Abstract

A trolling spreader bar is configured with a central body and a plurality of fishing lures as an assembly to mimic a small school of fish, wherein each lure can have a keel. The keel is angled to urge the lure assembly continually to one side or the other from what would be the normal straight line of travel of a trolling vessel. By attaching an angled keel directly to the lure/spreader bar one is able to easily set lines behind the vessel at varying angles and distances which greatly increase the width of the full trolling lure spread. The spreader bar can further be configured to have a counterweight directly attached to it to provide increased stability to the bar during trolling.

DETAILED DESCRIPTION OF THE INVENTION

(26) The following detailed description is of the best currently contemplated modes of carrying out exemplary embodiments described herein. The description is not to be taken in a limiting sense, but is made merely for the purpose of illustrating the general principles of embodiments described herein, the scope of which should be understood with reference to the claims.

(27) Broadly, embodiments described herein provide a system, method and apparatus for trolling that improves the spread, and thereby the number of lures that may be pulled behind a trolling vessel while fishing. By attaching an angled keel 14 or rudder directly to a lure/spreader bar, one is able to easily set lines behind the boat at varying angles and distances which greatly increase the width of a full trolling lure spread.

(28) As seen in reference to FIG. 1, a spreader bar 10 according to aspects of an exemplary embodiment is shown. The spreader bar 10 includes an elongated central body 12, or hub and a spreader bar 10 or rod 18, 20 that extends laterally from the central body 12, or hub. The central body 12 may be in the form of a fish bait. The central body 12 has a keel 14 that extends from the central body 12 at an angle relative to a longitudinal axis of the central body 12.

(29) The keel 14 is angled such that the central body 12 is guided laterally outwardly from the direction of travel of the fishing vessel 32 while trolling. The keel 14 angle may be adjustable relative to the body. The keel 14 may extend from a dorsal or ventral surface of the central body 12 or through the body. The central body 12 may also be configured with a lateral fin 15 to improve longitudinal stability and provide planeing lift. Additionally, the lateral fin 15 may be adjustable to control the depth at which the lure assembly may travel when trolling.

(30) As seen in reference to FIG. 2, a trolling configuration for a fishing vessel 32 according to aspects of an exemplary embodiment is illustrated. The trolling vessel 32 may be configured with a plurality of outriggers 34 extending laterally from the starboard and port sides of the vessel 32. With an exemplary spreader bar 10, the fishing lines 16 extend in a straight path from the stern of the vessel 32 and its direction of travel. The spreader bar 10 is configured with a plurality of lures 26 disposed in a spaced apart relation to replicate the schooling habits of a bait fish. The lures 26 are configured with one or more hooks so as to catch a game fish that may strike the lure 26. The lures 26 may also include a hooked natural bait, such as a squid, a crustacean, a baitfish, and the like.

(31) In certain embodiments, a plurality of fishing lines 16 each carrying the aforementioned spreader bar 10 and lures 26 may be extended from the stern of the vessel 32. This enhances the ability of the trolling vessel 32 to replicate a large school of bait fish and thereby provide better opportunities to attract and catch a game fish. When employing a spreader bar 10 lure assembly, the lures 26 carried by the spreader bar 10 are urged outwardly by the keel 14 as the trolling vessel 32 pulls the spreader bar 10 through the water.

(32) The spreader bar 10 has a first rod 18 and a second rod 20 that extend laterally from the central body 12 and may have a rearward sweep. A bait lure 26 may be operatively attached to ends of the first rod 18 and/or second rod 20. In addition, a plurality of bait lures 26 may be interconnected by a line 28 extending between an aft end of a preceding bait lure 26 and a front end of a succeeding or following bait lure 26 so as to replicate a school of fish bait, such as bait fish, mollusks, worms, squid, crustaceans, and the like.

(33) As shown in FIG. 4B, in some embodiments, a bait lure 26 is attached to the first rod 18 and/or second rod 20, each bait lure 26 possessing wings to provide a counterweight/lift for the spreader bar. This counterweight/lift provides lift and stability to the spreader bar. The body of the bait lure 26 can have a shape comprising a flat top (facing upward from a geometric plane defined by a surface of the water) and a contoured bottom (facing downward from a geometric plane defined by a surface of the water). For instance, the contoured bottom can have a first concave segment leading to a radius located at a central position of the bait lure 26 body. The contoured bottom can have a second concave segment leading to the radius. The first concave segment and the second concave segment can subtend each other. The mass of the bat lure 26 provides downward weight to the arm 18, 20 as the contoured bottom generates lift for the arm 18, 20. The first rod 18 and/or second rod 20 can have any number of such bait lures 26. A first of such bait lure 26 can be the same or different (in size, weight, composition, configuration, and/or location along the rod) from that of a second bait lure 26.

