The present invention is in the technical field of fishing gaffs. More particularly, the present invention is in the technical field of flying fishing gaffs.
The present invention relates generally to existing flying gaffs used to stab and subdue large fish.
A gaff is a Pole that has a sharp hook on the end of a U-shaped steel rod that is used to stab a large game fish and then lift the fish into the boat or onto shore. A gaff is essentially a large fish hook that is permanently attached to the end of a long Pole. Like a fish hook, the gaff consists of a steel rod, called a Shank, that is bent in a U-shape so that the Bend causes the bent end of the Shank to parallel the Shank in the opposite direction. This parallel Shank is typically about half the length of the Shank before the Bend. A sharp point is located at the end of the bent section of the Shank. This point is used to stab the fish. As with a fishhook, the entire length of the steel rod is referred to as the “Shank”, the Bend is called the “Bend”, and the point is called the “Point”. The space between the two sides of the bent Shank caused by the Bend is called the “Gap”.
Gaffs are used when the weight of the fish exceeds the breaking point of the fishing line or the fishing Pole. Because of the damage caused to the fish by being stabbed by the point, existing gaffs cannot be used if it is intended to release the fish unharmed after capture.
Gaffs are made in various sizes (diameter and length of Pole and Shank, size of Gap, etc.). Poles are typically made of wood or fiberglass, or various space-age materials and Shanks are made of various grades of steel.
A “flying gaff' is a specialized type of gaff used for securing and controlling very large game fish. The shanks on flying gaffs are not permanently attached to the Pole but fit into an opening on the end of the Pole which is designed to release the Shank when the Shank is pulled upon. On existing flying gaffs, a steel ring is typically welded to the Shank a short distance up from where the Shank is connected to the Pole. A rope is then attached to the ring by a snap hook attached to one end of the rope. The rope is made long enough to ensure that there is sufficient scope to both stab the fish and hold on to it as it tries to escape. To ensure that the rope does not interfere with the crew, the rope is typically run down the length of the Pole and attached to the Pole with attachments such as zip-ties, rubber bands, light tape or a cam cleat. The open end of the rope is then attached to a cleat on the boat. Once a fish has been stabbed by a crewman and pressure is applied to the Shank by either the fish or the crewman, the Shank will pull free (”fly“) from the Pole, the rope will pull free of its attachment to the Pole, and the Shank will remain hooked into the fish. The crewman will then toss the Pole out of the way and grab the rope to secure the fish. Because the end of the rope is attached to a cleat, in the event the crewman loses his grip on the rope the fish will not be able to escape because the rope remains secured to the boat's cleat.
The use of gaffs and flying gaffs to subdue and control large game fish from a boat at sea is the single most dangerous practice in game fishing. Slack ropes, detachable Poles, steel gaff heads, thrashing fish, rough seas and boats moving forward or backward (”backing down“) while fighting a fish can combine to cause serious injury or death to crewmen.
In addition to using gaffs to subdue and capture large game fish, boat crews often try to lasso the fish's tail with a stout rope since the power of a game fish and its ability to escape is primarily in its tail. When brought alongside a boat by a fisherman, the fish's tail is typically thrashing about wildly. If a crewman can place a stout rope over the fish's tail (lasso the tail) the battle is essentially over. Doing so, however, can be extremely difficult and dangerous. To do so a crewman might have to lean over the boat's gunwale, lean down toward the surface of the water, and try to wrap the rope over a thrashing, forked tail that might be over three (3) feet from tip to tip, all while trying to maintain his balance and position in the boat while rough seas and the boat's motion are bouncing him up and down and splashing waves of water against his face and body.
The present invention has been designed to both replace existing flying gaffs when it is the intent of the fisherman to release rather than kill a fish that has been brought to the side of a boat, as well as to provide a safe method of grasping and holding onto the tail of the fish without exposing crewmen to the dangers they presently encounter when lassoing a game fish's tail.
The present invention is designed to permit large game fish, including marlin, swordfish, sharks and tunas to be subdued in a fashion similar to that used by gaffs and flying gaffs, but without causing serious injury to the fish, so the fish can be easily subdued, measured and, if desired, released to swim away and survive. This is known in recreational fishing as “catch and release”.
Catch and release is a practice within recreational fishing intended as a technique of conservation where fish that have been hooked and brought to the side of a boat can be examined, measured, unhooked and returned to the water relatively unharmed. This practice has been growing exponentially in recreational fishing circles all over the world.
