Abstract
A directional guide for a spreader bar includes a body extending along a longitudinal axis. The body includes a first fin and a second fin spaced apart from the first fin. The first and second fins are coupled to the body and are configured to control a vertical position of the body in water through which the body is moving. Grooves are formed in the body. The grooves include a first groove extending along the longitudinal axis of the body, a second groove crossing the first groove and a third groove crossing the first groove. A keel is rotatably coupled to the body. The keel is configured to rotate between the first groove, the second groove, and the third groove. The keel is configured to control a lateral position of the body in water through which the body is moving.
