Abstract: The swivel mount of the present invention provides a low profile swivel for a deep trolling reel which can be permanently secured to the deck of a vessel and provides incremental rotational adjustment of the deep trolling reel mounted thereto through 360.degree. at 45.degree. intervals in the preferred embodiment. The structure compactness is made possible by the use of interengaging locking mechanism extending upwardly from a base plate to engage a plurality of angularly spaced notches communicating with the outer periphery of an annular groove in a swivel plate pivotally mounted to the base plate. The locking mechanism is spring-loaded and includes a control handle extending outwardly from the base plate to releasably lock the deep troller in a desired position.