(34) In operation the angle keel 14 directs the lure/spreader bar 10 to one side or the other of the trolling vessel. Depending on the trolling velocity and weight of the spreader bar 10 and associated lures, the water pressure exerted on the angled keel 14 may cause the lure to become un-level and unstable as it is drawn through the water. Accordingly, a counterweight 24 may be provided to act against this pressure and keeps the lure level while tracking through or across the top of the water. The counterweight 24 may be operatively coupled to the first end or the second end of the spreader bar 10. Preferably the counterweight 24 is carried within the body of a bait lure 26 attached to the first and second ends of the spreader bar 10. In a preferred embodiment, the counterweight 24 is carried on the outward end of the arm 18, 20 relative to the lure assembly's 10 direction of travel so as to counteract the pressure applied to the angled keel 14. The body of the lead inboard lure 26 facilitates leveling as it planes on the water surface. The trailing lure bodies 26 serve to drag the rig and prevent “walking” or flipping of the rig in the water.

(35) In use, a fisherman would attach an angled keel 14 lure/spreader bar 10 to his fishing line 16. The fisherman may then, while the vessel 32 is moving forward, let the lure assembly 10 out behind the vessel 32. When tension is applied to the fishing line 16 the angled keel 14 would direct the lure assembly off of its normally straight path to a new position laterally to the side of the vessel's 32 path of travel, thereby solving the problem of only having lures 26 dragging directly behind the pulling point on the vessel 32. He would instead have lures 26 tracking well out to each side of the vessel 32 running in clean water giving him a wider spread of fish bait for more game fish to see and strike.

(36) In certain embodiments, the angled keel 14, stabilizing counter weight and corresponding lifting bait can be applied to surface trolling lures 26 such as spreader bars. By attaching an angled keel 14 directly to the lure/spreader bar 10 one is able to easily set lines behind the vessel at varying angles K and lateral separation P, which greatly increase the width of the full trolling lure spread.

(37) Rotatable Base Plate

(38) In an aspect, a rotatable base plate described herein is circular or essentially circular to permit rotation about a central axis.

(39) In another aspect, the elongated central body comprises two threaded holes to accommodate screws for securing the rotatable base plate to the elongated central body in an essentially locked position or state for setting the adjustable keel at a desired angle.

(40) In certain embodiments, a rotatable base plate described herein comprises a plurality of pairs of grooves or notches.

(41) In an aspect, embodiments described herein do not comprise a screw or screws at a central point of the rotatable base plate. In another aspect, embodiments of rotatable base plates described herein do not rotate about a screw centrally located relative to the body of the rotatable base plate. In preferred embodiments, the screws securing the rotatable base plate to the elongated body are located near or toward the outer edge or perimeter or circumference of the rotatable base plate.

(42) In an aspect, embodiments described herein do not comprise intersecting grooves on the rotatable base plate or elsewhere for purposes of adjusting the keel. Embodiments described herein do not comprise an “X” shaped groove or channel.

(43) In a further aspect, embodiments described herein do not comprise any grooves or channels which intersect with, or are overlaid on, the center of the rotatable base plate.

(44) In reference to FIGS. 5A and 5B, an exemplary rotatable base plate 40 comprises a plurality of pairs of grooves or notches 41 through which screws 42 extend into the elongated central body to secure the rotatable base plate to the elongated central body 12. In an aspect, when the screws are loosened, the rotatable base plate may be freely rotated about a central axis such that the screws 42 may be tightened for setting the adjustable keel 14 at a desired position or angle.

(45) By way of illustration, pairs of corresponding grooves or notches are depicted as 41a, 41b, 41c and 41d. By further way of illustration, a configuration is depicted wherein the keel 14 is positioned by securing the rotatable base plate 40 with screws 42 in a pair of grooves or notches 41b.

