Hi all
The following is a report on the dive that was conducted in FL last week, 
the bases for the report is to help anyone who ever attempts this kind of 
dive, it also is for the collective minds of this list to ponder a better 
way to conduct this dive. I will not engage in debates over the way we did 
the dive or the fact we did it at all, but will pay close attention to any 
constructive comments to improve the next attempt. I am still willing to 
improve my diving. All flames will be ignored.

     Over 2 years ago I was ask just how deep could I really dive with a 
goal in mind. I never really pondered that question before, all the deep 
wrecks that I had been pursuing had already been identified and offered 
only the challenge of the depth safely along with the joy I get from wreck 
diving. After 2 plan trips to FL to dive an unknown wreck in 460fsw had 
been cancelled due to weather and current, Rick Atkins and I finely made 
the dive on March 1, 2001 with a huge amount of support, which I will detail.

The site which sits in  460-470fsw by bottom machine(the boat depth finder) 
was found by a local commercial fisherman several years ago. Capt. John a 
life long commercial fisherman and expert on the local currents had found 
this wreck. I cannot tell you his full name or boat as he does not want to 
be followed to his fishing sites. Over the years the tensions that caused 
fisherman and divers to be at odds were being put aside by some local dive 
Captains. Often telling the fisherman what they see on the dives, so the 
fisherman can earn a living a little easier. Fisherman by nature do not 
give up their sites as that is where they must go to catch the fish and do 
not want it over fished. On one fishing trip Capt. John had an object hung 
on his grapnel when he brought it up, though he does not know what it was 
because it fell off the hook at the boat and he only got a quick look at 
it, then sank back down. The object having stirred Capt. John's interest 
caused him to ask my friend Capt. Leo could divers go that deep and did he 
know anyone that would.

It is well known that Capt. Leo does not run technical diving trips, but on 
special occasions he has done it for certain divers, once to take the WKPP 
to search for the 3 missing divers in the WPB accident and all other trips 
have been for me. His willingness  to take me on these dives comes from 
several trips in which I came with other rec. divers and he never really 
knew anything about me and judged me on what he saw. Though I stayed within 
the boat rules all the time, he knew I did not like reefs. He is the most 
safety consensus Capt. I have ever seen. Over time he has come to know me 
and we trust each others judgement, which lead him to ask me that question. 
He then told me about the wreck and plans were talked over, I do not take 
these deep dives very lightly, when the slightest thing goes wrong divers 
die at this depth, that list of names is long, I don't want my name on it. 
I understand that anything can happen, I do the best I can to ensure those 
that are there do not feel that anything is their fault should anything 
happen.

Having picked the date for the dive, the plan was worked on. I asked Rick 
Atkins to dive with me, as I normally do to do the deeper depths. The 
VBtech team was told of the dive and several stepped up to help do support. 
We also planned in other dives to the Skycliff and Hydro Atlantic on March 
2, then others went to spend a week on the dive vessel "Sea Fever" and 4 of 
us stayed to dive with Capt. Leo an extra day to another unknown wreck at 
70ft and came home.

Rick Atkins and Gary Sanderson drove down a day early to prepare for the 
dive. Dave Widen, Bill Ripley (who just completed his full cave from Steve 
Berman), Ike Bullock, Nancy Hite, and myself drove all night to get to FL 
in time for the dive at noon on the 1st. Capt. Leo had arranged for Capt. 
John to hook the wreck and have a ball on the line he uses as a marker when 
he fishes it. If the current was not strong we would go down the line, if 
it was we would go up current and drop on it. Capt Leo also had Roger Harty 
a local EMT and diver on board to monitor us before,during, and after the 
dive. Roger, who also dives, did a great job as safety diver at the 20ft 
stop as he stayed very close to monitor us as we were on 02, that is where 
I believe the risk is the highest on these dives. He also made the chamber 
aware of the dive. Boyd Stewart, the DM for the boat also helped ease the 
stress with his playful humor. John Fine a diving writer was on board to 
cover the dive. A briefing was held over top "Dive Shop II", it covered all 
the possibilities and the plan. Each member of the team (both divers and 
support)  was introduced and stated what their task for the dive was. A 
complete review of the dive plan, gas mixes, deco mixes, gas management, 
safety procedures, contingencies, and time sequences were covered.


