While visiting George in the winter of 1978-79, I had
the opportunity to review this submersible and meet the two gentlemen for whom
it was commissioned. The sub was purpose built with a lengthened,
flanged hull sealed with a rubber gasket and numerous bolts to aid in
maintenance of the diesel. The sub was headed to Alaska for commercial
and salvage work. As there was much ice out on the local waterways, the
owners were able to practice submersible ops with a K-250 in a large tank next
to George?s sub construction barn. I also was able to play in the K-250
towards the end of the day. I received no instruction at all, George
figured since I had spent time on subs that I would be safe (almost did not
make it up on my last surfacing effort as the scuba tanks were running dry
J). Crashed with the owners
at a motel in Rocklin where we consumed a fair amount of beer swapping sub
stories.
A few years later, met up with the sub owners once
again. While they wouldn?t speak poorly of their expensive investment,
there were issues with extreme noise, exhaust fumes, and diesel fumes that
made operating the sub to its fullest capabilities impossible. Shortly
after the sub was listed for sale and must not have sold readily as the ads
were listed for quite some time. Seems to me the asking price was
$450K. Believe it was finally sold but don?t know for how
much.
While I would love to have a sub like this have
learned that it isn?t really practical in the typical PSUB. Reading
operational accounts of some of the early Nordenfeld (SP?), Holland, and others
along with the Japanese small submersibles leads me to believe it takes a
larger sub to safely mount a diesel. Even the X-craft had many troubles
related to diesels in their small confines.

[PSUBS-MAILIST] newbie questions
I've heard George cut the hull towards the stern and
put flanges on each
of the two parts to bolt it together, but I have no
idea if he had to
lengthen it -- in a photo it looks the same as a
normal K-350. He had a
snorkel that looks about 3-4 feet tall behind the
coning tower. The
snorkel had a poppet valve at the top to shut it off
upon submerging,
but also of course a hull stop on the inside. The
snorkel was not piped
to the engine, it simply allowed air into the cabin
and the diesel took
air from the cabin atmosphere. Cooling was via sea
water. Exhaust was
into the water. Transmission via a standard marine
gearbox with forward
and reverse. I have only seen a photo, and spoken to
George about it
briefly, so that's the sum total of what I know about
the diesel
electric K-350. Do we have anyone on the list who has
actually seen it
in person?
Thanks,
Alec