(46) Thus, as the rotatable base plate 40 is rotated and secured into different positions, e.g. 41a, 41b, etc., the keel 14 is adjusted to a new position/angle.

(47) In an aspect, the grooves or notches 41 of the rotatable base plate 40 are not threaded. In another aspect, consecutive grooves or notches 41 of the rotatable base plate are connected by a sliding groove (or sliding notch) 43 through which a loosened screw 42 may travel between consecutive grooves or notches 41. In an aspect, the sliding grooves/notches 43 are not threaded. In yet a further aspect, the grooves or notches 41 are essentially the same size as the major diameter of the screws 42 inserted therein or of the shanks of the screws 42 inserted therein.

(48) In certain embodiments, the grooves or notches 41 are, at the outer surface of the rotatable base plate 40, tapered or otherwise beveled to accommodate the heads of the screws 42 inserted therein, i.e. such that the screws 42 are countersunk or essentially countersunk into the rotatable base plate 40 when tightened, the outer surface of the rotatable base plate 40 being the surface having the keel 14 affixed thereto.

(49) FIG. 5C depicts an embodiment of the rotatable base plate 40 which is not secured to the elongated body 12.

(50) FIG. 5D depicts the elongated body 12 when the rotatable base plate 40 is not secured thereto. The elongated body 12 has an area 45 in which the rotatable base plate is positioned or otherwise placed. The elongated body 12 comprises threaded holes 44 in such area in which the screws 42 may be tightened to secure the rotatable base plate 40 thereto.

(51) In reference to FIGS. 6A-6C, certain embodiments of a rotatable base plate 40 described herein comprise a pair of trench-like grooves 50. In an aspect, when the screws 42 are loosened and the rotatable base plate 40 is rotated, the screws 42 travel through the trench-like grooves 50 to adjust the keel 14 to a desired angle at which point the screws 42 may be tightened to set the desired keel angle.

(52) In certain embodiments, the trench-like grooves 50 are of a thickness equal to or essentially equal to the major diameter of a screw 42 to be inserted therein, or equal to or essentially equal to the diameter of the shank of a screw 42 to be inserted therein.

(53) In certain embodiments, the trench-like grooves 50 are, at the outer surface of the rotatable base plate 40, tapered or otherwise beveled to accommodate the heads of the screws 42 inserted therein, i.e. such that the screws 42 are countersunk or essentially countersunk into the rotatable base plate 40 when tightened.

(54) In embodiments comprising trench-like grooves 50 instead of discrete grooves or notches 41, the screws 42 may be secured at any position along the trench-like grooves 50, permitting many more angles/positions for the keel 14 to be adjusted to.

(55) In reference to FIGS. 7A-7C, certain embodiments of a rotatable base plate described herein comprise a single trench-like groove 60. In an aspect, when the screws 42 are loosened and the rotatable base plate 40 is rotated, the screws 42 travel through the trench-like groove 60 to adjust the keel 14 to a desired angle at which point the screws 42 may be tightened to set the desired keel angle.

(56) In certain embodiments, the trench-like groove 60 is of a thickness equal to or essentially equal to the major diameter of a screw 42 to be inserted therein, or equal to or essentially equal to the diameter of the shank of a screw 42 to be inserted therein.

(57) In certain embodiments, the trench-like groove 60 is, at the outer surface of the rotatable base plate 40, tapered or otherwise beveled to accommodate the heads of the screws 42 inserted therein, i.e. such that the screws 42 are countersunk or essentially countersunk into the rotatable base plate 40 when tightened.

(58) In embodiments comprising a trench-like groove 60 instead of discrete grooves or notches 41, the screws 42 may be secured at any position along the trench-like grooves 50, permitting many more angles/positions for the keel 14 to be adjusted to.

(59) In certain embodiments, an adjustable keel 14 described herein is fixed to a rotatable base plate 40. In a preferred embodiment, an adjustable keel 14 and a rotatable base plate 40 described herein are provided together as a single, molded or machined component.

(60) Referring to FIG. 9A, the spreader bar described herein may comprise one or more teaser baits 90 (also referred to as “birds”) with wings 91 that extend from the body of teaser bait 90.

