[PSUBS-MAILIST] dive report Gamma

Sun Jul 26 17:28:52 EDT 2015

Thanks, guys.

The video files are large with a lot of useless footage.  I will try to put together a mini-compilation of the good stuff and have it up on YouTube.

Alan, we surfaced right under the dive safety float.  When Hank powered up the main thruster the float line demonstrated the laws of entropy.  A few minutes with Hank's onboard scissors solved the problem.  Because I was wet after the swim I worked on my tan on deck while we powered back to the launch ramp. Upon arrival I quickly put my swim shorts back on since no one wants to see a 57 year old man in a Speedo (normally I only wear it under the wet suit).

Alan,

For the video link to work you need to remove the "/," at the end

Hi all,

Shelley and I met Hank at Kootenay Lake to
photo and video his modified
Gamma
submarine.  Unfortunately, the visibility was only about
4-5 feet, 6
feet at the depth of 38 feet. 
We had great plans for recording the sub ops
and went over diver hand signals and what to
expect.  All for not and we
just did as
well as we could under the conditions available. 
Underwater
voice communications would have
been most helpful.

On the
way out we tried hanging onto the front of the submarine at
first,
but this proved too difficult for the
distance required at speed.  Shelley
was
holding one of the GoPro cameras and the lanyard slipped
from her wrist
and the camera went to the
bottom.  We spent the next 10 minutes doing a
search and recovery dive trying to find this
$600 new purchase.  As what
usually happens
when we do a search and recovery dive, Shelley found it. 
We
were back in business.  I still had the
other GoPro strapped to my head.  We
then
tied a couple of loops in the trailing dive safety float
line and this
worked out much better.  We
felt that we could almost water ski behind this
boat.  

When
we arrived over the 30 foot contour we decided to submerge
and see what
we could do.  We descended a
bit faster than Hank in the sub and lost sight
of him when more than 10 feet away.  We
settled on the bottom and then Hank
dropped
out of the sky right beside us... like inches away.  All
good.  We
carried on with the dive as best
we could.  You can see from the photos in
the Psubs.org Event photos,
http://www.psubs.org/projects/1403928245/gammakootenaylakejul15/,
that the
viz was pathetic.  We did not
go deeper due to the bottom being in the way
without being towed quite a long way off
shore.  As it was, the built-in
flash in
the camera went off due to the low light, causing too much
back
scatter.  We really wanted to stay
shallow so that we could use available
light, but such is the way of things.  

We were towed back to the
launch ramp and after changing out of our dive
gear I went out with Hank as a passenger.  We
travelled further along the
surface to the
100 foot contour where we submerged and descended to the
bottom.  I only had my point-and-shoot camera,
not a GoPro for this dive
(don't know
why), and took a few pics out the dome.  After satiating
ourselves with the awesome views of the mud
bottom we surfaced and returned
to the
launch ramp.

Hank's
submarine is a most excellent vehicle.  It has enough room
for two
occupants to comfortably enjoy the
view out of the amazing front dome.  The
LED light bar lit the scene to what seemed like
daylight.  The high level of
battery power
allows for a long transit and also powers the onboard
compressor to refill the compressed air tanks
enroute.  

Hank has
mastered the launch and recovery tasks with his purpose
built
trailer.  It is of sufficient length
to launch the sub from most launch
ramps,
but it also has a large dolly wheel so that the trailer can
be
detached from the truck and submerged on
a tow strap if necessary.  Hank
installed a
cat walk and hand rail on the forward part of the trailer
so
that he can easily detach the submarine
from the trailer while he wears
chest-waders. This allows him to tie the sub to
the dock and then park the
truck and
trailer.  He can launch or recover the submarine himself in
five
minutes with no other help or equipment
needed.

It was a good time
and the dive was good (Shelley and I do a lot of low viz
dives).  A better viz day in the spring or
fall would have made a more
interesting
photo shoot.  None the less, we had a good time.

Tim

Hi all,
I went
out to Kootenay Lake and did a dive with Tim and Shelly
Novak
yesterday.  I met an engineer from
Ontario, I showed him my killer light and
he
said "why don't you pot the whole thing instead of
oil filling"  Hmmm I
had no response,
he also said they have potted LED's for use in
chemical
environments.  I use a crystal
clear casting resin for making electrical
penetrators.  Might be worth a try.
Hank
