulcrum point under the user's forearm when casting and fish fighting. By positioning the reel rearward, the user's wrist can lock when casting and press the reel against the forearm to ensure proper casting technique is used. The fly line is within reach of the user's fingers and the reel may be pressed against the abdomen to create drag on the reel.
