Welcome! This is a newsletter
about you- the
friends, customers and suppliers of DeepSea Power & Light.
There are terrific stories we hear from folks in the field that
we want to share. You'll see everything from manned submersibles
to private yachts, in a short and entertaining format, once every
couple of months.
We compiled the mailing list from people we've worked with, and hope
you'll enjoy seeing it. You can stop the newsletter instantly by
clicking "Unsubscribe" to the left. If you know friends
who might like to receive it, forward them a copy by clicking
"Forward to a Friend." They can click "Join our
Mailing List" and sign themselves on. Click "Send us an
Email" to do just that. Pretty easy.
Send a story: Get a T-shirt! This
newsletter is about you,
and we want your stories! We like names, faces, and a photo with
an occasional glimpse or mention of a DSPL product! Photos should
be 4x6" x 100dpi (min). Text: 50-200 words.
We'll edit if we have to. (DSPL T-shirt modeled by DSPL Receptionist,
Angie Whaley.) To see both sides and both colors of the DSPL t-shirts,

SEAmagine
SUBMARINE
|
|
 A private submersible from Will Kohnen's SEAmagine,
Inc (Claremont,
CA) is designed to operate
to 1,500-ft. The sub, christened DeepSee,
is launched from Steve Drogin's
support ship ARGO, and
its crew begins their descent into the Sea
of Cortez off Loreto, BC,
MX.
The undersea machine leaves the surface at mid-day, the
sun high in the sky over head. As the sub descends deeper, the crew
enters the "other Earth," what Jacques Cousteau once called a
"World Without Sun." It is just past noon, but night has
fallen. Beyond this point, we find the larger part of the earth's
surface that has never seen sunlight in a billion years or more.
The sub's pilot, Shmulik Blum,
switches on the DSPL 150w HID lights. Krill quickly gather in the
beam, turning the bright white light into a swirling red mass. Bait
fish appear and feast on the cloud of krill. Out of the darkness,
2m long Humboldt Squid flash into the light, grabbing the bait fish,
quickly shredding them with their sharp parrot-like beaks. The squid seem
to work in pairs, but they also demonstrate cannibalism in the feeding
frenzy. A large swiveling black eye sees the human crew. The
squid reaches with its tentacles, which are deflected by the acrylic
dome. The chromatophores in their skin flash red and they leave to
find other prey.

HROV Nereus
|
|
 Barbara Fletcher is a SPAWAR Engineering Manager working
with Woods Hole Oceanographic Institution's PI Andy Bowen on the Hybrid
Remotely Operated Vehicle (HROV), Nereus.
WHOI's Dana Yoerger
and Johns Hopkins University's
Louis Whitcomb
are co-PIs.
The HROV vehicle
has been operated during a first sea trial to 2267m,
controlled through a fiber optic tether. Designers expect to reach
the full depth of the Mariana Trench next year. The vehicle uses
DSPL's advanced single piece hollow ceramic spheres for
flotation. Each sphere is cycle tested to 30,000 psi,
more than 1.7 times the maximum pressure of the Mariana Trench.
Additional spheres were added to the HROV aft thruster section in orange
mesh bags for weight-and-balance during the initial seatrials.
These will be incorporated more permanently as the project moves
forward.
For more
information on ceramic spheres, please visit our website by clicking here. For more information on Nereus, please click here.

KOREAN TV
VISITS
|
|
 Korean Broadcast System (KBS) producer, Stella Park, and her film crew
visited San Diego
to film a segment on the future of boating. They were intrigued
with the popularity of thru-hull underwater lights. To understand the
trend, one only needs to think of a backyard pool after dark to see the
difference
an underwater light can make to the appearance and extended functionality
of the pool itself. Peter
Weber, DSPL Oceanographic Sales Manager, took the crew
for a night ride in his 20-ft Yamaha power boat outfitted with three DSPL
MiniLED Thru-Hull SeaLites. The small boat made a big hit with the
film crew, floating on a cloud of light instead of a surface of black
water. Fish were drawn to the light.
Both manufacturers and boat yards consider thru-hull lights a business
opportunity, appealing to boat owners who want to upgrade their current
boat, while manufacturers use optional lights to distinguish their
product. You can see more images by clicking here.

BAYLISS
BOATWORKS
|
|
 John Bayliss, owner of Bayliss Boatworks(Wanchese,
NC), sent photos of the
"Man-e-War," a newly constructed 64-ft sport fishing yacht,
fitted with three of DSPL's HID Thru-Hull SeaLites.
"Marlin" sportfishing magazine honors John's pursuit of
perfection by saying, "No detail, no matter how small, escapes his
attention. He tweaks all design features - structural, mechanical,
electrical and cosmetic - as close to perfection as possible."
Front end planning between John Bayliss, naval architect Robert Ullberg, and the
customer is the most important part of the building process, defining the
specific goals of the customer. Bayliss uses the finest
yacht-building materials and the best construction method for each task, according
to Nancy Brown,
Assistant to John Bayliss. Structural components such as the hull,
cabin, and bridge are CAD-designed. Computer-controlled CNC routers
cut jigs. Skilled carpenters build the interior cabinetry by
hand. Custom cockpits and bridges fit the boat to the owner,
crafted on time and within budget.
John Bayliss specifies DSPL Thru-Hull SeaLites, telling
us, "I really like your thru-hull lights."
