Abstract:
A fishing lure is described, having a head with a release mechanism and a removable tail. Because the tail can be released, fish caught on hooks can be released quickly, and new tails with new hooks rapidly attached to the same head. Multiple tails may be equipped with different lure skirts, for different fish and/or different conditions, and rapidly changed out in the course of fishing. A tail including a drag chute released by a fish strike, attachable to the same head, is also disclosed. A dive wing, attachable to the removable tails, is also disclosed. Tails can include bait scent chambers and release holes and water jets to attract fish. A kit with combinations of heads, tails, dive wings, and other parts and accessories is also disclosed.

CROSS-REFERENCE TO RELATED APPLICATIONS 
     This application claims priority from U.S. Provisional Patent Application No. 60/591,249, filed Jul. 26, 2004, entitled Fishing Lure and Kit, to inventor Andrew Zuk, the contents of which are incorporated by reference herein in their entirety. 
    
    
     FIELD OF THE INVENTION 
     1. Field 
     Embodiments relate to the field of sporting equipment, and in particular, fishing lures. 
     2. Related Art 
       FIG. 1A  is a plan view of a typical fishing lure. Lure  100  includes body  110 , from which lead line  112  extends. Lure  100  also includes hook  130 . In some cases, body  110  is provided with fish-like features, for example eyes  118  or stripes  119 . Lead line  112  is typically tied to swivel  120 , to which line  122  is tied, with knot  124 . 
       FIG. 1B  is a plan view of a typical fishing lure. In some fishing lures, body  110  of lure  140  is encased in skirt  150 , which includes tentacles  152 . Lure  140  is typically equipped with a line, shown as lead line  112 , or swivel  120  at one end and hook  130  at another. 
       FIG. 1C  is a plan view of a typical fishing lure. Some fishing lures are formed of a flat body  160 , to which stripes  119  may be added. Such lures are typically equipped with ring  116  at either end. Hook  130  is typically attached to ring  116 . 
     One problem with typical fishing lures is that lines  112 ,  122  are permanently attached to body  110 , or tied with knots  124  to ring  116 . When a fish is caught, and brought on a boat, the hooks must be extracted, or sometimes the lines are cut, in order to attach new lures and hooks. Reattaching lines and unhooking fish are time-consuming processes that waste time during the important interval while fish are hitting. 
     Another problem with typical fishing lures is that it is desirable to change lures to ones of different shape, color, pattern, weight, depth or other features quickly, while fish are hitting other lines. Lures that are tied on need to be cut, and new lures re-tied, thus consuming valuable time. Also, because the design or function of each lure is a permanent part of the lure body, it can be necessary to purchase and carry a large collection of complete lures, expending money and being burdensome. 
     It is therefore desirable to have a lure which is easily removed and replaced on a line, and which can be reconfigured to perform many different functions and to have many different appearances, masses, and/or accessories. 
     SUMMARY 
     Embodiments include a fishing lure, having a head member with a quick-release mechanism to which a removable tail member attaches. 
     Embodiments further include different skirts that are capable of attachment to a removable tail member. Some skirts are formed tightly around a body and some skirts resemble tentacles. 
     Embodiments include a tail that is capable of releasing a drag chute when struck by a fish, capable of slowing the progress of a running fish, while facilitating reeling-in the fish. 
     Embodiments include dive wings, fastened to removable tails, capable of causing a lure to achieve a desired depth when pulled through water. 
     Embodiments for example those fashioned of 6061 aluminum and/or stainless steel, are environmentally sound, durable, and corrosion resistant. 
     Embodiments include a kit, comprising one or more heads with quick releases, tails, and skirts. In a “Swift Cast” lure system, lures can have adjustable weight, adjustable trolling and retrieving depth, exchangeable colors, and/or changeable form (physical size, shape and texture). Lures can also include built-in advanced swivels, built in controllable liquid chum (bait) delivery system, built in jets, built in turbulence inducing fins, and/or glowing capacity. 