(61) In an aspect, a teaser bait 90 provides an alternative means of counter-weighting and planing lift and may be used in combination with or in place of a counterweight 24. In a preferred embodiment, the teaser bait(s) 90 is/are composed of a dense plastic material. In an aspect, however, any material may be used to mold or otherwise manufacture the teaser bait(s) 90.

(62) In an aspect, the teaser bait(s) 90 weigh(s) about 0.5 ounces to about 2.0 ounces, preferably about 0.75 ounces to about 1.5 ounces, more preferably about 1.0 ounce.

(63) It has been found that, when using a configuration as depicted in FIG. 9A, wherein the teaser baits 90 are used as substitutes for counterweighting and lift bait, the teaser bait on the inboard rod provides sufficient lift such that when it is combined with the bodyweight of the dense plastic teaser bait on the outboard rod acting as a counterweight, the lure is able to perform desirably in most sea conditions such that target species are attracted and that the lure does not walk or otherwise behave in an undesirable manner.

(64) In an aspect, one or more of the lures 26 preferably comprises a hook 100. In certain preferred embodiments, each lure 26 comprises a hook.

(65) By way of illustration and for simplicity, FIG. 9B depicts an embodiment comprising a hook 100 on each lure 26. This embodiment is not intended to be limiting. In some embodiments, the teaser bait(s) 90 may comprise a hook 100. In other embodiments, the teaser bait(s) do(es) not comprise a hook.

(66) FIG. 9C depicts an embodiment comprising a hook only on the rear-most lure in an alternative preferred embodiment.

(67) In an aspect, a hook may be affixed to any location on a lure.

(68) FIG. 9D depicts an embodiment in which a hook is affixed to a lure at a point which is distal relative to the lure which it trails.

(69) In some embodiments, a hook may trail directly behind a lure, as depicted in FIG. 9D. In other embodiments, a hook may extend downwardly from any point on the underside of a lure.

(70) By way of illustration and for simplicity, FIG. 3C similarly depicts an embodiment comprising a hook 100 on each lure 26. This embodiment is not intended to be limiting.

(71) FIG. 3B depicts an embodiment comprising a hook only on the rear-most lure in an alternative preferred embodiment.

(72) In preferred embodiments, the rotatable base plate does not need to be lifted off of the elongated central body when adjusting the keel angle.

(73) In a preferred embodiment, the adjustable keel is not secured to the rotatable base plate using a screw.

(74) In a preferred embodiment, a screw is not inserted through or into the center of the rotatable base plate.

(75) In a preferred embodiment, the keel 14 is affixed securely to the rotatable base plate 40 and any adjustment or repositioning of the keel is performed by adjusting or repositioning the rotatable base plate 40 by loosening the screws 42 and rotating the rotatable base plate 40 to a new position by securing the screws 42 at a different position 41.

(76) It will be apparent to those skilled in the art that numerous modifications and variations of the described examples and embodiments are possible in light of the above teachings of the disclosure. The disclosed examples and embodiments are presented for purposes of illustration only.

(77) Other alternate embodiments may include some or all of the features disclosed herein. Therefore, it is the intent to cover all such modifications and alternate embodiments as may come within the true scope of this invention, which is to be given the full breadth thereof. Additionally, the disclosure of a range of values is a disclosure of every numerical value within that range, including the end points.

(78) A person of ordinary skill in the art would understand and appreciate that a keel adjusted to a position of 45 degrees relative to the longitudinal axis of the elongated central body would result in the “strongest” keel angle. That is, an angle of 45 degrees causes the lure to be pushed the furthest distance laterally outwardly from the fishing vessel.

(79) In an aspect, the rotatable base plate may be rotated to set the adjustable keel at any desired angle.

(80) In certain embodiments, a rotatable base plate may be rotated such that the adjustable keel is set at an angle of 45 or 40 or 35 or 30 or 27.5 or 25 or 22.5 or 20 or 15 or 10 or 5 degrees to the left or to the right, relative to the longitudinal axis of the elongated central body, or parallel to the longitudinal axis of the elongated central body.

(81) It should be understood, of course, that the foregoing relates to exemplary embodiments and that modifications may be made without departing from the spirit and scope of the invention as set forth in the claims.

(82) The features of the trolling spreader bar described herein have been found to act in concert to achieve a surprisingly stable, self-righting, and level trolling means, which is unexpectedly effective in attracting target species in the water.

