Photos and Story by Robin Jacoway

As I waited for my luggage I began to realize that all around me were people from the military. I came from a navy town in San Diego, but this was different. As I glanced around at the other passengers arriving and began noticing their local counter-parts it soon became apparent that this is a real military town. Then it dawned on me, not only was Norfolk an important base of operations for our country?s service men and women, but this was also the birthplace and backbone of our nation?s naval defense.

I arrived in Norfolk, VA at 11:00 pm, the first portion of my journey to join a team of divers whose destination was the USS Monitor. I was meeting Mel Clark, Curt McNamee and Judd Dunlap at the hotel. The plan was to get a good night?s sleep and drive to Hatteras, NC the next morning. We rented an F-150 crew cab truck, loaded it with all our gear and barely had a place to sit. If this truck veered off the road, it would cost more to replace the gear than the house it crashed into! We had three Digital SLR?s with UW housings, dual strobes, one HD video camera with UW lights, four closed-circuit rebreathers, four laptops; oh yea, lots and lots of other dive gear.

Looking at the map, Hatteras did not seem far away by car. As a matter of fact, many of the locals told us it only takes an hour and a half to two hours to get there. Four hours later we arrived and were greeted by Rick Marshall, diving legend Mike deCamp and his lovely wife Wesley. Rick informed us that there was a group out diving that had been there the prior week and needed time to shower and get their things together before we moved into the house. So, what do divers do when not diving? We talked about diving, then started to put our gear together and formulate plans for the week.

A few hours later we joined the rest of the team for dinner at our second rented house. As we arrived Joe Dobarro and Tom ?Motz? Grothues, both from Rutgers University, were preparing the REMUS 100, an autonomous underwater vehicle (AUV). The REMUS 100 is very impressive torpedo shaped AUV, slightly less than two meters long, nineteen centimeters in diameter, and can dive to one hundred meters. We were excited to hear Joe and Tom explain its new mission to map the Monitor in 3D, as well as collect other scientific data from the wreck site.

As we gathered for dinner I realized we really had a great team of people, each offering their own unique skills to help us achieve our goals. Our first objective was to secure a mooring to the wreck, then assist REMUS in its mission, and finally take as many useful videos and still images as possible showing the current state of the wreck during our dives. If that was accomplished then we were to see if any voracious lionfish had made their way up the Gulf Stream to the Monitor, and document the quantity and location on the wreck site.

After dinner that first night we were advised of the following days plan. Dan Crowell and Bob Ryan were tie-in team one. Their job was to find the existing mooring line and shoot the end of the line to the surface with a 250lb lift bag. Rick and I were on tie-in team two. We would either be finishing the job, or inspecting the tie-in points to make sure they were strong enough to handle the weight of our charter boat and the divers. The remaining divers would go to a local wreck to do a warm-up dive to make sure that their gear was ready to go for a deep dive to 240 fsw, with strong current likely.

Dan would also lead a production team in generating daily ?inews reports? that would be posted on the Monitor National Marine Sanctuaries web site titled ?Graveyard of the Atlantic Expedition 2009.?

Every dive trip has some type of drama, this one was no exception. Right after our first team meeting, Rick received a phone call from his wife, Romi. The adoption that he and Romi have been working towards for the past ten months was happening immediately and had to be on a plane headed to Alabama the next morning. The timing of this was unbelievable and bittersweet! Rick began to pack his dive and video gear, make travel plans and delegate duties in order for the expedition to move forward in his absence.

Sunday at 6 am, Day One: Everyone was awake anxiously anticipating that first dive and what the Atlantic had in store for us. As I went upstairs to get my morning caffeine (ice cold diet coke) and breakfast bars, a few grumblings were heard about not everyone getting to dive the Monitor today. This passed as we realized one anonymous diver left several diet cokes in the freezer from the previous day. Frozen cans of soda eventually explode, an unexpected mess for our perpetrator to clean up. Needless to say, he took some kind ribbing from his peers that morning.

As I arrived at the ?OC Diver,? Captain Ted Green was assisting the REMUS crew to load the AUV and secure it to the boat for a rough-water journey. The rest of us loaded all of our gear on-board, including two large production quality SONY XD Cam cameras, two Amphibico Z7 underwater video systems, still cameras and lots of tackle to bring the REMUS back onto the boat.

