I've been approached on several occasions by motorboat friends and acquaintances who were about to take an extended trip on their vessel. I always ask them if they have a radio onboard, and the answer is almost always "no." When they inevitably ask me why they should have one, I simply tell them: "To communicate your peril."
I used to do a lot of backcountry skiing in the Rockies and I took an avalanche course one time. When we did "peep" practice (transponders) the instructor gave us some sobering advice - "The purpose of the peeps is not to make it safe to ski in an avalanche prone area. It's to save time so your friends won't get hypothermia while they are looking for your body."
