Responsible diving during a drought part 1: Your dive gear

It is no secret that Cape Town is a little low on water. The coastal dive industry, even though we spend a lot of time in the ocean, is actually quite a heavy user of fresh water. Everything thing you learn about taking care of your equipment revolves around the phrase “rinse well with clean water.” Clearly this is not an option in Cape Town at the moment

So how do you maintain your dive gear and keep it in safe condition during such circumstances? For a dive centre or training facility the volume of gear that needs cleaning can be overwhelming at the end of the day. Here are a few suggestions on how to manage.

No matter how well you de-kit after a shore dive, wet dive gear tends to collect sand. (You can minimise this by using something like the Wetsac, but this isn’t always an option with my students.) I take the gear back into the ocean and rinse it as well as I can in the shallows. This involves several trips as wet dive gear is heavy.

Wetsuits are rugged and don’t too much mind being left salty. They do end up being a little crispy after a while, but the most important, non-negotiable aspect is hygiene. I take a spray bottle with a mixture of Savlon or Dettol and spray the inside of the salty wet suit, then let it dry. Gloves, booties, hoodies and rash vests get the same treatment.

Regulators get a similar treatment, without the disinfectant. I give them an overall light spray with warm water in a spray bottle, with a good spray into the mouth piece. The inflator hose nipple also needs to be rinsed well as this does not handle salt build-up too well and could get stuck during a dive (at best, annoying… at worst, life-threatening).

Cameras, dive computers, torches and compasses do need a little more care, but fortunately are relatively small and have lesser water requirements. I use a narrow, tall bucket and put the bucket in the shower. While showering you can easily catch enough water to cover these items…. Seldom more than a litre is required, and you can leave them to soak.

The biggest challenge is a BCD. Again, it is a tough and rugged piece of gear, but the inflator mechanism does not like salt build up. Using the same bucket of water used for the camera and dive computers, I soak the inflators overnight. I then connect an airline and inflate and deflate the BCD to help flush out the valves behind the inflate/deflate buttons.

Whilst such basic, minimalistic care for your dive gear is not as thorough as that recommended by the manufacturer, it is a method of extending the use of your gear when the availability of fresh water is close to zero. As a rule I prefer to only have two students per class and can effectively wash three sets of gear in less than three litres of water.

It goes without saying that as soon as it rains, you should be collecting that water to give your gear the long, luxurious soak it deserves (and probably needs by that stage)!

Genius gear: the Wetsac

Using the WetSac
Using the WetSac

Several years ago the wonderful Tami gave me a WETSAC for my birthday. It sounds like something squishy and perhaps offensive, but in fact it is a marvel of ingenuity and designed to improve the lives of divers and surfers and outdoorsmen everywhere. She bought it at a craft market in Hout Bay, and both of us have been hunting for a retailer of this product since then. Recently, I struck it lucky with a well phrased google search (something like “wet bag”).

How many times have you struggled out of your wetsuit on a rough surface (Miller’s Point parking area and Hout Bay harbour, I’m looking at you), hurting your feet, standing on the neoprene and pressing it into the tar? You’re damaging yourself and your gear! Then you toss the dripping, smelly wetsuit into the back of your car – into a box, if you’re organised – and hope it doesn’t spray seawater and bits of grit from the parking area everywhere while you drive home.

WETSAC is here to help. Essentially a mat that converts into a waterproof bag, it comprises a circular piece of tough fabric with a drawstring around the edge. You stand on it to get out of your suit, throw in your gloves, hoodie and booties, then step off and pull the drawstring tight. Toss the bag into your divemobile and don’t worry about remnants of your diving and changing adventures ending up all over the boot. It is beyond convenient. Plus, you can buy it online. Make a note for next Christmas!

(I was not compensated in any way for this post… The thing is just geninuely nifty!)

Newsletter: All aboard!

Hi divers

Summer winds are fading and winter winds are slowly starting to arrive. The visibility of the Atlantic sites drops off and the water in False bay gets cleaner and cleaner as if pumped through a filter. A whole new range of creatures start to make an appearance while other creatures hide somewhere warmer. There are still several giant short tail stingrays hanging around at Miller’s Point, where the fishing boats drop the fish guts overboard near the slipway.

Many people feel it’s too cold to dive in winter… It is cold for sure, but with the right gear and on the right days, winter diving in Cape Town beats anything summer can come up with. Currently False Bay is clean and the temperature is around  15-16 degrees. By adding a shorty, decent gloves and a thicker hoodie you are all set. Dry suits, or damp suits as I call them, do also work, when they work. I don’t sell gear but I am very happy to give advice on whether a deal is a deal or a rip off!

Sevengill cowshark

We had fair conditions last weekend and dived with the sevengill cowsharks (thanks to Tamsyn again for the awesome photo!) and the seals on Sunday. It was surgy and the viz wasn’t the best but Shark Alley was swarming with sharks. Unfortunately the seals didn’t want to come and play because of the swell. Fortunately the reef around Partridge Point is stunning! The wind has been north and west a few days this week and the visibility has improved.

Weekend plans

As for the weekend – tomorrow looks the best, but Saturday could work for one launch to Tivoli Pinnacles or an early double tank dive to Atlantis and Outer Castle.  The wind comes up very strongly around lunchtime so we want to be out of the water early. Sunday will be wetter on the surface than it will below so I guess it’s a stay at home and watch Formula 1 instead.