     Various embodiments facilitate effective and efficient fishing in numerous applications (e.g., trolling, jogging, casting, sliding, bottom bouncing), and are capable of working in different rigging configurations (e.g., arm lure, teaser). Removable tails save time by providing quick disconnect and reconnect, only requiring seconds to change weight, color, form, and/or function on a single line, thus increasing fishing productivity. Space is saved because fewer units are required and many interchangeable components can be stored in one box. Consumers save money by replacing many single-use and/or single-function fishing devices with fewer components. Such lure kits are also versatile and fun for users; use being easily learned.

     DESCRIPTION 
       FIG. 2A  is a partially exploded view of an embodiment of a fishing lure, according to the present invention. In some embodiments, lure  200  includes head  300 , tail  400 , and skirt  700 . 
     In some embodiments, head  300  includes locking (quick release) mechanism  350 , operated by slide  330  on head shaft  303 . Tail  400  includes tail shaft  410 , which is formed with groove  412 . Shaft  410  inserts into receiver  312  of head shaft  303 , and groove  412  is locked by locking mechanism  350 . When slide  330  is pushed up on shaft  303 , groove  412 , and therefor tail  400 , is released by head  300 . Slide  330  may only release mechanism  350  if notches  314  are lined up with posts  316 . If slide  330  is rotated about axis  318  of head core  301  (as shown in  FIG. 2B ) so that notches  314  do not line up with posts  316 , then tail  400  cannot be released unintentionally. 
       FIG. 2B  is an assembled view of an embodiment of a fishing lure, according to the present invention. In some embodiments, skirt  700  includes shell  710 , secured on ring  720 . In some embodiments, shell  710  is a flexible material (e.g., rubber, vinyl, latex). Ring  720  is equipped with hole  722 , which fits over shaft  410  of tail  400 , and is secured between edge  424  of tail shaft  410  and edge  313  of head shaft  303 . 
     In some embodiments, shell  710  is not equipped with ring  720 . In some embodiments, shell  710  (or another type of skirt) is fastened to tail  400  with o-ring  790 , about groove  422  in tail  400 . In some embodiments, groove  422  is 0.087 inches wide, and is located approximately 0.50 inches from the start of tail surface  424 . In some embodiments, o-ring  790  is formed of black rubber with an inner diameter of 0.375 inches and an outer diameter of 0.594 inches. In some embodiments, skirt  710  is attached both to ring  720  and at groove  422  (with o-ring  790 ). 
       FIGS. 3A ,  3 A 1 , and  3 A 2  are side, end, and cut views of an embodiment of a lure head with a quick release mechanism, according to the present invention. In some embodiments, head  300  is approximately 1.825 inches long, and head core  301  is approximately 0.769 inches long and has a maximum diameter of approximately 0.560 inches. One end of head core  301  is roughly conical, at about a 15 degree half-angle, having a 0.140 inch radius blunt end at its peak and short (0.120 inch) cylindrical base  309 . The other end of head core  301  is cylindrical transition  305 , taking up approximately 0.312 inches of length, and having an outer diameter of 0.460 inches. 
     Head  300  includes hole  317 , approximately 0.125 inches in diameter, through transition  305 , 0.090 inches from edge of cylindrical base  309 . Pin  316  has a diameter of approximately 0.125 inches and is fixed in hole  317 . Pin  316  prevents motion of slide  330 , when it is desired to secure tail  400  in head  300 . 
     In some embodiments, hole  317  is through transition  305 , and one pin  316  is pushed through. In some embodiments two small pin  316  units are used. In some embodiments, two or more holes  317 , are formed at different locations around head core  301 , equipped with pins  316 , and notches  314  in slide  330  are formed to be capable of rotating to match their positions. In some embodiments, notches  314  are approximately 0.16 inches long and approximately 0.14 inches wide. In some embodiments, portions of pin  316  may be colored red (e.g., red anodize, red glaze), in order to given the appearance of eyes, thus making lure  200  more attractive to fish. 
     In some embodiments, head shaft  303  has an outer diameter of approximately 0.375 inches, an inner diameter of approximately 0.250 inches and a length of approximately 0.744 inches. In some embodiments, spring  340  has a diameter of approximately 0.390 inches and a free length of approximately 0.5 inches. In some embodiments, spring  340  is formed of SS  302 - 304  wire of 0.035 inch diameter. Spring  340  is placed around head shaft  303 , against surface  304  (at the end of transition  305 ), which has a diameter of approximately 0.46 inches, sufficient to retain spring  340 . 
