I have this addiction in common with most on this board.......the search for tuna. Specifically yellowfin tuna. The closest possible location to catch these seems to be the Bahamas, although some big YFT have been known to "get lost" just offshore of Miami. I know little about fishing, and my crew knew less. Last saturday June 6th i went to Bimini with my fiancee and she indulged me by going to the Isaacs en route. Seas were calm when we left Miami but grew to 2-4's following seas once halfway thru the gulfstream. A quick USCG stop and we continued. Once we reached and passed the Isaacs i was able to land 2 large bonito on a double hook up under some bird activity. She grew tired so we headed to Bimini to the hotel. The following seas mutated into a stiff confused 3-4ft chop which pounded me on the way in. She had the beanbag chair. The seas laid down to smooth for the return trip to Miami on Sunday. Struck by failure to catch my first YFT, i watched the weather report. Seas were forecast to continue to be glassy smooth. I had 3 volunteers come along for a quick wednesday return trip. Recent purchases to prepare for the return trip included a 6'6" 20-50lb Saragosa rod, a Saragosa 18000F with 80lb JB hollow attached by a uniknot to about 6-8ft of Momoi 80lb fluoro. A Yozuri hydropopper was the casting lure. After some bottom fishing, 4pm came around and it was time to hunt for YFT. Bird flocks from the Isaacs materialized on cue and we quickly located some fish, but not sure what kind. I tried trolling waaaaay back but the schools and birds were zigzagging everywhere. Since i know not to troll over the fish, it was difficult to determine how to get ahead of them. I then tried chunking, but the chunks took forever to get any depth, and that plan was quickly changed back to trolling and maneuvering the boat in front of the running schools. Finally we were able to hear the drag sing, but 5-10lb skippies were the results. No YFT. So my addiction worsens.....questions.....if the seas are glassy smooth, do the tuna not bite? I could only cast maybe 20-30 yards with no downwind to help me.....was it the rod or the 80lb JB hollow line? Are Bimini twists with large snap swivels attached to lures visible to fish? I used cedar plugs, some "Draggin Eyes", and another plug called a "Pelagic plug from Bigbite offshore. My chunking was a dismal failure......any tips appreciated.
