"One of the truly most difficult and rewarding feats in fly fishing is catching a billfish, and the most impressive billfish to catch is a blue marlin. There seems to be an infinite number of ways to lose a blue on a fly, but one technique I call the “Charlie Tuna” will at least get you more bites. If you have ever fished for blues using fly, you'll know that even a well teased blue marlin can somehow not see or not care about the fly and make that infamous sweeping turn way outside the hook up area, just to finally lose interest and never come back. What "Charlie" does is not only bring him back, but bring him to where you want him. I got the idea more than 15 years ago when I was staring at one of those fish mount scenes where the blue marlin is chasing a school of tuna. About 12 years ago, I had Grey's Taxidermy send me a couple of double sided 12-inch bonita mounts that we rigged up as teasers. They are light and float high on the water, which makes them perfect for this application. Once a blue marlin comes racing in on a teaser, fails to bite the fly and swims off, you cast the "Charlie" that is attached to a spinning rod past the area of the fish and start retrieving it. Once the marlin sees this teaser he will most likely try and crush it with lightning speed, so be prepared to wind your butt off. Once you have the marlin in pursuit, bring the "Charlie" right by the fly and as you pass it, the angler strip-pops the fly and you flick "Charlie" into the boat. By this time the boat has long come to a complete stop, so the strip pop is essential and usually just one to two jabs does the trick. Half the time the fish will inhale the fly right off the bat, but even if the marlin continues to swim forward looking for "Charlie" under and around the boat, he's now seen your fly and knows where it is because of those pops you made as he swam by. It's not an exact science, but we have upped our hook up ratio tremendously using this little fiberglass tuna. Made of fiberglass you can pull it fast, because it's light. The guys at King Sailfish Mounts made the one you see here with an eyelet already glassed in."