     Head shaft  303  is provided with three countersunk holes  322 , transitioning from 0.110 inches to 0.078 inches (30 degrees), at even spacing (120 degrees) around head shaft  303 , approximately 0.24 inches from its end (surface  312 ). Bearings  324  are inserted in holes  322  (which retain bearings  324 ). In some embodiments, these dimensions are relaxed to improve functionality and to allow for easier assembly. For example, countersunk holes  322  may transition from 0.118 to 0.086 inches. In some embodiments, head core  301  may be ellipsoidal (or have another shape) instead of conical, to improve fishing in various conditions. 
     In some embodiments, head core  301 , transition  305 , and shaft  303  are formed of 6061-T6 aluminum. In some embodiments head core  301 , shaft  303 , and transition  305  are formed from one piece of material. In some embodiments head core  301 , transition  305 , and shaft  303  (or portions thereof) are finished with blue anodize. In some embodiments, the step between transition  305  and head core  301  is eliminated and both are changed to a diameter of 0.500 inches. It will a apparent to those skilled in the art that head core  301  can be formed of many materials (e.g., other aluminum alloys, stainless steel, other metals, ceramics, composites) and/or treated with other finishes (e.g., other colors of anodize, glazing, anodic coatings, bluing, glowing). 
     In some embodiments, slide  330  is 0.870 inches long, having surface  333 , grip portion  331  and lock portion  332 . Starting at grip portion  331 , slide  330  has a first inner diameter of 0.47 inches (over 0.532 inches), a second inner diameter of 0.400 inches (over 0.244 inches), and a third inner diameter of 0.43 inches (over 0.094 inches). In some embodiments, these dimensions are relaxed to improve functionality and to allow for easier assembly. For example, in some embodiments, slide  330  has first inner diameter of 0.48 inches, second inner diameter of 0.395 inches, and third inner diameter of 0.438 inches. 
     In some embodiments, grip portion  331  is 0.700 inches in diameter and 0.619 inches long, having a cylindrical portion 0.338 inches long, ending in a 15 degree conical taper ending in a truncated outer diameter of 0.546 inches, with a 0.030 inch rounded edge. 
     In some embodiments, lock portion  332  is 0.245 inches long with an outer diameter of 0.530, having its end is bezeled to 0.010 inches at 45 degrees. In some embodiments, the step between grip portion  331  and lock portion  332  may be eliminated and both changed to a diameter of 0.750 inches. In some embodiments, a 0.125 radius blunt at the end is added. 
     In some embodiments, slide  330  is formed of 6061-T6 aluminum alloy. In some embodiments slide  330  has a bright chrome finish. Of course, those skilled in the art will recognize that in some embodiments, slide  330  is formed from many other materials (e.g., stainless steel, other aluminum alloys, metals, ceramics, composites) and/or treated with many types of finishes (e.g., anodic coatings, bluing, glazes). 
     Slide  330  fits over head shaft  303  against spring  340 , and is retained by ring  342 . Ring  342  has and inner diameter of approximately 0.325 inches and outer diameter approximately 0.425 inches. In some embodiments, ring  342  is formed of SS  302 - 304 , of 0.050 inch diameter. Ring  342  seats in groove  320 , having a width of approximately 0.05 inches, an annular radius of approximately 0.025 inches (depth of 0.025 inches, width of 0.050 inches), provided in head shaft  303 , approximately 0.090 inches from surface  312 . Ring  342  is larger than second inner diameter  336  of slide  330 . Thus, slide  330  may move along head shaft  303 , confined by ring  342  and post(s)  316 . In its relaxed position, slide  330  is held against ring  342  by force of spring  340 . In some embodiments, posts  316  are formed of soft plastic or other materials and an additional inner edge in slide  330  is added to stop forward (non-relaxed) motion of slide  330  against surface  304 , rather than posts  316 . 
