I finally broke down and bought a handheld radio to have in my pocket when messing around on shore in my dinghy. They are inexpensive, sound good, and nice for checking the weather if you have been on shore hiking for a few hours and feel it's time for an up date. I think the best choice is a floatable/waterproof unit, no better time for it to fall in the drink then when your in and out of the dinghy. The best reason for one is probably for that fateful day when you are watching your boat drag anchor from several miles away or if it sank while you were having a picnic or you fell overboard leaving your kids or panicked wife alone on board. The best story I heard; Some hunters watched from shore as an iceberg climb their anchor line, bow, and eventually the whole boat!
The reasons are many for having one. How many of you have them, back up for your main radio on your helm, or as your only one?