The present invention is similar to a flying gaff in that it incorporates: a Pole; a Shank that attaches to and can be pulled free of a Pole; a Bend in the Shank; and a steel ring to which a Rope is attached. It does not, however, contain a point at the end of the Shank which is instead rounded off. In place of a point to stab a fish, the invention uses two steel bars, actuated by Helical Torsion Springs, that are attached to either side of the Shank and across the Gap. These bars act as a one-way double gate that springs open and then closes when pushed or pulled across the narrow part of the fish's body (the caudal peduncle) to which the tail attaches, thereby making it impossible for the fish to pull its forked tail free from the space between the closed gate and the Bend in the Shank.

The present invention has been designed as a tool through which a fisherman can catch, subdue and then release a fish that has been brought to the side of a boat in a way that prevents serious injury or death to both the fish and crewmen on the boat.
The present invention also provides a safe method of grasping and holding onto the tail of a large game fish without exposing crewmen to the dangers they presently encounter when lassoing a game fish's tail.
The invention consists of:
(a) a Pole of from six (6) feet to ten (10) feet in length (No. 1 in Photos 1 and 7);
(b) a round, hollow, steel, Quick Release Snap fitting that is secured to the end of the Pole (No. 2 in Photos 1 and 7);
(c) a steel rod or “Shank” containing a Bend in the Shank that turns the end of the Shank in a one hundred and eighty degree) (180° direction (No. 3 in Photos 1, 2, 4, 5 and 7), the long end of which contains two (2) machined slots into which two O-Rings have been inserted which permit the Shank to be inserted snugly into the Quick Release Snap Fitting and later pulled free by exerting pressure against the Pole. (No. 4 in Photos 2, 4, 5 and);
(d) a Steel Ring, welded to the Shank (No. 5 in Photos 1, 2, 4, 5, 6 and 7), to which a Rope (No. 6 in Photos 1 and 6) is attached by way of a Locking Carabiner or similar clip (No. 7 in Photos 1 and 6);
(e) two (2) steel bars called “Capture Gates” (No. 8 in Photos 1, 2, 4, 5, 6 and 7), actuated by two (2) Helical Torsion Springs (No. 9 in Photo 3), showing a single torsion spring), are bolted to each side of the Shank using common bolts, locknuts and washers (No. 10 in Photos 1, 2, 3, 4, 5 and 7).
The Capture Gates cross the Gap formed by the bent Shank (No. 11 in Photos 1, 2, 4, 5 and 7). At the point where each of the Capture Gates are attached the Shank the Shank has been machined-out and drilled-out to hold each Helical Torsion Spring, as well as the bolts that attach the Capture Gates and the Helical Torsion Springs to the Shank (No. 12 in Photos 3 and 5).
The Helical Torsion Springs (No. 9 in Photo 3) are held in place by the nuts and bolts (No. 10 in Photos 1, 2, 3, 4, 5 and 7). Their action as springs is controlled by positioning one end of each spring against the inside wall of the machined-out Shank and the other end against the inside bottom of the Capture Gates (No. 13 in Photo 3).
The Capture Gates consist of two U-Channel bars that have been machined and positioned on the Shank in such a way as to permit the open sides of each U-Channel bar to fit around the width of the Shank when the Capture Gates are in a fully open position (No. 14 in Photo 5).
The outer end of the bottom of each U-Channel bar has been cut away to a length that permits each capture gate to be bolted to each side of the Shank (No. 12 in Photos 3 and 5), so they are capable of springing open (see partially open gates, No. 8 in Photo 4), but yet stopping in a closed position, when they are perpendicular to and across the Gap when the Capture Gates are in the fully closed position (No. 8 in Photos 1, 2, 6, and 7).
The Capture Gates are designed and bolted in place so as to permit them to spring open toward the Bend in the Shank when the Capture Gates are pulled across the narrow part of the fish's body to which the tail (the caudal peduncle) attaches (No. 15 in Photo 6).
When attempting to capture a fish the crewman positions the invention with the Gap end of the invention just past the fish's caudal peduncle. At the appropriate moment, the Pole is then pulled toward the crewman which causes the caudal peduncle to push open and move past the Capture Gates. Once the caudal peduncle passes the Capture Gates the Helical Torsion Springs on the Capture Gates cause the Capture Gates to spring closed in a position perpendicular to the Gap. As a result, the fish's tail is trapped between the closed Capture Gates and the Bend in the Shank (the “Capture Space”) (No. 16 in Photo 6), making it impossible for the fish to pull its forked tail (No. 17 in Photo 6) free of the invention. The pulling action on the Pole by the crewman, as well as the thrashing of the fish's tail, will cause both the Shank and the rope to pull free from the Pole. The crewman can then throw the Pole aside and grasp the rope to hold onto the fish.
