should be all set for the 1pm boat ride on the 22nd.
again, that's the 1pm boat.

Have confirmed with CJ, and we should be set to go.
Is Sharon going to go also?

[TommyB]

Hey Tommy, I'm good to go...Sharon won't be diving as she will be coming off a 5 day stretch. She will be bubble watching. I will have to "top" off and will do that at Fill Express. The only compressor in the area is down. (he'll do cave fills). 1p sounds good. I'll get the address off the site. Is there anything else I need to do from here??....Pay etc. let me know. Don't know what you work schedule is but if you need to talk 772-812-7070:001:

Pay the operation when we get there.
My numbers ==

407-736-1088 home
407-399-2974 cell

I run a webhosting / Game hosting business, so Pretty much come and go as I please

And I will need that address for the fills in that part of town for trimix

[doczerothree]

Hers's the address: http://www.fillexpress.com/directions.shtml The boat is aprox 5 miles for there Heading south and turning east on Atlantic.

Please note no helium, See you there

[TommyB]

Got your voice mail -- got in late.
I'll give ya a buzz 2morrow.

why no He? too hard to find fills down there, or just not worth it.

[TommyB]

I got my fills today-
21/30 so you'll want to tell the guys at fillexpress to fill your doubles with the same mix as I have so that we're on the same plan -- 21/30
So as mentioned when we spoke, just drop them off, and I'll pick them up on the way down to the boat

Plan will be 150 for 30 mins using 50% O/2 for our deco stops.

So, running the dive using vplanner we're looking at this

and ps --
I have that temp thing we spoke of on the phone--

[doczerothree]

Works for me TommyB.

17:43 Tommy I did run the numbers and they match yours.

[tj]

So how did the dive go? Any pictures?

[doczerothree]

Well... No pictures. we arrived at the dock just before 12:30 and the RAIN!! (Thunder and lightning.) I can't speak for TommyB but I was soaked before boarding the boat. The long and short of it: current and lots of it poor vis. Tommy and I took at least 5-6 minutes to pull down the line to the "Harvey" We stayed on the leeward side due to the CURRENT!! (Did I mention there was current) ripping. pulling your mask off. freeflow purging current. :) We did a limited, light sight-seeing tour of the upper deck and the fantail. My depth wasn't more than 138ft. I'll let Tommy tell you about the line "that wasn't there and the 250lb guy with the doubles that jumped in after TommyB. well not really after him...more like on top of him!!! (Not to mention the water in the boat....the water is supposed to on the OTHER side of the gunrail right!! Lots of stories from this one guys but not for the faint of heart. The best part of the trip was the meal afterward. Schedules were kept and all made it back safely. I enjoyed this dive as I personally learned just how much can go wrong and how to deal with it. Thanks for dinner Tommy!!:armata_PDT_34: Great bunch of:015: guys!!

[TommyB]

Awesome Dive!!!
Current was in the 2+ knot range.. People regs free flowing, stage bottels free flowing (I have to find out why some of these guys don't charge the stage, then shut it off) Must just be a cave diver thing??

Rain, Rain, and Rain. Thunder, Lightning stikes everywhere (did Doc mention the captain of the boat told us to not hold onto anything that was metal) WHAT !!
At least the seas were 2ft or less.

Adam In the water - I wait a few until he disappears
Off the back I go ---
I've never had 250lbs dropped on my head before, I thought I took a tox hit at 3fsw at 1 min into the dive. I see stars after hearing this very familar sound -- you know the one -- where ya drop a tank on concrete and it make that pretty DINGGGG --
And then to top it off, this bozo now begins clawing at me, pulling on all my gear (some time during this episode he even manages to do a full sumersault in front of me) -- now back to the clawing / pulling on my gear etc... So after I pushed him off me for like the 3rd time he now thinks it's ok to grab my 7ft hose -- hmmm which I am breathing on) -- so we tell self " Hey self let's go into self rescue mode and punch bozo in the solarplex, maybe he'll get the hell off of me) Funny how that got his attention and he manages to get his ducks back in a row and we continue on down the line)

You have to picture this ----
30 mins bottom time at 150 gives us about 30+ mins of deco
-- kick-butt current --
Did I mention the Current ?? 2 + knots easy --
great wreck, lots of nice critters, pretty colors, etc etc etc
Couple good swim throughs too poke around in, without doing any real penatration ---
time to leave to hit our deco stop schedules we leave a little early due to current, gas management , etc...
Up the line we go, we're the last team off the wreck (we're supposed to remove the float ball line) Not my job, no freaking way in that current :) (That's what I pay those other people for hahahaah)

So up we go, 2 teams in front us already a team of 4 and a team of 3..
Did we mention that their float ball was about 100 years old and damn near deflated?? Never knew you could actually see through a float ball :)

