Malta Day 1 – Accidents and Emergencies, Part the Third

Spot the octopus!

We pored over the excellent dive book, planning our dive on the Tugboat Rozi, just off Cirkewwa Point. In my case, with a slight residual anxiety, although the BCD problem had been solved swiftly by one of the divemasters. C took one look at the valve, unscrewed it, fished out the rubber seal and gave it a clean. He then screwed the valve back together and popped down to Suzie’s pool to test it out. Result: one working BCD. I was happy about this, but was also somewhat mindful of the fact that a dive to a wreck which sits at 35m on the seabed isn’t a good place to lose buoyancy. Still, I had faith in C.


Just as well, since I was slightly nervous about this. I’ve recently been getting the scuba yips about diving deep, legacy of a unfortunate incident in the Farne Islands where I overbreathed my reg at 21m and nearly had a panic attack. My best guess is that I’m a little sensitive to the extra work and noise of breathing through the reg at depth. Even with the breathing resistance dialled down, air at 30m is four times as dense as air at the surface, creating extra resistance, and I think it’s that which gives me the yips. 

On the other hand, part of me really, really wanted to do the dive and prove I could do it (and that the ‘Deep Diver’ speciality card I hold isn’t just there to prop up a wobbly table). Malta is where you go to see wrecks, and I really wanted to see this one. And so, along with everyone else, I kitted up and trudged to the entrance point by the lighthouse. As I strapped on my fins and attempted to rinse out my mask in a nearby rock pool without having the tide snatch it out of my hands, I thought to myself, “Wow, that’s a fair way down”. 

Never mind. I stuck the reg in my mouth, inflated the BCD, took a few breath, and giant-strode off the edge to join the others. A quick exchange of hand-signals, and we breathed out, deflated our jackets, and sunk into the sea. At four metres, I tested the BCD with a quick puff of air to slow my descent, turned my head, and watched in happiness as the air failed to stream out of the valve. I kicked forward, then paused, and found myself hanging effortlessly in the water column. 

Problem solved. I set off after the others, keeping pace with my buddy and staying shallow to maximise bottom time. En route, I took a white balance reading from my slate; the camera worked just fine. Five minutes in, the wreck loomed slowly out of the blue, surrounded by fish. 

This was what I’m come to Malta for!

Malta Day 1 – Accidents and Emergencies, Part the Second

We descended gently, or in my case swiftly, to the bottom of the wall nearby and commenced exploring. This should have been a nice, gentle dive with lots of fish and interesting life on the wall to see. 

Except that I still couldn’t swim properly. It felt like I was being pulled downward. Fortunately, we weren’t near a drop-off, but I just couldn’t get buoyant. I filled my jacket, and filled my jacket, and then became aware of a deeply, deeply unwelcome sound behind my head. The sound of escaping air. 

Bugger.

I turned my head as far as I could, and there was the problem; a steady stream of leaking bubbles from the dump valve on my right shoulder. I swiftly signalled my buddy, indicated a problem, wrote on the slate “Leaking valve?” and pointed. My buddy shook her head, possibly because by this point all the air had leaked out and there was either no stream of bubbles, or a very small one. 

We continued our dive for five minutes with me hoping that my buddy was right. Alas, this was not the case. I was having to drag myself across the rocks. I checked my air; down to 110bar from a full 12-litre tank (230). I’d have expected to be at around 180-170 by now, given the depth. At this point, my oh-shit-ometer started going “BEEEEEP” as I stared down at the sea floor, 22m down, and had the deeply uncomfortable thought that if I sunk down to it I might not be able to get back up again on my own without ditching my weights. This was not an irretrievable situation, but it needed dealing with now. Time to end the dive.

I practised a skill I’ve come to realise recently I need more of, that of being assertive with my buddy. I resignalled “Problem”, pointed at the valve, then pointed at the SPG. My buddy, being familiar with my levels of air consumption, realised the problem. We swam off, or in my case lumbered off, to find the rest of the gang. Alas, everyone had swum off in front of us; always a fun situation when you can’t swim fast and you need to catch up to indicate a problem. Ten minutes later, I stationed myself on a rock, whilst my buddy attempted to get the divemasters’ attention. 

