A VHF icom marine radio, for instance, should be equipped on your boat should the need ever arise for you to get a hold of someone during an emergency. VHF icom marine radios are equipped with Digital Selective Calling (DSC), so it will be very easy to you to call the Coast Guard or other boaters close to your area. You can either have a traditional VHF radio installed on your boat, or buy a handheld one. It's totally up to you, all that matters is that you have some way of getting a hold of help in times of distress.

The Chesapeake Bay has a muddy bottom almost everywhere, and so do the tributaries draining into it, which makes them a stubborn enemy for a keel-boat but forgiving none-the-less.
