Really what you're going to feel most ten miles out is the effects of the Gulf Stream. usually in that area there's a back eddy that runs south along the coast, but there can also be a back eddy on the back eddy as you get farther and nearer. And it depends a lot on what the breeze has been doing over the past week or two. In and out of Port Royal Sound you will find it can be very rough when wind and tide are opposite. Take a look at the Gulf Stream section for your area on passageweather.comand you'll get an idea of what to expect of the currents. In the long run they are pretty negligable usually.
