Weems & Plath introduced a new safety device at the U.S. Sailboat Show in Annapolis. I think it is pretty creative as it uses Bluetooth connectivity to link a smartphone to a wearable transponder. If the signal is lost, or the unit is immersed in water, the smartphone sounds the alarm with sound, strobe, and vibration.
It is a new application of Internet of Things (IoT) connectivity.
Carrying an Air Band VHF radio on your next passage might be of value if you need to call for help. Even at high altitude, it is possible to communicate with a passing aircraft to get the word out that you have an emergency and need help.
If you are doing the Loop, ICW, northern canals, or other waterway cruises that involves narrow rivers or canals, reacquaint yourself with the proper signals for passing other boats and marine traffic.
When you dream of the perfect boat for all the cruising dreams you want to do now, stop thinking you need a battleship. Take a chill pill and read about a couple who went way beyond the cruising plans of most anyone wanting to liveaboard and see the world.
