Cortez and Tanner Banks this year so far = small tuna, nice grade yellowtail & pesky skipjack, been there on 2 open party trips, 1.5 days & 2.5 days. Your best bet for the 100+ lb bluefin tuna is the west side of San Clemente Island. I personally witnessed a 210ish lb Bluefin hit the deck on the 2.5 day west of SCL on a 250g glow flat fall fished in the dark about 4-5am in the morning. All 32 on board had their glowing flat fall jigs in the water on our one and only drop and 2 lucky anglers hooked up, not me = ( , one spat the hook & the other brut was subdued in 20-25 mins on 100lb test on a 2 speed 50 size reel & meat stick. After that 1st & last drop Captain Kirk wanted to go chase the small yellowfin tuna, so we left the west side of SCL to go chase little tuna & skipjack on the lower banks, I was less than happy with the decision, but hey most on board were not properly equipped for the job, so can't blame Captain.
