Abstract
A deep trolling apparatus includes a pair of supports between which there is mounted a reel on which a trolling line is wound for paying out and retrieving the line. A slip clutch assembly couples the reel to a rotatable axle extending through the reel hub for providing an adjustable drag for the control line when the axle is held in a stationary position. In the preferred embodiment, the slip clutch assembly takes the form of a lubricious polymeric tapered bushing having slotted sidewalls and seated in a similarly tapered aperture formed in the hub of the reel with the bushing surrounding the axle. The bushing can be adjustably secured to the hub such that the gripping force between the interior surface of the bushing and the axle is varied for adjusting the drag. In one embodiment of the invention the reel axle is integral with a manually actuated crank arm for rotating the reel and one of the reel supports includes a locking member for selectively locking the arm in a fixed position. According to one aspect of the invention, a trolling line guide wheel mounted on an extension boom from the base of the reel supports includes a guide for assuring that the trolling line is maintain…
