Only "Party" boats I have been on that area are up in Tampa at Madeira Beach(Hubbards Marina) there are some boats that specialize in long trips far offshore. There they have livewells sectioned off so you can rent a slot & get 1-2 dozen pinfish(Saltwater Sunny) & fish way offshore with live bait for Grouper, Amberjack etc ? Went on one of the 8-10 hr trips few years ago & was catching Amberjack in 80-100 ft of water & you could see the fish like 50-60 ft down in the water.
