In June of 1993 the Third International Human-Powered Submarine Competition
will be held in Fort Lauderdale, Florida. The field will be composed of
over 50 entries from the United States, Canada, and Europe. Over the twelve
days of competition the subs will compete for the best speed on an one-
hundred meter straight course and head-to-head against another sub on a
course of about 800 meters. The world record for the fastest human-powered
submarine is expected to be set. Also, several awards will be given to the
submarines which excel in use of composites, cost effectiveness, and
innovation, amongst others.
 
During the second International Human-Powered Submarine Competition, held
in 1991, both printed and visual media responded. The event was covered by
CNN, ABC, National Public Radio, Monitor Radio, over twenty magazines, more
than seventy newspapers; including both The Seattle Times, and the Seattle
Post-Intelligencer; and numerous affiliate news agencies both local to the
race and at the individual submarine's home location. In addition, the
vehicles found publication in graduate theses and as the central focus of
two engineering conferences.
 
A local entry, the Triton team, is currently seeking donations. Donations
are tax deductible through an organization created to facilitate the
production of this submarine. While much of the submarine has already been
donated in the form of parts, CAD and CATIA time, machine shop time,
milling time, and life support equipment, there remains a need for funding
to cover travel, race fees, and many of the miscellaneous components, such
as hardware, paint, and contingencies. In addition to funding, persons with
an advanced SCUBA background or upper level electronic engineering
experience, that believe this project might interest them, are encouraged
to respond.
 
All primary sponsors of the Triton submarine will have their (or their
companies) name printed on the sub and team T-shirts, and have the ability
to borrow the submarine to display at their place of businesses. Further,
the sub will be seen by thousands of people at boat shows, test runs,
promotional events, and at the races in Florida. In order to keep primary
sponsors apprised of team happenings and events a bi-monthly newsletter is
being published.
 
If you have any questions or are interested in this project please contact
us though return e-mail.

Join. The accident insurance is underwritten by an independant insurance 
company. (When you get your membership and insurance cards you get a 
policy from the insurance company.) I haven't heard of any insurance companies
going belly-up during the current bush problems... err, I mean repression,
I mean recession. Sorry. ;-)

DAN has been short of funds but they continue to operate the important stuff.
I think we'll see Alert Diver not be published before they stop the phone
support. And by all means send a little extra with your membership fee. They
can use the money.

I'm like Chris, I climb in addition to diving, the idea that the helicopter
ride is free brings a lot of peace of mind.

Yes, I seem to have lucked out on the unit that I have as well. It's a
Pro, that's been on well over 150 dives at this point, many of them deep
(the deepest was to *****CENSORED*****, and believe me, having those big
digits and easy to read display makes a big difference when you're
*_HEAVILY_* narc'd).

I've run into this several times myself (always with fully redundant air
on my back, of course, but I digress). The Delphi/Phoenix uses a moving
average calculation for air consumption, that considers 500_psi as being
"0 minutes" of air time left. From what I can determine, the window of
the moving average is about 2 minutes.

Anyway, when I first bought my Delphi I considered the air computations
an annoyance, as I thought, "Damn it, I don't want to know how much
longer it'll be until I get to 500_psi, I want to know how much air I
have left in TOTAL!". I have since changed my tune on that. Even though
I am pretty dern rigorous about returning with 500_psi, I find the
Delphi's air calculations help me discipline myself, and just like Dave
D. Story (congrats Dave!), it has come in handy under less than ideal
mental conditions.

I'm headed out for a week on a live aboard on the great barrier next

one of 2 different dive computers for the trip. A "Skinny-Dipper" or a

Any recommendations?

Went diving last weekend trying to see the Leopard Sharks which I
have read some posts about on this net. Ran into a school of about 
fifty Spiny Dogfish Sharks ranging from about 2.5ft to 5ft. Spent 
about twenty minutes watching them.

There was about thirty five to forty of them in a large center area
swimming in a circle about twenty feet across. More were thinly 
spread out around the outer areas. We spent most of our time at the
edge of the dense area in the center. Every couple of minutes one 
would come right up to us and check us out. This was wild!!!

I was later told by a local that this school comes back to the kelp
beds around Copper Roof every summer. He also told me this breed of
shark is pretty long lived, up to about fifty years. I dug up a
couple of books on fish and sharks and found out that they do live 
up to fifty years in the Pacific and about forty in the Atlantic.
This type of shark is also known to hang out in schools of very 
large numbers. They also hunt and feed together in large numbers, 
which is how they got the "Dogfish" part of the name. The "Spiny"
comes from the fact they have one small spine protruding along the
forward edge of both dorsal fins. This spine is mildy venomous,
and has never been documented as fatal, only painful. 

