That is a great list for starters, Bob!
I have one small suggestion regarding the EPIRB or PLB. I have an epirb, but only take it if I am doing a solo, multiday camp/sailing trip--like soloing along the coast of the Everglades in FL.
My epirb/plb substitute is the much more useful SPOT (http://www.findmespot.com/en/
) My SPOT, now 2 yrs old, goes with me everywhere--sailing, kayaking, road trips, trips to Mexico and China, etc. I use it to send "I'm OK" messages from my AI, from the dash of my car in Yellowstone Nat'l Park, travelling down the Yangtze River on a cruise, etc. The "OK" messages go to my wife (she is often with me), children, some relatives, and a few friends. These "OK" messages have been close to 100% successful. I've never had to use the "911" message (sent when you are in a life-threatening situation,) but people have used it with good success. You do need to buy an annual subscription from the SPOT people--$100/yr, I believe.
There are traditionalists that insist an epirb/plb is the only way to go. That is their choice. For me, my SPOT has been a terrific device.
