Wifey B: Fall off the bow of your boat into icy cold water, (shivering from the thought) and an inflatable may very well save your life and allow someone to assist you out. Out fishing alone, and you're one of those peeing over the side types, you better have one on. Many struggle getting back in a boat after an unplanned dip. Those are things inflatables are good for. Cruising in rough seas, not.