The clear blue sky was misleading; as we pushed through the channel we could see the force of the colliding currents and why this area is known as the ?Graveyard of the Atlantic.?

It was a two-hour boat ride out to the wreck site of the USS Monitor. Or at least to what we thought was the wreck site. We used the GPS coordinates given to us, only to find nothing but fish and sand, not even a bump on the depth finder! After ?mowing the lawn? for another hour, Ted and Dan?s Atlantic wreck diving experience paid off and we found the wreck.

The weather still looked good but the current was cooking. After Ted was assured he had the right hit for the wreck we went up current and drifted back in order to measure the speed of the current and to time how quickly we would be over the wreck.

Captain Ted made the decision that if we were to dive that day, it would have to be immediately and we would have to be sand darts in order to hit the wreck. We donned our gear; pre-breathed our rebreathers and got ready to dive. Ted put the boat into position and we stood on the stern, waiting for the command to go. As the boat got near the target Ted yelled ?dive, dive, dive!?

The three of us jumped in perfect syncopation and began our decent as quickly as possible. I descended with my hand on my diluent add button kicking down as fast as I could. When we finally reached the bottom we could see the starboard side of the wreck faintly in the distance. As we swam closer we realized that we were very close to the armor-belt that the Navy divers had previously cut off in order to remove the turret during a prior Navy mission. The armor-belt was much larger than I imagined, coming several feet off the sand and fifty feet in length. We then swam against the current to the bow of the Monitor to look for the mooring line from the previous year?s expedition. We finally found it with some milk crates attached to a big tractor tire about fifteen feet off the port bow.

Our plan was a twenty-five minute bottom time with a ninety minute run time. Unfortunately, the mooring line was tangled throughout the wreck, and snarled into a large mass back to the armor-belt where we had first been. After twenty long minutes of untangling and freeing the line, Bob tied on the lift-bag and shot it to the surface. We had now been on the bottom for thirty minutes and were forced to use our longer contingency table.

This meant we needed to do almost ninety minutes of decompression with almost a two-hour run time. The current was quite strong on the bottom, which meant it was going to be stronger as we got closer to the surface. By the time I ascended to my forty-foot stop, I deployed my jon-line and clipped off. The water was stunningly beautiful, but it was much darker than when we started the dive. As I looked up I noticed the wave action; I could tell our surface support was not having a very good day above us due to the increased wave height and strong wind.

I had only completed half of my decompression when I looked up and saw rain pouring down onto the surface. By the time I arrived to the twenty-foot stop I could see the OC Diver clearly doing thirty degree rolls inside the troughs of the waves. You could almost see the crew looking over the side down on us. I felt very fortunate that I was down here instead of on the boat. As we climbed back aboard, the wind picked up to gale force strength and the rain pelted us from all sides. We tied two large mooring balls to the line and decided to just leave the lift bag there for the time being.

Our mission complete, the OC Diver finally headed back home with the storm at her back. When we returned to the marina, the rain had stopped, the wind had died down and the skies almost looked blue, but looks can be deceiving. After dinner we went online to investigate NOAA?s weather buoy located near the Monitor site. The storm front was going to build over a three-day period. With a poor weather forecast we decided we would cancel diving operations for Monday.

Tuesday appeared to be another nice day, the storm front had subsided and we were going to make another attempt. Our team?s first priority was to get the REMUS into the water; if we could just get it to fly its mission we felt like we would have time to do more first-hand investigating on the Monitor as divers.

We deployed the AUV transponders; and quickly saw that the current was just too strong. These transponders are how REMUS understands where it is in relation to the target so it can complete its 3D mapping mission. The combined weight of the mushroom anchors and extra lead were not enough to keep the transponders in a fixed position, a requirement for accurate mapping.

With the transponders dragging across the ocean floor, the REMUS mission was scrubbed. Between the current and the weather taking another turn for the worse, we reluctantly decided to cancel diving operations for the day. Though we were all disappointed, we knew it was the right decision to keep the team safe.

Wednesday, Day 4: Once again we loaded REMUS and our dive gear, and then headed out. The sun was blasting down on us and there was just a light breeze. As we motored out, all of us had high anticipation and wondered if today was going to be the day we got to dive the Monitor. Shortly after getting out of the channel and into the open ocean we decided to do a test run with the REMUS. The transponders were deployed and once again we could see that they were going to bounce across the bottom with the strong current of the Gulf Stream. After recovering the transponders, we decide to go on to the site and just see what the weather might be like.

