I was reading the rescue stories on my starboard side bar this morning and there was one where a guy was thrown into the water and his boat sank. He had his phone in a waterproof case and was able to contact the rescue folks from the water and get help. I had never thought of that. We have a portable VHF in a waterproof case down below. That won't help me if the boom knocks me in the water while I am single handing. I plan to get a waterproof case for my iPhone, how about you? Most of us have phones in our pocket when we sail and this makes a ton of sense. No case, no phone usage once you are overboard!
