Abstract: A soft bait fish lure includes an elongated body having a head and a rear along a longitudinal axis. The body tapers laterally to a reduced tail portion toward the rear, then flares laterally into an enlarged tail at the rear. Optionally, the reduced tail portion is flexible in a lateral direction. The enlarged tail may have a tapered top and tapered bottom, each formed from two intersecting faces, such that the enlarged tail forms a substantial diamond-shape in cross-section perpendicular to the longitudinal axis. Optionally, each of the faces includes a contour terminating in an edge proximate said rear such that fluid flowing over said enlarged tail forms a vortex at each said face. Optionally, the rear forms a distal surface including a lateral indentation at the intersection of the tapered top and tapered bottom.

Abstract: A drogue attachment consisting of two symmetrical shaped arms is affixed to one end of a shaft, that end of the shaft being attached to a fishing line. The other end of the shaft is tied to a leader, which is in turn tied to a baited or lure-equipped fish hook device. When the fish hook device is pulled through the water by a fish, water opens the shaped arms; when pulled in the other direction by the angler, the arms fold in against the shaft.

Abstract: A fishing lure or decoy is provided, the lure having a casement for receiving an electronic insert. The insert is operated by a microcontroller programmed to implement at least one sequence of operation implemented by at least one of a LED light emitter, a vibration-producing device and an audio transducer. An electrical power supply in the insert provides power to the devices and microcontroller, and a pair of externally exposed contacts switches the microcontroller ON when bridged by water containing electrolytes, as would be found in a fishing area. This also produces an electrical field around the lure, this electrical field also serving to simulate living food creatures to entice fish to bite the lure.

Abstract: An adjustable-depth crankbait fishing lure for use in catching fish at user-selectable depths. The crankbait fishing lure is made of a buoyant yet hard body having the shape and general appearance of a bait fish. Attached to the body are at least one fish hook and a means to attach the body to a fishing line. Pivotable lateral fins are located at each side of the body and are user adjustable for either water surface operation or operation at varying depths.

Abstract: Artificial fishing lure which has a flexible resilient core (10) surrounded by an elongated flexible body (12). One or more hooks (18) are installed in the core (10) substantially perpendicular to core (10) by way of apertures (24a) and (24b). The core (10) provides longevity to the lure for small and large lures when cast from rod and reel or trolled. Large of heavy lures of this design can be cast with great distances. Grooves (14) in the elongated flexible body (12) and core (10) create a predetermined or erratic motion during retrieval through the water. This action can simulate that of any type of prey including a wounded prey.

Abstract: A flexible nose assembly for an underwater vehicle provides increased energy-absorbing capabilities and facilitates recovery and handling of the vehicle. The flexible nose assembly includes a flexible nose cap, at least one retrieval device, and at least one cable that is strong in tension, yet weak in compression which is coupled between the retrieval device and the UUV body. The flexible nose cap has a gap formed therein allowing the communication of environmental water into the region between the vehicle body and the nose cap. Optionally, the retrieval device may be recessed into the flexible nose assembly, thereby reducing hydrodynamic drag and overall vehicle length. Energy-absorbing ballast can be positioned within the nose cap in order to further enhance survivability.

Abstract: A fishing lure is described containing a cast of a natural bait encased in a castable transparent material designed in hydrodynamically correct shapes and to operate at different depths by utilizing an adjustable buoyancy device. A cast of a natural bait being the embodiment of a natural bait in the form of a castable material taken from the cast of a natural bait and then painted, to which an adjustable buoyancy device is incorporated by containment within the lure or attachment to the lure of a sealed air chamber wherein the adjustable portion consists of a cylinder which is threaded on the inside to accommodate a set screw/gasket seal combination. Rotation of the set screw varies the lure's buoyancy by compressing the air in the air chamber thus varying the fluid displacement volume of the lure and also changing the center of gravity of the lure. Alternatively, the cast can be of a part of the natural bait or a section or surface texture of the bait.

Abstract: A directionally controllable fishing lure enables an angler to cast the lure to a desired area, with the lure traveling an arcuate path to the left or right upon retrieval. The direction of turn is determined by the angler, depending upon the rigging of the lure. The present lure has an elongate body with angularly truncated faces at each end thereof. The two faces are angled in opposite directions to one another, and the lure body is ballasted so that the two faces are always angled to one side when the lure is floating in the water, rather than facing upwardly or downwardly. The angularly truncated ends produce an asymmetrical hydrodynamic reaction as the lure is drawn through the water, causing the lure to turn in one direction or the other. If the angler attaches the fishing leader or line to the first end, the lure will travel in an arcuate path to the angler's right (or to the left, when considered in the direction of travel of the lure).

Abstract: A rising crank bait lure includes a body, a forward sloping lip, at least one hook, and a line loop. The body preferably has the shape of a minnow, but could be shaped as any other fish. The body may be either a single piece or a multiple piece design. The forward sloping lip may be attached to a front of the body, to a top of the body at substantially a front thereof, or to a bottom of the body at substantially a front thereof. The extended end of the lip is preferably rounded to decrease drag. The line loop extends from a front of the body for attachment of a fishing line. At least one hook is attached to a bottom of the body. The body is preferably painted to resemble a fish.

Abstract: A fishing lure provides a lateral surface run during retrieval by utilizing a generally upright front surface (A) extending across an integral body which floats or is generally of substantially neutral buoyancy. A weight (B) is carried by the lure body to adjust the balance and path traversed during retrieval and to maintain a generally upright side wall (D) in position for attachment of a line to a connector (C) located in an elongated tunnel (E) intermediate upper and lower edges of the tunnel. The method contemplates utilizing an upright front surface (A) tapering across the lure body for providing lateral direction during retrieval, together with the step of fixing a connector to an upright side from about ¼ to about ⅓ of the length of the body from the front.