     When slide  330  is in its “relaxed” position, second inner diameter  336  of approximately 0.400 inches is positioned around balls  324 , forcing them into holes  322 . When slide  330  is moved against the force of spring  340 , and notches  314  slide around posts  316 , third inner diameter  334 , 0.430 inches (larger than second inner diameter  336 ), is positioned around balls  324 , allowing them to move outward from holes  322 , but not to escape from head  300 . Thus by action of slide  330 , balls  324  move radially with respect to head shaft  303 , freeing tail  400 . 
       FIG. 3B  is a plan view, from a rotated perspective, of an embodiment of a lure head core, according to the present invention.  FIG. 3B  is rotated 90 degrees from the view shown in  FIG. 3A . It can be seen that flange  326  of head core  301  is flat, and approximately 0.080 inches wide, containing hole  302  (of approximate diameter 0.125 inches), for tying on a line. Flange  326  is formed by cut-outs of radius approximately 0.313 inches, around hole  302 . These dimensions are provided as exemplary, and it is to be understood that hole  302  may be larger or smaller or shaped to accommodate a ring. In some embodiments an axial hole, through which a line may be tied, replaces hole  302 . Further, the area of flange  326  may be more flattened or curved or otherwise shaped to hold a ring or line in a given alignment and to introduce different swim patterns (“action”). 
     In some embodiments, head core  301  is equipped with one or more intake holes  327  and one or more jets  328 , so that when lure  200  is pulled through water, water and or air enters through intake  327  and exits through jets  328 . Thus turbulence may be caused around lure  200 , to attract fish to strike it. In some embodiments, there are two intake holes  327 , having diameters of approximately 0.125 inches, and three each jets  328 , having diameters of 0.063 inches. 
     It is to be understood by those skilled in the art, that given dimensions of head  300  and its parts are exemplary, and that head  300  may be scaled and/or re-proportioned for various fishing functions, environments, and purposes. For example, portions of head  300  could be made larger or smaller to make the overall mass of lure  200  increase or decrease, while leaving the inner dimensions of head shaft  303  constant, so it receives one size of tail shaft  410 . In some embodiments, head  300  may be more elliptically shaped and the step between head core  301  and transition  305  removed. It is also to be understood that in some embodiments, quick release mechanisms known to the art are adapted to perform the functions of mechanism  350 , while retaining the spirit of the invention. 
       FIG. 3C  is a cut line view of an embodiment of a head shaft and bearings, according to the present invention. A cross section of head shaft  303  is shown, with counter-sunk holes  322 . Holes  322  are formed with cone half-angle  323  of approximately 15 degrees. It can be seen that bearings  324  (for example 0.094 inch stainless steel balls) fit into holes  322 , but do not fall through them. However, a portion of each of bearings  324  is capable of protruding through holes  322  into a portion of receiver  312 . 
       FIG. 3D  is a partial sectional of an embodiment of a quick release mechanism, according to the present invention. Locking mechanism  350  is shown in its “open” (release) position and tail  400  is partly pulled out. Spring  340  is compressed between surface  304  of head transition  305  and surface  333  of slide  330 . Spring  340  applies force on slide  330 , keeping surface  335  pressed against ring  342  when locking mechanism  350  is “closed” (tail secured), as shown in  FIG. 3E . 
     When slide  330  is against ring  342 , surface  336  presses balls  324  radially inward to protrude through holes  322 . Balls  324  press into groove  412  of tail shaft  410 , thus retaining tail  400  in receiver  312  of head  300 . When it is desired to release tail  400 , slide  330  is moved away from ring  342 , bringing surface  334  over balls  324  and holes  322 . Balls  324  are free to move radially outward in holes  322 , freeing groove  412  of shaft  410 , thus freeing tail  400  from head  300 . 
       FIG. 3E  is a partial sectional view of an embodiment of a locking mechanism, rotated 90 degrees from  FIG. 3D , according to the present invention. Locking mechanism  350  is shown in its “closed” position and tail  400  is fully inserted. In some embodiments, two notches  314  are disposed 180 degrees apart around slide  330 . When slide  330  is rotated with respect to head  301 , around shaft  303  and transition  305 , notches  314  are aligned with posts  316 . When notches  314  are in line with posts  316 , slide  330  can move in direction  338 , unlocking mechanism  350 , and releasing tail shaft  410 . 
