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.

A swivel assembly for mounting a downrigger to a vessel comprising:
- a base plate including means for securing said plate to a vessel, said plate having an upper surface and a first recess formed downwardly in said plate through said upper surface, interengaging means movably positioned in said recess and including a portion extending above said upper surface;
- a swivel plate rotatably secured to said base plate and including a lower surface facing said upper surface of said base plate, said swivel plate including a second recess for receiving said portion of said interengaging means to permit relative rotation of said swivel plate with respect to said base plate when said interengaging means is in a first position, said swivel plate including locking means communicating with said second recess;
- and
- means for moving said interengaging means to a second position in which said portion of said interengaging means contacts said locking means to prevent rotation of said swivel plate with respect to said base plate.
A downrigger including a swivel assembly for mounting said downrigger to a vessel comprising:
- a reel for paying out and retrieving line, said reel supported by bracket means extending upwardly from a mounting plate;
- boom means extending outwardly from said mounting plate and including means for passing said line through an end of said boom remote from said mounting plate;
- a base plate including means for securing said plate to a vessel, said plate having an upper surface and a recess formed downwardly in said plate through said upper surface, interengaging means movably positioned in said recess and extending above said upper surface;
- a swivel plate rotatably secured to said base plate and including a lower surface facing said upper surface of said base plate, said swivel plate including an annular recess for receiving the segment of said interengaging means extending above said base plate to permit relative rotation of said swivel plate with respect to said base plate when said interengaging means is in a first position, said swivel plate including locking means communicating with said annular recess;
- means for moving said interengaging means to a second position in which said segment of said interengaging means engages said locking means to prevent rotation of said swivel plate with respect to said base plate;
- and
- means for securing said mounting plate to said swivel plate.
