Headed outside Kaneohe Marine Base trolled the 400' ledge just outside the 3 sonobouys. After trolling 20+ times and just catching Aku's and Kawakawa'a, finally heard our Penn 80's going off. Took a double strike of Ono's. After bringing in both to the swivel, decided to Gaff the smaller one on the mono leader and let the other one on steel leader do figure eights under the boat. After gaffing, konking it on the head, and dragging it on board; started lifting the second one to gaff, just as it finished gnawing through the coffee colored stranded steel leader. Sadly stood there watching the Ono slowly swim off and my lure sinking to the bottom of the ocean. Oh well, God blessed us with one hell of an experience. No one got hurt, and we still came home with a great 38 lb Ono. Thank you to every one who posts on this site. I've learned lots by reading your posts and your pictures inspire us to keep on going out there and try. To any other "rookie trollers" such as myself. We were trolling at 7.2 knots. 6 poles out, 2 on downriggers just off the back of the boat, 2 on the surface, just where the prop wash was almost gone, and 2 way back about 150'. We always catch the Aku's and Kawakawa's way back on small 4" lures. Both Ono hit the middle surface lures. the one that got gnawed off was a marlin magic slant head 7". Top skirt was black on top, red strip down the middle and purple on the bottom. Under skirt was orange on top and white on the bottom. In hindsight, 6 poles were too many poles for us to handle in the excitement of the double strike. We had a ridiculous tangle of down weight lines, 4 other lures, leaders, and hooks after we got the fish on board. Should we have left the second fish out there with out reeling up to the boat while we concentrated on the first fish? I wouldn't have known what it was till I brought it up to the swivel I had the boat in neutral so the prop wouldn't tangle in the mess of lines. If we had another person on board we might have been able to keep the boat in gear and lines out of the prop. Any suggestions on next time?
