After nearly tearing my rudder off, and nearly getting stuck on a sand bar going into west harbor, I decided the GPS chart plotter was a wise investment. Although you can see chanel markers ahead of you might not actually be in that channel. this holds true for around the islands. The channel markers around ballast island can be quite confusing without the chart plotter.