We radioed Captain Art Kirchner of the Margie II to advise the other dive team of our plans. Though all of us were afraid to get our hopes up too high, we were at least encouraged about the thought of going back to the wreck.

When we arrived it seemed relatively calm, only a slight breeze and very small waves. Ted motored up current from the target to check the speed of the current; it was 1.45 knots. It took about an hour for us to get the boat ready and the deco stations set up.

The plan was for Dan, Bob and me to do our dive, check the integrity of where the mooring line was chained to the tire, take video and stills, then shoot a bag; the signal that it was okay for the Margie II to send divers down.

Descending to the wreck I had made the mistake of not attaching my underwater camera to a leash. I chose not to do this in order to protect the large dome port of the wide angle lens. As I inched hand-over-hand down the traverse line going against the current it became increasingly difficult to both pull myself forward and hang onto my camera. Ten minutes later I finally reached the down line at 100 fsw and began to relax again, and catch my breath. Fifteen minutes going into the dive we finally had reached the bottom. The dive seemed somewhat surreal, marine life passing by me in slow motion, the wreck a peaceful and quite setting, jacks darting about and sand tiger sharks wondering why we were there. The water was a beautiful blue, visibility was awesome, over 100 feet, and the water temperature a very comfortable 70 degrees.

I began moving from the bow to the captain?s quarters. Jeff Johnston of NOAA advised us to look for a PVC pipe that had sampling equipment in it. I really wanted to find this and take a picture of it. I knew the clock was ticking and couldn?t find it so I decided to move further aft clicking as many pictures of the bottom of the wreck as I could.

As I worked with the current amidships and then over the boilers and the engine frames I realized that my dive time was now twenty one minutes so I decided to start my slow swim against the current on the bottom on top of the port armor belt. As I swam forward I noticed Bob heading back to the mooring line. Dan had been shooting the port hull structure where the cement bags had been placed to support the hull structure from collapsing. As I returned to the bow Dan swam up over the armor belt and then over the anchor compartment videoing everything for later analysis. As I swam to the ascent line Dan swam past me and went off to the other tractor tire lying in the sand.

There was another tractor tire used as an old mooring an additional 30 feet from the port bow. He turned, and then it was apparent to me what he was doing. He was trying to get the whole wreck into the frame. He glided quickly back to the mooring line and we both began our long ascent back to the surface.

Arriving at the first traverse-line at one hundred feet, I noticed Mel and Judd climbing down the mooring line. As I made my way towards the rear of the traverse line I realized my camera was going to be a liability as the current had picked up considerably since the start of the dive. With one hand on my camera, and the other on the deco line, I had to figure out how I could free up my hands to relax. I could not release my grasp of the deco line for fear of winding up in the shipping lanes. Finally, I decided to use the double-ender on my primary reel to attach a length of rope I had in my leg-pocket. Then I could attach my camera housing to the jon-line I was previously using. It worked, though my big YS-350 strobes blew-over to one side of the system, knocking against my body. The camera was protected and the strobes trailed behind it, enabling me to free my hands and relax during my remaining hour of decompression.

As I ascended to my twenty-foot stop, I noticed more divers beginning their descent. One of them was having trouble going down and decided to take the traverse line to go back up the deco line, aborting their dive. The current made this a very challenging dive, but at the same time, very gratifying.

Thursday, Day 5: We make another attempt only to find the current was now 2 to 2.5 knots. The two mooring balls were completely submerged below the surface, with no hope of popping to the surface. We radioed the other boat and advised them to change direction to an alternative wreck site. Since we were already there, we decided to jump in to cool off and maybe get some video footage while free diving near the NOAA weather buoy.

Friday, Day 6: This was our last day of diving operations. Reluctantly, we decided the weather is just too rough for the Monitor and make plans to go to another site, giving REMUS a chance to strut its stuff. When we arrive at the wreck we find a local charter boat, which we had radioed with our intentions as he passed us on our way out, tied into the wreck. We cannot safely conduct a REMUS mission with divers in the water, so we disclosed to him that we are going to a new secret NOAA target instead.