Capt. John departed to go hook the wreck, we had our gear loaded and 
departed shortly after him. Capt. John hooked the wreck just like he said 
and it was clear there was a strong current, Ike Bullock tested the current 
to see if we could go down the line, he could not do it in a single tank, 
so we could not with stages and doubles. Capt. John had told us at the 
briefing that the site sometimes has a north current on top and a south 
current on the bottom. This would be bad as we could not hit the wreck by 
dropping on it up current and would only result in a bounce dive. The 
current was plotted by GPS and sight of drop was planned for a descent time 
of 5-6 mins to the bottom, I had thought we would be there in about 4.5 
mins, but chose not to use that time so not to miss over the wreck and have 
to swim into the current to get to the wreck at that depth should it take 
longer to get there. Capt. Leo set us up for the drop, Capt. John 
maintained his boat over the wreck and with the ball just behind him gave 
us the straight line sight we needed for the drop.


DIVE! DIVE! DIVE! was the call and we hit the water, Rick lead because he 
was pushing a video camera, I kept an eye on him because that is what 
should be done when a camera is involved and Ike followed us down to 130ft. 
At 2 mins and 200ft I made my gas switch as Rick watched, I did the same 
for him at 220ft. We pushed down, the descent rate was increasing, at 300ft 
it became very dark, at 400ft it got very cold. We started to put the 
brakes on, I past my plan depth of 450ft, 460ft, 470ft, at 483ft I leveled 
off and Rick touched the bottom at 490ft, we had to go to back up tables. 
As most should know there is a 3% error in the UWATEC, Beuchat, and other 
fresh water calibrated depth gauges we use when in SW, I leave them in as a 
safety factor for these deep dives. With the depth reading of 490ft it is 
really only 475ft.  There was no current at all on the bottom, I knew we 
had landed up current of the wreck, 4 mins to the bottom, faster than I 
thought. For the next 4-5 mins Rick filmed as I looked around for the 
wreck, I came over to him and called the dive, at 7-8 mins BT we started 
our assent. At around 400ft I could see bait fish in the distance, at 270ft 
we deployed Rick's Halcyon lift bag with my reel. I was told the bag hit 
the surface and then sank, caused a bit of stress on the boat, they had no 
way of knowing we were fine. I knew the bag sank and let the line slide 
through my fingers as we continued doing our 1 min stops. Dave dropped down 
on our bubbles, with Gary just behind him, to check us out and we resent 
the bag up at 170ft and the thing sank again, the pressure relief valve 
would not reseat once the gas expanded in the bag. Dave scootered a 
permanent line over to us with a float ball on it for us to deco on, Jon 
lines were deployed to prevent us from sinking should we pass out for some 
reason. Dave and Gary had extra gas with them should we need it. We 
finished our deco with all divers taking turn to monitor us and removing 
used stages, the support team delivered our 50/50 and 02 to us, the running 
joke was that it been the most documented deco ever done, as most of time 
there were at least 4 divers in the water. We boarded the boat "Deeper" 
with Capt. Leo and headed for the dock. The dive was much to big to keep 
quiet that morning and word had spread around the dock, as the boat rounded 
"Two Georges" at the end of the marina cheers could be heard from the 
patrons for our safe return. I was unaware that no one had ever tried a 
wreck dive that deep there before, which kind of surprised me.

Back at the dock, I talked to Capt John as he was very curious to what we 
saw and bottom condition. I told him what we saw and when I mentioned the 
bait fish he said were right at the wreck, that he was marking bait fish 
just in front of the wreck, our bag had surface right over the wreck the 
first time.

We all dived the wrecks "Skycliff" 200ft and "Hydro Atlantic" 170ft the 
next day with a 3 hour SI, I found the "Hydro Atlantic" a very nice dive 
and will do that one again for sure.
