I've never fished in Savannah, but we do go to Jekyll a few times a year to do some shark fishing from the beach. Word is they caught a tiger off St. Simons (I believe) just a few weeks ago, so the sharks are out there and eating. The biggest thing with how we fish is you need some big reels, big baits and a kayak to set the baits out in the surf.
If you are just looking to catch a few fish, I bet you can do just that by tossing some squid out on the bottom. That always seems to get eaten out there. But, for the big sharks, we use whole bonita or a whole sting ray. I am not super knowledgeable about surf fishing, but can usually fake my way through it. If you have any questions, I'll try my best to answer them.
Here are a few threads about some of our trips:http://www.georgiafishingforum.com/ubbthreads.php/topics/9135/Jekyll_Shark_Fishing#Post9135http://www.georgiafishingforum.com/ubbthreads.php/topics/10323/Re_Jekyll_Island_and_Mexico_Behttp://www.georgiafishingforum.com/ubbthreads.php/topics/13461/Jekyll_Island_and_Mexico_Beach