The explorer Bradford Washburn once told me that to go to the top of Mt. McKinley, or even Mt. Everest is a picnic, even a walk in the park, as long as the weather cooperates. It is the judgment of the explorer and his experience that keeps him alive. The lack of experience combined with the lack of good judgment is what gets people into trouble and ultimately a situation that they can?t overcome. I feel very fortunate to be associated with such an experienced team of people that showed good judgment and put the safety of the divers as its top priority. Dan, Rick, captains Ted and Art, safety divers John Billings and Karle Smith, and the rest of the team made this trip successful and fun.

As a team, we only did one dive on the Monitor, but it was a great dive. No one got hurt and we produced a lot of video and stills for NOAA to utilize in their assessments and for future site management. As for Rick, a new dad to a baby boy named Jack, he?ll be back next year. After all, the wreck won?t be going anywhere, and NOAA assured us access to the site would continue for divers.

A bit of background for those who don’t know much about the Island: Corsica is the largest french owned island (3,351 sq mi, roughly the size of Porto Rico), south of the mainland (110 miles), just north of Sardaigna and west of Italy (56 miles). As such, it is in the Mediteranean sea and enjoys temperatures in the high 60s at depth in the summer (and mid 90s on land). Corsica is very mountainous above the water and many of the large boulders found on land can be seen underwater. It has a lot of costline (620miles). One can fly to Corsica through Paris (Orly) and Marseille (MRS) as well as take an overnight ferry (with a car, which is what I did). Those are very large ferries capable of transporting 2000+ people and 700 cars.

Raised in the south of France, I had never been to Corsica and didn’t quite know what to expect (you don’t usually vacation in the Dominican Republic when you live in P.R.). I chose Corsica for this dive vacation because it was a good place to take my parents (for my dad’s 90th birthday), an easy place to get to, far away from where I now live (Boston) and a beautiful island to boot. Furthermore, the presence of a rEvo instructor implied a rebreather friendly structure in Porticcio/Agosta on the west coast where we stayed (we rented a 4 bedroom villa for $2000 a week or so).

I dove with Corse Plongée, owned by Nicolas Caprili (FFSSM, PADI & IANTD instructor). Nicolas has put together a great team with Laurent, Tristan, Thomas & Guillaume. I emailed him in advance so as to make sure he had sorb, helium and O2 for me. Air France was kind enough to misplace my rEvo III for 5 days so he even rented me a rebreather until I finally got mine back.

I did four dives with Guillaume, a new instructor in the club who arrived the same day I did. Diving in a mixed team (OC, CCR) was a first for me and Guillaume was a very good buddy. We discovered a plethora of sites together. France and Corsica are on a more mellow diving schedule that I am used to and people generally only make 2 dives a day (one in the AM, one in the afternoon). I made four dives in 25-30m (80-100ft) with Guillaume, most of them with no deco (Guillaume did have some deco, diving on Air). The night before the last day, Nicolas and I prepared for a Normoxic Trimix dive, filling dil, O2 and bailouts (21/35 and EAN 40). The next day we made a really nice dive to 55m.

Some more details:

• I dove with my new Pinnacle 5mm Merino. It was ok for 60mn dives in 65F water (at 25-55m) but not warm. The suit seemed a bit stiff and maybe a tad small when I first got it but it fit perfectly and felt great.
• Corse Plongée lent me a few bailout bottles. They are steel 65 & 72 I think and as such very negatively buoyant. So buoyant in fact that with a pair, at 55m my rEvo wing couldn’t lift me off at all. I had to cut off Nicolas’ trim weight and he mine. They work well though
• I brought my own Travel Stage Bottle Rigging (one from DR and one from Deep Sea Supply which I really dislike – Tobin and I got into it once and he really doesn’t stand behind his products). It made it easy to grab any tank and rig it quickly to be a bailout bottle. They take little space and are good to have.
• While Corsica has a few wrecks around its coastline, the gulf around Ajaccio where I have is mostly tempered water reefs. They are beautiful, very tall boulders populated with much sealife. We’re talking 60m+ tall moutains of boulders, on top of each others in what sometimes seems to be precarious balance. We saw large fish (Dentie/Dentex/Brem – Merou/Grouper), lots of Chromis Chromis, lots of Scorpion Fish (ate one at dinner), tons of wrasses, nudibranch, quite a few spiny lobsters (juvenile and large specimen), octopus. Often, looking up from 20m, the water would be filled with hundreds of fish all the way to the surface. At 55m, I was delighted to see a lot of Anthias, one of my favorite specie. I even caught a glimpse of a Mola Mola/Sunfish/Mole/Poisson Lune) in the water and at the surface (√-check, it was on my list of things to see). In any case, lots of fish but I want to make sure I put an emphasis on the underwater scenery, those large boulders are fantastic, beautiful underwater structures.
• Corse Plongée has two ‘semi-rigide’ – zodiac like boats with a solid bottom. They’re easy to get into (christmas tree ladder) and out of (roll over). As a rebreather diver, they always let me splash first and come back on the boat last, very nice. Before diving you load up all the gear in a truck, walk 100 yards to the beach, bring the gear in the boat and go dive. Most dive sites are 10 minutes from the beach.
• The rEvo III mini hybrid worked really well. Doing 1-2 dives a day I flew it manually at 1.3 using the Shearwater as a parachute at 1.1. I mostly dove Air. I used stubby 3L tanks that Paul sells in Europe (3L at 200bars, I don’t know what the US equivalent is). I used a 4lbs weight for trim but 8lbs might have been better (5mm wet suit, Steel 72 bailout, steel mini rEvo III)
• I didn’t take any photos. Taking a rebreather overseas for the first time (with all technical equipment) was stressful enough, combined that those were my first relaxed dive on the rEvo that I didn’t want to bring my camera housing (though I did bring my 5D MkII and my LX3 I didn’t dive with them).