     In some embodiments, grip portion  331  is formed with scallops  339 . In some embodiments, 12 scallops  339  are positioned evenly around grip portion  331  at 30 degrees. Scallops  339  provide both a means of causing water turbulence and for providing a grip-able surface. Scallops  339  are cut with a radius of approximately 0.046 inches and extend for a length of approximately 0.510 inches along grip portion  331 , including a portion of the conical taper (approximately 0.172 inches). In some embodiments, a portion of slide  330  is roughened by sand or bead blasting, knurled, as by cutting a pattern in it, or machined by any number of methods known to the art, to achieve a grip-able surface. 
       FIG. 3F  is an end view of an embodiment of a slide, according to the present invention. Scallops  339  and surface  335  can be seen on slide  330 . 
     FIG.  4 A 1  is a plan view of an embodiment of a tail, according to the present invention. In some embodiments, tail  400  is approximately 2 inches long. Tail  400  includes shaft  410 , which is approximately 0.938 inches long and 0.240 inches in diameter (fitting inside receiver  312  of head  300 ) and tail core  420 , which is approximately 1.063 inches long and 0.375 inches in diameter. 
     In some embodiments, tail core  420  terminates in a truncated cone, having a 15-degree half-angle and an end rounded to a 0.140 inch radius. Tail flange  403  is formed in the rounded portion, being 0.080 inches thick, formed by 0.188 inch radius cuts on either side of flange  403  into the rounded end. Hole  402 , of approximate diameter 0.125 inches is through flange  403 . Hole  402  is capable of attachment to one or more hooks or a line to another lure. 
     In some embodiments tail shaft  410  includes groove  412 , which is approximately 0.067 inches wide, suitable for balls  324 , so that it will lock into locking mechanism  350  of head  300 . Groove  412  is 0.52 inches from the end of tail shaft  410  and 0.418 inches from the start of tail core  420  (surface  424 ). 
     Various embodiments of locking mechanism  350  may require different configurations of tail shaft  410 . It is to be understood that many quick release mechanisms known to the art could be adapted to various embodiments head  300 , requiring alteration to tail  400 , particularly shaft  410  and/or groove  412 . However, an advantage of mechanism  350  is that it allows tail  400  to rotate (swivel). 
     In some embodiments, tail  400  is equipped with scent chamber  430 . In some embodiments, scent chamber  430  is approximately 1.3 inches long and 0.093 inches in diameter. Scent chamber  430  is used to contain and release bait scents, for example squid oil. Scent (bait) is poured into scent chamber  430  through pour hole  431 . Tail  400  is equipped with one or more small release holes  434 , having diameter approximately 0.031 inches, so that scent trickles slowly out of chamber  430  into the water. In some embodiments release holes  434  are a pair of holed formed by drilling radially through tail  400 , and chamber  430 , 1.188 inches from pour hole  431 . Release holes  434  are small so that scent will release over a substantial period of time. 
     In some embodiments, pour hole  431  is sealed with plug  432 , formed from nylon. Plug  432  has a cylindrical portion 0.125 inches long and 0.093 inches in diameter, having a 0.010 inch bezel at 45 degrees, which fits in chamber  430 . Plug  432  has a head portion 0.031 inches thick and 0.208 inches in diameter to prevent it from getting stuck in chamber  430 . In some embodiments, chamber  430  has an internal thread and plug  432  is threaded. In some embodiments, plug  432  is formed of cork, rubber, or another compressible material. 
     Embodiments of given approximate dimension are exemplary, and it is to be understood that the dimensions and mass of tail  400  are adaptable to different configurations for different types of fishing. If a very long skirt is to be used, a longer version of tail  400  can be used. For tying on different skirts, edge  424  may be made larger or smaller or blunt radius may be added, and/or groove  422  can be reduced, enlarged, or omitted. Depending on the types of hooks or other attachments to be used with lure  200 , hole  402  and flange  403  can be increased or decreased in size. Various tails may differ not only in scale, but have different proportions. 
