I don't think it would be feasible to transmit WiFi WiMax or Cellular 
signals through the hull of a sinking ship.

Ultrasonic, maybe.  I don't know how well the signal would maintain 
integrity with machinery going berserk all around.  I've experimented 
with infrasound in the past, but it's easier for sounding than for 
signal transmission.