I want to thank Nicolas, Guillaume and the rest of the team for being so accommodating, helpful and making my dives great. I recommend Corsica & his organization for diving. You might not find great wrecks there but the dives are wonderful, the club is well organized and Corsica is beautiful.

Feel free to ask any questions

The default set up for my Dive Rite O2ptima rebreather is two Hammerhead handsets. The primary is used to drive the Solenoid (which injects oxygen into the loop) and provides decompression information (Buhlman GF) as well as a read on the O2 Cells 1,2 and 3. The secondary is used to drive the Diva HUD (Head Up display with vibrating capabilities) displaying information from the same cells there as well as on its display. A lot of O2ptima divers dive their rebreather this way with one handset on each arm and the HUD.

Some choose to get the optional deco capability on the secondary handset, a $500 pin code from Hammerhead and a reasonably good choice which gets you a backup decompression computer should the primary fail (and you find yourself manually running your rebreather, using SCR mode or bailing out on Open Circuit).

The O2ptima has a neat feature which allows you to install a fourth sensor that can be read from a third party computer connected via a fisher cable. That’s what I was doing with some degree of success and failure with my VR3. This gives you a second deco computer, possibly a different deco algorithm and a fourth cell to get O2 readings from. Unfortunately a fourth cell can fail or behave erratically and as such I didn’t trust the VR3 as much as I would have wanted to. It also always seemed to be reading .10 higher than cell 1,2,3 which bothered me. One could also use a Liquivision X1, Shearwater Pursuit or Delta-P VRX with this scheme, reading from one sensor.

Having switched to the Liquivision X1 from the VR3 and following closely the announcements for the PPO2 interface, the X-Link, I have been working on a solution to connect three cells to a Fisher cable. Kevin from HammerHead set my head up with a split harness and 5 wires Fisher cable so I could continue monitoring Sensors 1,2,3 with the HammerHead handsets in addition to Sensors 1,2,4 with my Liquivision X1/X-link. Of course the same could be done with a Shearwater Pursuit or Delta-p VRX.

So what do I like about this setup ?

• O2 readings from 4 cells instead of 3 with voting logic on cells 1,2 and 4 for the external PPO2 reading
• Different software and hardware. If the HH primary handset was to freeze up due to an odd software issue (as opposed to electrical) it’s entirely possible the same thing could happen on my secondary. With the Liquivision X1, I am on a different hardware and software platform, one altogether different bugs maybe but _different_ is the key. Redundancy through additional and different hardware/software.
• VPM algorithm vs Bulhman GF. Always good to have two different profiles from two different algorithm
• Different voting algorithm on a different group of cells
• Possibility to fall back to 2 cell, one or constant PPO2 if I need to
• Very easy to configure the bailout gases (not that the HH or VR3 were that hard just not very quick to configure)
• Same deco computer, parameters, profile and as such deco plan as my usual dive buddy
• the X1 is very bright which is great for dark water diving (hello Boston). Also, I can see my buddy’s PPO2 from 10 feet away
• Same software for planning dives (V-planner) and diving those plans. Plan your dive, dive your plan

And while Fisher cables can be problematic, when well maintained they are reliable. Now, I still have and use my two HammerHead handsets. With the secondary tucked away in a belt pocket, the HUD and primary remain my main dive instruments.