     FIGS.  4 A 2  and  4 A 3  are plan views of embodiments of tails, according to the present invention. FIGS.  4 A 2  and  4 A 3  are views of embodiments of tail  400 , in which tail core  420  is increased in size to a 2-inch length and a 3-inch length (and therefore also increased in mass) for different fishing applications. 
     In some embodiments, tail  400  is formed of aluminum. In some embodiments, it is anodized blue or otherwise treated to resist corrosion. In some embodiments, tail  400  is formed of other materials, such as stainless steel, ceramics, or composites, which may also resist corrosion. 
       FIG. 4B  is a cut view of an embodiment of a tail with a drag chute, according to the present invention. In some embodiments, tail  450  is equipped with releasable drag chute  500 . However, tail  450  has the same sized tail shaft  410  and groove  412  as tail  400 , allowing it to be used with the same head  300 . Chute  500  is formed of sturdy nylon or another rugged, outdoor-fabric, to resist degradation from ocean water and tearing from use. 
     In some embodiments, body  452  of tail  450  is elongated, to a length of approximately 6.94 inches to fit ribs  460 , which are approximately 4.69 inches long. Ribs  460  are outfitted with rivet holes  466  (approximately 0.078 inches) to which chute  500  attaches. 
     In some embodiments, pivot hole  463  (approximately 0.078 inches) of each rib  460  attaches to metal ring  482  (1-inch ID, being 0.063 inches thick, with a 0.125-inch gap), fastened around crown  480 , so that they may lay stored against tail body  452  then open to an angle of approximately 60 deg. Hook  462  of each rib  460  is held by o-ring  484  (1.125-inch ID; 1.313-inch OD), which provides radial tension toward crown  480 , forcing ribs  460  toward a semi-open “retrieving” position. 
     Rib  460  terminates in tab  464 , approximately 0.094 inches thick. Locking mechanism  470  includes inner surface  472 , having an inner diameter of approximately 1.187 inches. Inner surface  472  is capable of exerting a radial inward force on tabs  464  of ribs  460  against the force of o-ring  484 , so as to keep ribs  460  in a “trolling” (chute closed) position, parallel to tail body  452 . 
     Cap  474  (1.375-inch diameter, 1.313-inches long) of retainer  473  holds one end of spring  475  (approximately 0.875-inch free-length, 0.480-inch outer diameter, of 0.063 diameter SS), the other end of which presses against flange  454  of tail body  452 . Thus, when force of approximately 6 lbs. (the pull of fish  491 ) is applied to locking mechanism  470 , in direction  492 , locking mechanism  470  slides in direction  492 , freeing tabs  464 . This allows the force of o-ring  484  on hooks  462  of ribs  460  to open drag chute  500 . Thus, tail  450  with drag chute  500  can look like a lure before fish  491  is hooked, but open into a drag chute after fish  491  is hooked and tensile force on locking mechanism  470  (in direction  492 ) exceed approximately 6 lbs. 
       FIGS. 4C and 4D  are plan views illustrating an embodiment of a drag chute in use. Ribs  460  are released and chute  500  opens in direction  465  when fish  491  pulls line  493  through the water away from the user in direction  492 , providing maximum resistance (drag) when fish  491  is fighting. Also, ribs  460 , and thus chute  500 , will collapse in direction  485 , when pulled in direction  486  (reeling-in by the user), thus providing minimal resistance as fish  491  is reeled-in by reel  497 . 
       FIG. 4E  is an end view of a locking mechanism, according to the present invention. Locking mechanism  470  is equipped with vent holes  476  to reduce drag as tail  450  is pulled through the water, and to facilitate drainage of water when tail  450  is removed from the water. Grooves  478  (12 at 30-deg spacing, approximately 0.094 wide and 0.370 long) facilitate manual manipulation of release mechanism  470  and cause water turbulence. Holes  479  eliminate vacuums and facilitate drainage of retainer  473 . 
       FIG. 4F  is a cut view through an embodiment of a tail, according to the present invention. As with tail  400  (see FIG.  4 A 1 ), in some embodiments, bait chamber  430  of tail  450  is bored in extended tail shaft  452 , with fill hole  431  and deployment holes  434 . 