I managed to make eye contact with one of them (also, coincidentally, the same instructor who taught me on my Rescue Course). I signalled “Problem” and “Come here”, probably rather emphatically. I then printed on the slate “BCD VALVE LEAKING, CAN’T STAY BUOYANT”. We agreed to swim back together, ascending slowly to about six metres. At this depth the 5mm semidry suit plus the lighter tank and what little air I could keep in the BCD were enough to maintain buoyancy. 

We paddled slowly along, with me keeping a wary eye on my SPG, and trying not to think about the fact that I had no fine control over my buoyancy, and if I went to the surface, no means of keeping myself float apart from my ability to swim, and my semidry suit. (Orally inflating a leaking BCD being an exercise in pointlessness.) I thought about all the functions you need your dive gear to perform both during a routine dive and in an emergency, which you never realise you relying on it to be able to do unless for any reason it can’t do it. 

Nevertheless, we made it uneventfully back to the exit point and paddled back out, trying not to get knocked off our feet by the surf, which was getting up a wee bit. I shed my gear, waited for everyone else to emerge, and started planning a) lunch and b) what on earth I was going to do for the next dive.

Malta Day 1 – Accidents and Emergencies

Recently I spent eight days in Malta, courtesy of my friendly local dive shop, with ten fellow divers. We explored the island and drank much beer.

I'd like to point out that any bugger-ups recounted here are entirely my own fault. No blame attaches to anyone else! So, onward...

The Diving Holiday in Malta team’s first day was spent at Marfa Point, aka Cirkewwa. About an hour’s drive from St Peter’s Bay, it’s where the Gozo ferry leaves from, and also has several excellent dives in its own right. We had our trusty guide to Malta’s diving, penned by Peter Lemon, whom we bumped into in the Dive Shop later in the week. (I’m not being sponsored by him or anything, but if you want a guide to diving in Malta, buy his. It has excellent directions, including compass bearings, good descriptions, and undersea maps that actually make sense when you get under the water.)

Should have been a doddle of a check-out dive, following by an interesting dive on the wreck of the Tugboat Rozi, right? 

Well…

Our first dive was to be around the area known as “Suzie’s Pool”, an area often used for training dives, and thus a logical place to have our first “check-out” dive of the holiday. Always a good idea to test out everyone’s skills and equipment before the more challenging dives. In my case, it was going to be particularly useful, since I had with me my old BCD, which I now use for travelling. The new one is more up-to-date, comfortable and ergonomic, fits over my drysuit, has integrated weight pockets – and also weighs a ton, so it no longer comes with me on holiday unless I have extra baggage allowance. I’d had the old BCD serviced back in February, hadn’t used it since June, and had meant to have a pool dive with it the week before we left, but life got in the way.

I kitted up with 6kg of lead, figuring that since I was wearing the 5mm full-length suit of my two-piece semidry suit – but not the jacket, hood, neoprene socks, 5mm gloves or rash vest that complete the rest of my diving ensemble back in the UK – I could knock 3kg off what I needed. I’d been diving on 6kg in Crete earlier in the year with the same set-up. 

We slithered into Suzie’s Pool, in some cases literally as the sea was vigorously splashing onto the rocks* and swam out to the drop-off. Or in my case, didn’t, as I seemed to be pinned onto the rocks. I signalled my buddy and wrote on the slate I always carry with me: “Too much weight.” 

Looking back, this should have been a clue. Even if 6kg was a little on the heavy side taking into account the amount of neoprene I’d lost from my usual diving set-up, I’ve dived with that BCD on 9kg of lead and a lot more gear, and it can produce roughly 20kg-worth of lift. Even if I was over-weighted, it should have been possible to compensate by adding a bit more air to the jacket.

Still, buddy and the nearby dive leader fiddled about with my weight belt and removed a weight, always an interesting experience when all your weight is on your belt. Fortunately, with only 3 minutes’ dive time and 4m of water above my head, even a buoyant ascent would probably not have done me too much damage. Even more fortunately, this didn’t happen: the dive leader tucked the weight into his BCD pocket, and we set off into the blue.

And then things got worse.
