Left out of OB Thursday am and ran out to the Dumping Grounds to begin. We trolled the contour heading SW. Shortly after arriving at the east end of the Steps we came across some scattered grass where we picked up four decent size mahi. About two hours later I spotted a large frigate bird gliding up high. When I got over to it there was a pod of the small offshore porpoises working bait. I was in the process of making a circle around them when both outriggers, center rigger and port corner reels go off. It sounded like 22 rifles going off all at once. We ended up putting another decent mahi, one wahoo 74 lbs and another wahoo 62 lbs in the boat. Continued on towards the Petronius and trolled there until dark without any luck. Set up drift for Swords that night without any luck except a shark. Began trolling around Petronius again at crack of daylight then making way to the Marlin rig. As soon as we got close to the Marlin we hooked a nice Blue and had him on for about 30 minutes before the snap swivel straightened out causing us to loose him. Saw a whale breaching close to the Ram Powell but no fish. Had a ****** come up and eat every bait in our spread without getting a hook in her north of the Ram Powell. Beautiful cobalt blue water the entire trip with very little grass to deal with.
