[PUP] Distributed Power Systems

[John Blair]

I have recently read of a new approach to power distribution on boats.  This
new 3-wire power distribution system uses significantly less copper wire
and can be used on boats as small as 18 ft. or, for example, up to maybe the
QE2.



My question is: does anyone have any current experience with or has read
reports on the cost affectivity of this approach for either new builds or
retro-fits?  From the descriptions I have read, it seems to be relatively
simple to install and maintain, although I suspect a near or direct
lightning strike could be devastating, unless there are some pretty heavy
duty surge protectors installed.  Maybe even this would not be enough. I
could not find any information on cost effectiveness. Maybe the technology
is too new.



Any information would be appreciated.



Thanks,



John
