Twenty miles off La Jolla a private boater stopped on a big school of yellowfin up to 30lbs. The best action was fly-lining a sardine on 25lb fluoro and using #2 circle hook. Look for your own bird school away from the other boats to set up your drift. Shut your engines down and let them come to you. Don’t forget to throw chum and brail sardines to keep the tuna around the boat.
