Offshore Wrecks- Where?

My Grandpa's bringing up his sailboat from Florida in Summer. Anyone know some good offshore spots to fish? I want to target Seabass, Cobias, Piked Dogfish, and Triggers, as well as anything else that's around. Now I'm no navigator, but my Grandpa has a GPS and everything so if you give me coordinance or something I can tell him and he'll find it for us. Preferably the spot should be less than 100 feet deep as I'm not in the mood for experimenting on venting a fish. Also I would like a deadbait r artificial lure tactic to use, as well as line wieght. Thanx,
