Unfortunately, the Powerstream units output 13.8 v not 12, or do they have
one that I didn't see?

 Here is an off the shelf 270W PS that I am going to use to feed a
 regulated 12VDC bus in the nav station:

  I am trying to get a design for a 12 volt DC to 12 volt DC regulated
power
  supply. The design is to provide 12 volts DC + or - 5% output from an
input
  of between 8 volts and 16 volts DC.
  The purpose of this is to run a computer in a sail boat. The battery
voltage
  in the boat may vary from 8 volts to 16 volts when it is charging.
 
  I currently have an ATX computer power supply that runs off 12 volts DC,
it
  provides 3 and 5 volts nicely, but the 12 volt rail is actually the
input
  voltage. So, when the input is 12 volts all is well, if it goes high,
well
  that could be a real problem, and if it goes low, the computer will shut
  down. If you can help it would be much appreciated