       FIG. 4G  is a partial assembly view of an embodiment of a tail drag chute, according to the present invention. Shaft  452 , spring  475 , locking mechanism  470 , and retainer  473  are shown in assembly position. Retainer  473  also has a drain hole  479 . 
       FIG. 4H  is a front view of an embodiment of a crown, according to the present invention. Crown  480  is equipped with slots  485 , into which ribs  460  assemble. Crown  480  is also equipped with drain holes  476 . Crown  480  has a central hole  486 , to receive tail shaft  410 . 
       FIG. 4J  is a cut view of an embodiment of a crown, according to the present invention. It can be seen that hook  462  of rib  460  stops against the bottom of slot  485  of crown  480 , limiting the maximum extent chute  500  can open (roughly 8-in in diameter). 
       FIGS. 4K and 4L  are illustrations of an embodiment of a tail assembly method, according to the present invention. Ribs  460  are inserted on metal ring  482 , through hole  463 . Ring  482  and ribs  460  are pressed on to crown  480 , and o-ring  484  is slipped over slots  485  and rib hooks  462 . 
       FIGS. 5A and 5B  are end and cut views of an embodiment of a drag chute, according to the present invention. Chute  500  includes sleeves  510 , inner hem  520 , and outer hem  530 . Ribbons  540  are attached around outer hem  530 . Sleeves  510  may run the length of chute  500 , or may be broken in segments  512 . 
       FIG. 5C  shows an embodiment of a drag chute assembled on ribs and crown, according to the present invention. Chute  500  is attached to ribs  460  by rivets  504 , through holes  466 . Ribs  460  run through sleeves  510  or segments  512 , thereof. 
       FIG. 6A  is a cut view of an embodiment of a drag chute release mechanism with adjustable release force, according to the present invention. Mechanism  600  provides for an adjustable compression force on spring  475 , to allow the user to set the tensile force at which chute  500  will be released. 
       FIG. 6B  is an end view of an embodiment of an adjustable release mechanism, according to the present invention. Adjustable release mechanism  600  is provided with vent holes  479  and grooves  478 . 
       FIG. 6C  is an assembly view of an embodiment of an adjustable release mechanism, according to the present invention. Housing  610  is provided with two sets of internal threads. Tensioner  620  (about 0.718-in max diameter, 2.125-in long, 0.500-in ID) threads into threads  612  (0.875-9 UNC-2B) of housing  610 . Spring  475  is placed with washers  630  inside tensioner  620 . Tail body  452  goes through spring  475  and washer  630 , tensioner  620 , and housing  610 . End piece  640  threads into threads  614  (1.000-12 UNF 2B) of housing  610 , and presses against flange  454  of tail body  452 . 
     By changing the position of tensioner  620  with respect to housing  610  (by screwing threads  622  in or out of threads  612 ), the amount of compression force on spring  475  is changed. Thus, different amounts of force are required to release mechanism  600 , depending on the adjustment of tensioner  620 . 
       FIG. 6D  is an end view of an embodiment of a tail body flange, according to the present invention. Flange  454  of tail body  452  is roughly triangular in shape, to allow water to pass by, reducing drag, and allowing the mechanism to drain when removed from the water. 
       FIGS. 6E and 6F  illustrate three tensions of an example release mechanism, according to the present invention.  FIG. 6E  shows adjustable release mechanism  600  in three different tension settings (although a continuum of tensions can be set). In some embodiments, tensioner  620  is provided with marks  624  (e.g., one, two, and three dots, “low-med-high”) to indicate the tension setting, which can be seen by the user. Undercut  626  facilitates cutting of thread  622 .  FIG. 6F  shows that release mechanism  600  changes length  650  from approximately 3.875 inches (low tension, approximately 8 lbs.) to 3.375 inches (high tension, approximately 24 lbs.). 
       FIG. 6G  is a side view of an embodiment of a release mechanism and tail body, according to the present invention. In some embodiments, two sides of tensioner  620  are flattened at area  642 , for example to a width of ⅝ inches, to allow a key (or other tool) to be used to help change tension. Grooves  478  facilitate gripping housing  610  during adjustment. 
     It is to be understood by those skilled in the art that embodiments are exemplary, and that many variations are possible.
