Adding an AIS transponder to that kit would also be a great way to enhance safety - https://en.wikipedia.org/wiki/Automatic_identification_system https://en.wik

  AIS transmits much more frequently usually between 3 minutes and 2 seconds depending on speed. [0] AIS is also supplemental and basically every large vessel will have radar available that will spot these kinds of dead drifting ships. [0] Large 300 ton+ ships are type A: https://help.marinetraffic.com/hc/en-us/articles/217631867-How-often-do-the-positions-of-the-vessels-get-updated-on-MarineTraffic- https://help.marinetraffic.com/hc/en-us/articles/217631867-H...

    True ... but there are thousands of us that sail (sailed) small yachts which have a more limited range if they have radar at all (power consumption and antenna height cause certain restrictions). AIS on the other hand works great and also integrates with chart plotters for collision alarm with relatively small amounts of power. Small yacht sailors generally assume that cargo vessels will NOT try to avoid them, so having the ship continue on its (drifting) course wouldn't be too surprising.

      I had a small AIS transponder on my 30 foot boat. All smart and prudent skippers will have one now that the tech is so cheap.

      I realize I half finished my thought the main issue with adding AIS is the increased frequency increases power draw means you need a larger battery for this beacon. Either that or a solar panel which is more expensive and would get grimy over time and eventually fail.