(83) A skilled artisan would understand through use of embodiments described herein that use of the ventral keel keeps the angled area of the keel below the surface of the water even during the planing action achieved under typical trolling speeds.

(84) Additionally, the skilled artisan would appreciate that counterweighting causes the outboard end of the spreader bar to be held down on the surface of the water as pressure from the keel tries to roll it over, creating critical stability—i.e., the counter weight also pulls down the outboard arm of the spreader bar.

(85) FIG. 10 depicts an embodiment wherein a counterweight is directly attached to the outboard rod of the spreader bar to help keep the bar held down on the surface of the water. FIG. 10 shows the counterweight attached at or near a distal end of the outboard rod; however, it is understood that the counterweight can be attached to any portion of the outboard rod. FIG. 10 also shows the counterweight attached to a first rod of the spreader bar; however, it is understood that the spreader bar can have a second counterweight attached to the second rod of the spreader bar. In addition, any one or combination of the first rod and second rod can have any number of counterweights. The counterweight can be a weighted material (e.g., metal, plastic, ceramic, etc.) that is wrapped around, welded to, riveted, screwed, attached via adhesive, etc. to the outboard rod. In addition, or in the alternative, the counterweight can be a denser portion of the rod. For instance, the rod can be made from a composite material, wherein a portion of the rod that is the counterweight can be made of denser material. As another example, the rod can be made of a single material but have a bulged formation at a location along the rod to form the counterweight. As noted above, the spreader bar can have a plurality of counterweights. A first counterweight can be the same or different (in size, weight, composition, configuration, and/or location along the rod) from that of a second counterweight.

(86) Moreover, the first bait on the inboard end of the spreader bar has a firm body with a float in its body causing it to act as a planing mechanism to lift the end as the keel tries to drive it under water, creating critical stability.

(87) Meanwhile, the plurality of bait lures causes a steady and even aft ward pressure on the entire spreader bar therefore keeping it running uniformly in a forward direction and not twisting.

(88) The angled lateral fins mounted to the elongated central body cause the main hub area (i.e., the elongated central body) to be lifted during forward motion in rough seas, while the aft sweep causes the spread bar system to be more stable in preventing “walking” or “flipping”.

(89) Embodiments described herein have been found to achieve superior results as compared to embodiments which comprise rudders or rudder systems. A keel allows an entire object to be pushed laterally, whereas a rudder system results in steering with limited ability for sideways movement. The adjustable keel of embodiments described herein therefore permits a skilled artisan to compensate for water conditions and adjust location of the trolling spreader bar in the water to attract different target species and accommodate for marine conditions.

(90) In an aspect, embodiments described herein have been found to obviate the need for outriggers, which are expensive and complicated, especially for novice or recreational fisherman. The typical novice fisherman likely does not own or have access to an outrigger. Thus, embodiments described herein solve an unmet need in the marketplace for more cost-efficient and accessible means of trolling.

(91) As used in the following Examples, the term “stability” should be understood as denoting the lure behavior as it skips across the surface of the water under forward movement and momentum.

(92) A skilled artisan would understand that the terms “walking”, “crabbing”, and “tumbling” denote undesirably unstable lures which skip across the water's surface significantly. In particular, these terms denote a process wherein forward motion and wave activity cause the ends of the rod or bar to lift slightly off the water in an alternating pattern, which can continue and become exaggerated or excessive. While some walking may be acceptable for effective fishing, excessive or continued walking is undesirable as it will render a lure unfishable and fail to attract target species negated by the activity.

(93) A skilled artisan would understand that the term “self-righting” or similar terms denotes a lures ability to return to the surface and resume normal function after disappearing subsurface due to, for example, rough waters. In the Examples that follow, the lures tested were forced to flip to determine their ability to self-right.

(94) The following examples serve to illustrate certain aspects of the disclosure and are not intended to limit the disclosure.

