Hey,
I live in Savannah and was just scouting out the access to the beach because I am trying to get my 39 year old Hoble 16 operational again. It looked like access to the beach has not been blocked, but I asked someone who is renting chairs/umbrellas and she said she had not seen any sailboats there. We used to have an active sailing fleet number 294 but that was a long time ago. We used to always have at least a dozen at a time parked on the beach. The access point is about a block south of the curve just as you get close to the beaches. It is called 3rd street right next to the desoto beach hotel. Parking a trailer would be difficult there and the meter maids are very aggressive about writing tickets so you have to be legally parked at all times. Anyhow, even if you can not get to the beach at Tybee is is worth driving down to St Simons Island in Brunswick. They have an excellent launching location with free parking and facilities. Sailing is good at either location. On Tybee I have never sailed in the back river although I know others have successfully from there. I feel like launching through surf might be risky but in the right weather I suppose you would be able to go into the ocean without too much trouble, I would not advise sailing north toward Hilton Head. The shipping channel is very busy and you would not want to cross it unless you had good speed. I saw someone ride the bow wave off a ship and I thought he was on the other side of the ship. Scary. Go too far to the south and you can hit sand bars but if you head straight out and back it is a good ride. Same probably goes for St Simons Island. I was about 2 miles offshore around 1984 there and hit the largest wave I have ever seen - about 12 ft and my boat went completely airborne but usually we only have about 4 to 6 ft swells when windy. Anyhow, post a reply to let me know when you are headed down. I will try to get more info about launch conditions here. One thing that always worked against us is that the department of natural resources kicked us out of the sand dunes because they wanted to protect the beach plant and wildlife. So it is not quite as sailboat friendly as it was in 1982 when I got my boat. Pull up the google satellite maps and look for 3rd St on Tybee, or on St Simons look for East Beach and you will see a parking area there with about 50 sailboats. Also st simons has a web site with more info
