I'm no expert on that lake but I'd fish the docks and grass beds in a little deeper water, if you're bass fishing. I'd imagine the White Perch bite is heating up, and this should be visible if you see a ton of boats towards the middle of the lake trolling.
Lake Waccamaw holds some of the biggest fish for multiple species, but you have to put A LOT of time in there before you'll consistently catch them. Good luck, and regardless of how big your boat is, if it gets windy get the heck off of that lake.