(95) As seen in reference to FIG. 11, a spreader bar 10 is shown. The spreader bar 10 includes an elongated central body 12 and a spreader bar 10 or rod 18, 20 that extends laterally from the central body 12. The central body 12 may be in the form of a fish bait. It is contemplated that the central body 12 may not have a keel attached thereto. The central body 12 may be configured with at least one lateral fin 15 to improve longitudinal stability and provide planing lift. Additionally, the at least one lateral fin 15 may be adjustable to control the depth at which the lure assembly may travel when trolling. In further reference to FIG. 11, the spreader bar 10 has a first rod 18 and a second rod 20 that extend laterally from the central body 12 and have a rearward sweep. A bait lure 26 may be operatively attached to ends of the first rod 18 and/or second rod 20. In addition, a plurality of bait lures 26 may be interconnected by a line 28 extending between an aft end of a preceding bait lure 26 and a front end of a succeeding or following bait lure 26 so as to replicate a school of fish bait, such as bait fish, mollusks, worms, squid, crustaceans, and the like. At least one bait lure 26 has at least one keel 114 that extends from the bait lure 26 at an angle relative to a longitudinal axis of the bait lure 26. It is contemplated for each bait lure 26 has at least one keel 114 that extends from each bait lure 26 at an angle relative to a longitudinal axis of each bait lure 26. In operation, the at least one keel 114 directs each bait lure 26 and the spreader bar 10 to one side or the other of the trolling vessel 32. When tension is applied to the fishing line 16, the angled keel(s) 114 direct the lure(s) 26 off a normally straight path to a new position laterally to one side of the vessel's 32 path of travel, thereby solving the problem of only having lures 26 dragging directly behind the pulling point of the vessel 32. Any one or combination of bait lures 26 may also be configured with at least one lateral fin 115 to improve longitudinal stability and provide planing lift. Additionally, the at least one lateral fin 115 may be adjustable to control the depth at which the lure assembly may travel when trolling.

(96) In an aspect, each bait lure may comprise two threaded holes to accommodate screws for securing a rotatable base plate to each bait lure in an essentially locked position or state for setting the adjustable keel at a desired angle. In preferred embodiments, the screws securing the rotatable base plate to the bait lure are located near or toward the outer edge or perimeter or circumference of the rotatable base plate.

(97) In reference to FIGS. 12A and 12B, an exemplary rotatable base plate 40 comprises a plurality of pairs of grooves or notches 41 through which screws 42 extend into a bait lure 26 to secure the rotatable base plate to the bait lure 26. In an aspect, when the screws are loosened, the rotatable base plate may be freely rotated about a central axis such that the screws 42 may be tightened for setting the adjustable keel 114 at a desired position or angle.

(98) By way of illustration, pairs of corresponding grooves or notches are depicted as 41a, 41b, 41c and 41d. By further way of illustration, a configuration is depicted wherein the keel 114 is positioned by securing the rotatable base plate 40 with screws 42 in a pair of grooves or notches 41b.

(99) Thus, as the rotatable base plate 40 is rotated and secured into different positions, e.g. 41a, 41b, etc., the keel 114 is adjusted to a new position/angle.

(100) In an aspect, the grooves or notches 41 of the rotatable base plate 40 are not threaded. In another aspect, consecutive grooves or notches 41 of the rotatable base plate are connected by a sliding groove (or sliding notch) 43 through which a loosened screw 42 may travel between consecutive grooves or notches 41. In an aspect, the sliding grooves/notches 43 are not threaded. In yet a further aspect, the grooves or notches 41 are essentially the same size as the major diameter of the screws 42 inserted therein or of the shanks of the screws 42 inserted therein.

(101) In certain embodiments, the grooves or notches 41 are, at the outer surface of the rotatable base plate 40, tapered or otherwise beveled to accommodate the heads of the screws 42 inserted therein, i.e. such that the screws 42 are countersunk or essentially countersunk into the rotatable base plate 40 when tightened, the outer surface of the rotatable base plate 40 being the surface having the keel 114 affixed thereto.

(102) FIG. 12C depicts a bait lure 26 when the rotatable base plate 40 is not secured thereto. The bait lure 26 has an area in which the rotatable base plate is positioned or otherwise placed. The bait lure 26 comprises threaded holes 44 in such area in which the screws 42 may be tightened to secure the rotatable base plate 40 thereto.

(103) In reference to FIGS. 13A-13B, certain embodiments of a rotatable base plate 40 described herein comprise a pair of trench-like grooves 50. In an aspect, when the screws 42 are loosened and the rotatable base plate 40 is rotated, the screws 42 travel through the trench-like grooves 50 to adjust the keel 114 to a desired angle at which point the screws 42 may be tightened to set the desired keel angle.