The Liquivision is a very good backup and could be the primary if I had a different setup (MCCR or OC, for example) and could be substituted by a Shearwater Pursuit or a Delta-p VRX. In addition to tables, of course and a deco plan written on white electrical tape.

• A decompression computer is not a substitute for planning your dive and carrying decompression tables. Plan your dive, dive your plan and carry backups tables.
• I paid full price for my Liquivision X1 (bought it used off a bloke in Canada) but I will be getting a Liquivision X-link for 50% of the list price because I am working on a 2 pager about using the X-link with a Dive Rite O2ptima for Liquivision.
• My experience is with the X1 is only with the V-Planner Live software installed. This post relates to this particular configuration unless otherwise noted.

Experience

When I bought my rebreather, I already had a Delta-P VR3. In addition to that deco computer (which I bought the Trimix and Rebreather/PPO2 software pins for) my O2ptima comes with a Hammerhead primary handset that’s deco-enabled (Buhlman GF). Having just spent so much money on diving equipment I wasn’t looking to buy a new deco computer.

Six months later, my dive buddy Sam bought a Megalodon Copis rebreather. Since the basic Copis doesn’t come with a deco capable computer (really just a PPO2 display) he chose to buy the new Liquivision X1. At the time, not much was known about the X1 but he had seen me struggle with the VR3 and thought the user interface was awful. The idea of being able to chose which software to put on the X1 was attractive as was its user interface both in terms of tapping and screen display.

I actually didn’t think the X1 was a great choice for him at the time as the X-link wasn’t available (it still isn’t at the time of this writing but should ship mid-december 2008) so the X1 could only give him deco information based on a pre-set PPO2 as opposed to reading it real time the way my connected VR3 did. I thought this was especially true of a manual CCR like the Copis he bought. In any case, he loved his X1 and after diving a few times with him as my VR3 failed again and again I went ahead and bought a used (but never wet) X1.

There is something to be said about wreck diving in the north east, about diving in a dry suit, in green and cold water. Something to be said about diving wrecks that sank in a storm, a collision or wartime. There is something to be said about the Chester Poling, cut in half in a storm, years after it had sunk.

And there is something to be said about great visibility, warm water, wrecks that you can see from the boat, after a 20 minutes trip from the intercoastal.

So four of us set off for Florida last week for our own wreck extravaganza.
We had booked two days on Captain Oliver’s Avid Diver Charter aiming to hit wreck after wreck around Pompano Beach on our rebreathers (two Dive Rite O2ptimas, one ISC Copis Megalodon and one Ambient Diving Evolution). After that we were going to drive to Key Largo to dive the Spiegel Grove and the Bibb/Duanne.

The trip was originally scheduled a month earlier, but bad weather, or a chance at bad weather, at least forced us to cancel. Last week though, we we’re on and the weather looked good, at least a few days before.

By the time Tom and his dive buddy came back up to the top of the wreck, the hook was gone and each had to pop a bag and do their deco while drifting in the warm Florida waters. While hanging at 20 feet, Tom’s line snapped and he had to pull out his trusty finger spool and pop another bag for the last 15-20 minutes of deco, while we had to figure out why a bag was floating away on its own. Lucky for him, Captain Oliver retrieved his bag, saving him $50 or so.

Day 2

The next day, the plan was to hit the Hydro Atlantic, a ship of huge proportions which sank in a storm in 1987 in 172ft (54m) of water. This was a deeper dive than I ever did, by nearly 30ft (10m). Diving with 21/35 as my diluent, an Aluminum 80 of 21/35 and an Aluminum 40 of EAN50% as bailouts, we had planned the dive carefully and executed our plan.
I couldn’t resist bouncing to the sand to look at the bow of the ship towering above me but we spent much of our dive swimming around the perimeter of the wreck then on the deck. A few minutes before it was time to go up (20 minutes into the dive) we checked out the stern and saw a huge Goliath Grouper on the way back, the size of a small Volkswagen, I am not even exaggerating. Sam said of this 53 minutes dive that it would have been his best ever had we not spent so much time on the hull of the wreck instead of on the deck. But that’s what happens when you see a wreck for the first time, you’re not really sure which way to go and what to see.

