[PUP] Arild and the design build "thing"

[Alan Wagner]

I was sitting here tonight talking with Debbie about my recent post  on our
design adventure and, in doing so, I realized that I would be horribly
remise not to mention our very own listee, Arild Jensen, who I got involved
after the Kasten design was nearly finished and right as were selecting a
builder.

Arild explored some alternative get home, electrical propulsion ideas I had
(that in the end were not practical), but in doing so I hired him to design
the electrical details of Passage of Time and he did a marvelous job.  It is
an often overlooked area that is most frequently left by the designer to the
builder.  Arild really focused me on the entire electrical setup, looked at
what I had put on my specifications list and made some hugely significant
suggestions in changing the refridge and air conditioning system components
for better energy usage.

In the end I think I ended up with a very elegant electrical design that I
am thoroughly delighted with and which is in many respects quite unique.
Thanks to Arild, I was able to scrap the third engine (the stand alone
generator).  My "get home" engine doubles as the generator, but delivers DC
power, not AC, to the batteries and the inverters via two huge alternators
(it's a 24v boat).  The John Deere main engine has an identical pair of big
alternators, so whenever the main is running the entire boat is fully
powered as if there was a generator running, but there isn't.  When the main
is running, for instance, the air conditioner is available if we want to
stay cool, without the need to start the generator (the wing).

Arild was a gold mine of help on an extremely important part of the design
and I hope that he forgives me in failing to mention him before this.
