Next winter I'm hoping to keep my Catalina 22 in a slip in Titusville and sail on the Indian River there. Some of the charts show the water as quite shallow. The boat is a swing keel so draw is about 2 feet with the keel up. Has anyone sailed this area? Advice? Also is there a source for navigational maps? I've just been looking at the small maps on Google. Or is there an app for my iPad or iPhone?
