My first sail

As long as I can remember, I have wanted to do a multi-day trip along the Georgia coast. I may finally have my chance. I hope to leave this Wednesday. I have a 24' Venture MacGregor with a 9.9 Yamaha. I have taken this boat out by myself twice.

I plan to sail by myself and leave Saint MArys GA and travel up the coast past Cumberland Island and Jekyl Island and cut in towards Brunswick and anchor for the night. Next morning to sail north to above Blackbeard island and anchor for the night. Friday I plan to sail home in one day if possible.

Questions:
1. What currents should I expect while going north and south up the ga coast? I plan to sail about 4-5 miles off the coast.
2. Will I be able to catch any fish trolling on my way?
3. Any hazards you are aware of?
4. Suggestions?

Thanks!
