Get a tablet and purchase the Aqua Map App. It's downloads Active Captain info which is live updates from participants as they go along the ICW. That info has saved me may times. Read this guys blog:

Bob cruises up and down the ICW every year in a deep draft sailboat and documents the entire trip. Look at the April posts when he came through Georgia. He also publishes a book every year on Amazon and makes updates on Active Captain.
I have made the ICW trip about a dozen times from Annapolis to Florida and beyond, usually piloting a 65' Flemming with a five foot draft. I prefer to run outside and bypass Georgia but have made the inside run as well. Aqua Maps also has tides and current data. You just have to time everything right and stay alert. Allow extra time so you are not pushing it. Some very cool places along the way.
