Hi slab, The Whitebreast area is probably the most popular area for crappie on the lake during the spawn and early spring but don't overlook the other woody coves. A 16' jon boat should work fine as long as the wind isn't blowing things up too much. Best time in the spring can vary from the middle of may to the middle of june depending on the weather. Once the water temp reachs around 60 they'll be movin to the shallows during the wamer days. Use your sonar to find structure and you should be able to catch some now. You can't go wrong with a slip bobber and a minnow and as far a jig color....use the color you have most confidence in. Good Luck