So here we are, hanging on to this ascent line making our way slowly to the first deco stop at 70fsw. 1 min stop here, and gas switch ---- but there are 7 people still here at 70fsw holding up the ascent -- we had to be at least 2 mins behind them, so I'm thinking WTF are they still doing here.. (Adam and I are still at about 80 ft, so a little to early to go to our gas switch mode)
Me and Adam wait a moment or two.. I'm now watching a guy doing his gas switch to 50% 0/2. He's having an issue or 2 or 3 or 4 ---- as in the current is kicking his ass :) Free Flow Reg, Stage is in Free Flow also
So he finally gets switched to his 50%, and for some reason I still have not figured out, he begins to dump his air in the BC ---
Next thing I know, were at 110fsw and still going down -- and this bozo is still on 0/2 and dumping his BC:icon_super: --- 50% 0/2 at 110fsw hmmmm
(Guessing that 100 year old 1/2 deflated see through float ball has seen better days)

I motion to Adam to had back down to the junction of the what appeared to be another 1/2 inflated float ball :eusa_naughty:
Which was in fact the float ball that was supposed to be on the surface --!!!
Team one and Team two had managed to drag the float ball down to 70fsw and they were out there hanging on the (what was supposed to be the tag line that floats on the water behind the boat))....

I look at Adam, I think he figures out by looking at my face I'm seeing this as a major cluster. I give the signal to shoot our lift bags and get the heck out of dodge before that line makes a rapid ascent to the surface. I can just see us blowing the surface like a missile when the yahoos on the other end finally get their sh%t together and deploy their lift bags. Not good when your on a 21/30 O/2 He mix... The whole "you must ascend slower when using helium comes to mind -- can you say BENT"" ---

Ohh did I mention that one of the members of team one, hooked his Jon line onto the sinking tag line, and those 3 members of team two for some reason decided to hang on his Jon line!! (You really have to hear his WTF story on this one) hahahhah I still bust a gut just thinking about it --- So you have 4 people hanging on some Jon line --

So here we are at the surface buoy which is now at about 100/110 ft (the bouy is a surface marker right??:102: Getting ready to blow bags...
Opps did I mention that the current sucked Adams lift bag right out of his hands! ?? Not a problem, I have two bags -- for situations just like this -- yea right... (one lift bag / one SMB)
I go to deploy my lifting device, I'm so proud of myself for getting it out, hooked up to the spool, changing from primary to octo -- opps, I let go of that damn line and now I'm being swept away from Adam at a high rate of speed...
So I tell self "Self no biggie, he'll catch me while I am doing the bag deploy"...
Never saw him again until we hit the surface :)
Read somewhere "Same Ocean, Same Buddy" something like that:sport24_diver:

Great dive though!!
Perfect dive on our stops.. Adam surfaced about 20 or so yards away.
Seems he found a line that was magically hanging in the ocean that was attached to someones reel -- (some one from team one had dropped their reel and it was attached to a lift bag ) go figure --
Our Run times were right on the money // within 1 min of each other..

Ohhh --
Did we mention the part where the Captain yells at us "" Hey stop hanging onto the metal on the boat, you want to get electicuted""....

[doczerothree]

Hey TommyB!!! You are toooooo funny!! Sharon had to pick up off the floor... She thought I was having a seizure:460_sim: Good dive Bro'. Looking forward to the next. And thank you!!:armata_PDT_34:

[Techdiver]

It sounds like that was an accident waiting to happen, it’s nice to laugh and have fun, but our sport can be deadly.

Let’s look at the serious side for a minute. Hope I'm not out of (line) here? But was safety ever a concern. Only last year a diver was struck by lightening and killed while in the water. Maybe this was a bad time to dive, sounds like the equipment on the boat wasn't up to snuff either.

We all have to remember that we have to look out for our own safety and some times step up and tell the Captain when it not safe to go out and dive. I understand that they want to make money and you want to dive, but that's not worth a life. Just because a Captain wants to go doesn’t always make it safe.

We should all look at the equipment on the boat and decide if it is safe along with the weather and the condition of the water.

1st Lightening not a good time to be in the water. :102:

2nd Current really strong safe or not you decide? :102:

3rd Conditions of the Bouy, unable to float? :eusa_naughty:

4th Was the crew capable of performing a rescue if needed both on the surface and below the surface? :102: (Not of the bailing the boat out)

5. Are the other diver capable? Do you know? :102:

6. Was the Captain right in going out in the weather? :eusa_naughty:

7. Was tying off to the buoy wise? :eusa_naughty:

8. Should you Consider the gas you diving and the conditoins both. :icon_neutral:

9. Can you deploy you safety equipment in thease conditions?

I'm not picking on anyone, but sounds like some poor decision making on this dive. I've been there done that, I'm guilty of the for mentioned. Just food for thought. Glad your all safe. :armata_PDT_34:

I have some good friends out there and don't want to loose them. Please be smart and safe. :armata_PDT_34:


Thoughts anyone? :icon_idea:

[doczerothree]

TommyB and I discussed some of those issues prior to getting into the water. Some of the issues came up once in the water. No, you are not out of line.:icon_exclaim: Thank you:001:
