The final shot!
B/T,
Hookem & I have gaffed sucesfully six threshers, the largest 600 the smallest 448. With the big fish, if you fight them right and do not take a shot at what I call the "Curiosity Appearence"(spoken about in early chats: the early appearence of the fish ) they will come up spent.
Once gaffed in the head with the boat motoring forward the fish will swim with the boat. What we like to do is we start pulling on the gaff line(s) and start to walk the fish up the side of the boat. Once along side, and the boat still boating we just drop the weighted tail rope around the fish. Once secured, we slack off on the gaff lines and the fish is now being towed backwares tail roped.
We have also found that their skin is much softer that the makos and it is easy to sink the gaff.
