I was just thinking the other day about how quickly technology(particularly
in the various communication areas) has evolved over the past 50, 20 and
even 10 years, primarily due to the conversion to digital systems ... and I
am not referring simply to computers. HD TV, HD radio (even AM), DVD, CD,
cell phones, GPS, .... the list goes on and on.

And, as fiberoptic lines expand and replace cable lines, the digital age
will grow even more.

It's all going to come to an evil end. You heard it here first. The
more digital we become, the more compressed the infrastructure which
means that if there is a major event at one or two switch points, the
potential for a cascade which shuts down the whole system increases.

And it also means that the ability to control what one can access
becomes easier.

Why would you want duplex?

Uh? He likes to talk while the other party is talking?

There is nothing wrong with simplex operation - you just need to keep
your conversations to a minimum and short.

This whole thing about duplex is silly - duplex doesn't give you any
advantage at all and besides - technically, VHF isn't for conversation
- theoritically.

ROTFL!!!

Fiber has it's places, short runs in a boat ain't one of them. The
vibrations in a boat would be problematic. Not to mention the higher costs
of terminating fiber cabling. On a larger vessel it might be worth
considering, but unlikely on recreational vessels.

I'd still lke to know why you think duplex is so important.

Try talking to my wife on a semi-duplex cell phone someday and you will
understand.

Given the crowded nature of the airwaves it would probably be BETTER to not
have full-duplex. If folks feel the need to prattle on endlessly let them
use cell or satellite phones... and PAY FOR IT. Stay off the VHF for that.

We already have ethernet and a few variants on recreational boats.
It's only a small jump from there to fiber optic networking. Some big
advantages are no connector corrosion issues and no induced noise, not
to mention high bandwidth for things like multiplexing radar displays
and such.

With three engines there is a good chance of keeping the boat running
on plane if there's a failure, not usually true with two engines

Not to mention that triples look WAY cool.
