Where to hang out ion Charleston, SC

[CharlestonSC]

Just got my new boat set and ready, now I need to know where to go. I have been cruising around the harbor. Been to Red's and California Dreaming (if you can get a spot to park). Where else is there to go? Someone told me about the mud flat out by Sumter being a good time on the weekends??? Any suggestions on when to go?

Thanks