(104) In certain embodiments, the trench-like grooves 50 are of a thickness equal to or essentially equal to the major diameter of a screw 42 to be inserted therein, or equal to or essentially equal to the diameter of the shank of a screw 42 to be inserted therein.

(105) In certain embodiments, the trench-like grooves 50 are, at the outer surface of the rotatable base plate 40, tapered or otherwise beveled to accommodate the heads of the screws 42 inserted therein, i.e. such that the screws 42 are countersunk or essentially countersunk into the rotatable base plate 40 when tightened.

(106) In embodiments comprising trench-like grooves 50 instead of discrete grooves or notches 41, the screws 42 may be secured at any position along the trench-like grooves 50, permitting many more angles/positions for the keel 114 to be adjusted to.

(107) In reference to FIGS. 14-14B, certain embodiments of a rotatable base plate described herein comprise a single trench-like groove 60. In an aspect, when the screws 42 are loosened and the rotatable base plate 40 is rotated, the screws 42 travel through the trench-like groove 60 to adjust the keel 114 to a desired angle at which point the screws 42 may be tightened to set the desired keel angle.

(108) In certain embodiments, the trench-like groove 60 is of a thickness equal to or essentially equal to the major diameter of a screw 42 to be inserted therein, or equal to or essentially equal to the diameter of the shank of a screw 42 to be inserted therein.

(109) In certain embodiments, the trench-like groove 60 is, at the outer surface of the rotatable base plate 40, tapered or otherwise beveled to accommodate the heads of the screws 42 inserted therein, i.e. such that the screws 42 are countersunk or essentially countersunk into the rotatable base plate 40 when tightened.

(110) In embodiments comprising a trench-like groove 60 instead of discrete grooves or notches 41, the screws 42 may be secured at any position along the trench-like grooves 50, permitting many more angles/positions for the keel 114 to be adjusted to.

(111) In certain embodiments, an adjustable keel 114 described herein is fixed to a rotatable base plate 40. In a preferred embodiment, an adjustable keel 114 and a rotatable base plate 40 described herein are provided together as a single, molded or machined component.

(112) In preferred embodiments, the rotatable base plate 40 does not need to be lifted off of the bait lure 26 when adjusting the angle of the keel 114

(113) In a preferred embodiment, the adjustable keel 114 is not secured to the rotatable base plate 40 using a screw.

(114) In a preferred embodiment, the keel 114 is affixed securely to the rotatable base plate 40 and any adjustment or repositioning of the keel 114 is performed by adjusting or repositioning the rotatable base plate 40 by loosening the screws 42 and rotating the rotatable base plate 40 to a new position by securing the screws 42 at a different position 41.

(115) A person of ordinary skill in the art would understand and appreciate that a keel adjusted to a position of 45 degrees relative to the longitudinal axis of each bait lure would result in the “strongest” keel angle. That is, an angle of 45 degrees causes the lures to be pushed the furthest distance laterally outwardly from the fishing vessel.

(116) In an aspect, the rotatable base plate may be rotated to set the adjustable keel at any desired angle.

(117) In certain embodiments, a rotatable base plate may be rotated such that the adjustable keel is set at an angle of 45 or 40 or 35 or 30 or 27.5 or 25 or 22.5 or 20 or 15 or 10 or 5 degrees to the left or to the right, relative to the longitudinal axis of each bait lure, or parallel to the longitudinal axis of each bait lure.

(272) For this disclosure the following definitions are provided:

(273) Bird=Single Bait body with wings

(274) Stability—this term describes the lure behavior as it skips across the surface of the water under forward movement. Terms such as walking, crabbing, and tumbling are sometimes used. These terms refer to a process when forward motion and wave action cause the ends of the rod/bar to lift slightly off the water in an alternating pattern, as this pattern continues it can become exaggerated and excessive.—Note: a small amount of this is acceptable for effective fishing but not excessive and continual. Too much instability will render a lure unfishable as its characteristics of attracting target species are negated by its activity.

(275) Stability Scale: Very Good—Good—Ok—Poor—Very Poor

(276) Self Righting—This is critical for performance in very rough sea conditions(3-5′ waves). If the lure completely flips while trolling causing it to disappear subsurface, it is critical that it returns to the surface and resumes normal function. For this test the lure was forced to flip to observe self righting.
