The waters comprising the Lantana Anchorage lie just south of the Lantana Bridge (itself just south of West Palm Beach), and off the AICW’s western flank. Protection is only fair here, and, as Captain Sterling notes below, you are subject to the wake of passing vessels.
Good holding, but you may get some wakes. However, the tiki bar on shore is worthwhile, with wifi, and good happy hours. Walk to town (one block) for library, drug store, restaurants.