This is my first shark sighting in my five years of diving and I
hope it won't be my last.

I consider myself a "big guy" too: 6'4" tall, 240#, 50" chest (pretty large).
I don't consider my legs to be longer than usual (32" inseam), but most of my
height is in my torso.  However, I have litte trouble fitting into my size 3
Viking Sport. Viking also makes a larger size 4, but the size 3 is almost a 
"custom" fit for me. (I am trying a over-size Nokia neck seal to accomodate my
18" neck.) The only person I know that has not been able to get a good fit in a
dry suit "off the shelf" is 6'4" and "all legs" (plus he does a lot of beach
diving which can be hard on a dry suit).

Viking offers factory customization on all of their suits, including the two
most popular models the Sport and the Pro.  Only the leg and arm length, and
the boot size can be altered on the Sport (black) and the Sport Classic (red).
Almost any alteration is available on the Viking Pro, including leg length, arm
length, boot size, leg diameter, arm diameter, torso diameter.  The most 
expensive alterations (torso) will cost about $120 each.

Viking suits may be more expensive than the White's that your're considering,
but everyone I know who owns a Viking suit praises them highly.  You can call
Viking America in Ohio if you have any trouble locating a Viking dealer, or you
just want to talk to the factory, (216) 349-1319 or (800) 344-4458.

I can also recommend the new edition of _DRY_SUIT_DIVING_ by Barsky, Long, and
Stettin (Watersport Publishing).  I gives lots of examples comparing several
different manufacturers' dry suits (Viking, DUI, Poseidon, Parkways, SAS, etc).
Steve Barsky is (or used to be) the national sales manager for Viking; Dick
Long is the president of DUI, and the designs their dry suits; Stettin also
works for DUI and designs their suits.

If this is your first dry suit, work with an instructor and get some practice
in the pool before you start diving with it.  It's a new piece of gear to which
you'll want to acclimate gradually (donning & doffing, buoyancy trim, over-
inflation procedures, self-righting, etc.)

Perhaps someone else can supply similar information on other manufacturers'
"shell"-type dry suits, DUI, Nokia, etc.

     Although r is indeed the gas constant (a bugger factor to make
all the units come out properly), n is definitely not a constant.
It's the number of moles (6.02E23 molecules) of gas in the container,
and is definitely needed for this discussion, because stuffing more
air into the tank increases n by definition.

     Note that increasing n can increase P while leaving T constant,
and this is the case after the tank has had time to cool back down
to ambient temperature.

     Having now used up everything I remember from my thermodynamics
course, I find myself back at the original question: why did the
tank heat up in the first place?  (I could probably find my old
textbook somewhere, and it probably has the answer; I wonder whether
I could understand it yet...)

With much regret, I find that I cannot go on a trip arranged
by the Northern California chapter of the Underwater Photographic
Society that I have already booked and payed a deposit on.
They have been doing similar trips once a year for some time,
and it is always rated as terrific by the participants.

So, here's your opportunity.  Take my space, please!

   DATES:  Wed Sept 23 (evening) to Sun Sept 27
   PRICE:  $480

The following is the original text of the trip announcement
from the UPS:

   "We have elected again this year to go for a four-day trip to
   the southern Channel Islands on the ENCORE out of San Pedro.
   We have also chartered a bus to haul us from the Bay Area to
   the boat and back.  We depart for San Pedro early on 
   Wednesday evening, September 23, dive Thursday through
   Sunday September 24-27, and return late Sunday night"

   "Our tentative itinerary includes, weather permitting, Santa
   Barbara Island, Catalina Island (backside), San Clemente
   Island, and Catalina Island (frontside).  (The captain has
   been instructed to have all mutineers and itinerary changers
   flogged and set adrift!)  The trip has been planned to 
   provide the best dive sites, at the best time of year, and
   with the best of company for underwater photographers and
   naturalists."

   "If there is sufficient interest, the bus can make pick-ups
   in all or some of the following locations: San Mateo, 
   Hayward, Pleasanton and Los Banos."

The price for this trip is $480 (including the bus trip from
the Bay Area to San Pedro, 4 nights on the boat, 4 days
of diving, air fills and all meals.)  You need to bring
all dive gear including tanks, weights and chemlights for
night diving.

If you are interested, reply by EMAIL, or call me at
(510) 814-8833  - leave a message if I'm not in.