Later that afternoon we hit the RSB1 a decent wreck by all counts but lackluster compared to the Hydro Atlantic still so fresh in our minds. After that we did a quick reef dive where I shot the new Dive Rite bag (more on that later) using my new reel.

Day 3

That wrapped two great days of diving in the Pompano Beach region. The next day, we all woke up at 5AM to make our way to SilentWorld Dive Center in Key Largo. Chris has a really good store there, carrying a lot of Halcyon gear as well as some more recreational stuff. He was able to fill our rebreather tanks with O2 and partial-pressure 21/35 which was a god send since I was running low. Despite assurance the previous day that we’d be able to go out, I was nervous that we’d be driving all those miles to get blown out. Once we got to Key Largo things were not looking so good but we were told they’d tried to get us out. Tom and Eric had anti-sea-sickness patches but Sam and I had to run and buy some Bonine (Meclizine) at the local store. Surprisingly the ride to the wreck was quite uneventful and the seas were reasonably calm once we got there. The Silent World IV tied off to the buoy on the bow and we made our descent with almost no current and good visibility.

The Spiegel Grove(LSD-32) is an awesome wreck, a former navy ship designed to transport and launch amphibious craft and vehicles with their crews and embarked personnel. Sure it’s been intentionally sunk and could be seen as an amusement park for divers but it’s a gigantic wreck with many items left intact such as lunch tables, ovens, electrical closets; a wreck you can get lost in, a wreck people have died on. The Spiegel Grove is an immense boat loaded with memories for the thousands of navy men and marines who served on it (including one John Mccain). On the first dive Sam and I were able to explore a lot of rooms in the superstructure across four levels, going up, down and sideways but always with some natural light coming in telling us of a nearby exit point.

I could do ten dives on the Spiegel Grove and still feel like I’d need to come back. Even though thousands of divers have explored it before me, it felt like I was the first one here as we were penetrating room after room, their floor thickly layered with silt. After over an hour around 95ft (29m), we began our ascent, regretfully, and our decompression. As soon as we were back on the surface, Sam called this dive the best he ever had. Again.

We had planned to dive the Duanne and the Bibb in the afternoon but those wrecks being farther out, possibly in the gulf stream which was close to shore that day, we had to ‘resolve’ ourselves to dive the LSD-32 again. This time, Sam and I explored the lower parts of the ship including one of the propellers and the hangar deck. I didn’t feel right during the dive, working a bit more than I should have. Whether I was fatigued, cold or something was really wrong, it doesn’t matter, I quickly called the dive after 30 minutes or so, spent around 125ft (40m). But I had no regrets, I had had the best diving vacation ever.

Three days of balls out diving !

That dive concluded our underwater time for that 3 days wreck-athon. While the interpersonal interactions were not at their best during that trip, the diving was stellar. Diving in Florida for our small group of north-eastern divers is becoming a tradition, an escape from our tough conditions between Cape Ann and Cape Cod, an easy way to dive our rebreathers in great conditions, a few hours away from Boston. One thing that makes it very easy for us is the support we get from our local network of rebreather divers. Whether they’re diving with us or not, Adrian, Tim, James and Howard are always here to help, lend us rebreather tanks and bailout cylinders, receive our packages and send us back our gear. We can safely say we wouldn’t be diving that often and that cheaply if it weren’t for them.

During this trip, we dove on Captain Oliver’s Avid Diver in Pompano Beach and Chris’ Silent World fleet in Key Largo. Avid Diver is a great boat for technical diving; with 4-6 rebreather divers, we had plenty of room to get ready and Oliver dropped us right on top of each wreck without any issues. The French-born captain has a lot of technical diving experience and is a great source for advice and local knowledge. Chris’ venture is a little larger with a newfound focus towards technical diving. It’s great to be able to rely on a one stop shop there in Key Largo. He and his team were very helpful and his captains very knowledgeable about the Spiegel Grove. The boats are great, even in rough seas. Local support in Pompano Beach was provided by Ricky, Charles and Tony from Fill Express, simply one of the best shops that I know of.

So here you have it, my dive report on our most recent trip. I hope Sam, Tom, Eric, Howard and Mike have the opportunity to chime in. If you want to join us next time, let us know, we’ll be back soon !
