    Paul-
     < I guess they are not worried about secure
    comms from another vessel.>
     More likely they've just realized that semaphor and lamps are slower, require 
    more training, and are less secure than an ordinary crew member using a 
    secure spread spectrum hand radio, or a direct laser "radio" link. If you can 
    use an FRS radio or point a flashlight, you can use secure high speed 
    communications these days. It is probably cheaper to buy a couple of hundred 
    secure radios, than to train one signalman. That's cost effective.
