I got my boat (21' wellcraft CC) now where can I go and what do I use to catch some kings and Dolphin? I dont want to go too far out. Maybe put in at Freeport. What do yall think?

We run from GYB and catch plenty of kings within 15 miles. Saw plenty of dolphin within that this year too but the water has to get pretty blue for them to get in that close. Any rigs or underwater structure should hold kings. Had best luck free lining sardines or trolling. The dolphin liked casted jigs in pink or chartreuse