As usual text me if you want to dive tomorrow or on Saturday. We are really looking forward to our Durban trip on 17 June, which is getting closer. There is still space on this trip and our Red Sea liveaboard trip in October, so give it some thought and let me know if you want more information.

One of the divers on the boat two weeks ago took this video of the seal we saw at the slipway. Keep watching right to the end!

New gloves (again)!

It seems like yesterday that I was proudly waving about a new pair of blue Seac Sub gloves. Something like 120 dives later, and they’re in quite bad shape… Some of the fingers have punched through, and the seams along the side of my wrist split recently. Boat diving off a rubber duck, towing a reel and camera work are quite hard on gloves, and there’s quite a high attrition rate in the Lindeque household.

Enter the new pair of Seac Sub gloves that Andre supplied me with in the middle of November. They’re 3.5 millimetres thick and seal at the wrist with a velcro strap. The seams around the two middle fingers ensure that flexing and dextrous work is comfortable (as comfortable as it can be in thick gloves!). I’ve tested them in the Atlantic and so far so good. I am rather fond of the Seac Sub brand, and my BCD is also theirs.

The old blue pair have been glued, and now live in the “glove box” for students to borrow.

Guess the dive gear

I often take pictures by accident. This is no mystery – the construction of my camera housing and the fact that I sometimes forget to turn it off on exiting the ocean conspire here to produce curious results. What is a mystery, however, is what some of the photos depict. As a fun (haha) activity for our loyal reader(s), here’s a game of Guess the Dive Gear. Answers at the end of the post…

Fantastic Trilastic

I’ve been wearing a fantastic new wetsuit for the last few months: the Mares Trilastic 8-6-5. Like Tony’s Mares Flexa 8-6-5, the Trilastic (which is just from the new range) is 8 millimetres thick on the torso, 6mm on the upper arms and thighs, and 5mm on the forearms and calves. The one I have is from the She Dives line by Mares, which makes allowances for women’s body shapes.

With it I wear a loose hoodie, and my booties and gloves go over the bottom of the wetsuit ankles and wrists, not underneath. There are two reasons for this:

  1. The Trilastic doesn’t have zips on the legs and arms
  2. The wrist, neck and leg seals are kind of special and seal very tightly against my skin (except for the neck seal)

The wrist and ankle seals don’t have zips and are quite delicate. Wearing the booties over the leg seals involves a bit of gymnastic stretching to get the zips closed, but it results in warm water trapped very effectively inside the wetsuit and boots. Unfortunately it makes me look extremely bulgy after a dive because the water can’t escape, but it keeps me warm!

I like the small zip at the front – it makes a big difference to my experience of seasickness, since my old ScubaPro presses very uncomfortably on that little dip at the bottom of one’s neck. This contributes greatly to the urge to hurl! There’s still fabric touching on my neck, but not nearly as firmly or tightly as a wetsuit with just a back zipper. I actually wanted a wetsuit with a front zip, but in the thickness I wanted (i.e. VERY) there wasn’t anything available for ladies.

With it I have a 0.5 millimetre thick Mares Rash Guard. It’s very warm but I do find the stitching a bit coarse and I have to be careful how I line the seams up on my arms and torso. The wetsuit seals so tightly that after some dives, however, my arms even have dry patches on them. I slather vaseline on the skin in the front of my neck before repetitive dives, because I get an uncomfortable chafe going on there if I spend a day in my wetsuit and rash vest.

The sleeves of both the wetsuit and rash vest are a bit long (or perhaps my complaint should be that I have short arms). I suppose I can have them adjusted (might be cheaper to do the sleeves rather than the arms). In the mean time I make use of Gerard’s patented plastic bag donning technique for wetsuits.

I can still wear a shortie on top of the 8-6-5. It remains to be seen whether Atlantic diving will require this.

A very scientific experiment

Thermometer
Thermometer

The idea for this experiment was born after a few dives Tony did last year, wearing his dodgy old wetsuit, in very cold water. He’d emerge from the water almost paralysed, unable to speak, shivering uncontrollably. His muscles would cramp, and he’d struggle to breathe for a time. It’d take him quite a long while afterwards to regain his comfort level.

We wondered just how much a lengthy submersion in cold water affects one’s body temperature when wearing a wetsuit (two 5 millimetre layers, plus a hoodie and gloves). I’ve been trying to remember to take a thermometer with me to dives for months, and finally – on the day of two planned dives in False Bay in early February – managed to remember to pack it into my bag.

Since Tony is now diving in a drysuit on deeper dives, the person whose temperature was to be measured was yours truly. I don’t get as cold as he does – I have more body fat, for one thing, and for another I learned to dive in the Cape and haven’t dived much anywhere else… So cold water is the norm for me. I’m also a hot sleeper, if that counts for anything – my body is quite good at warming itself!

Anyway, I took my temperature before and after both dives. My thermometer isn’t terribly reliable so I took a couple of readings each time and averaged them. Temperatures are in degrees celcius. It was a beautiful, sunny day with a warm breeze. The air temperature was about 26 degrees. Here are the results:

Time Description Temperature
0630 Leaving home for Miller’s Point 36.5
0800 Just before first launch to the SAS Transvaal 36.6
0937 Five minutes after surfacing, dive time 32 minutes, depth 32.4 metres, water temperature 8 degrees celcius 35.0
1040 Second launch to Partridge Point 36.1
1201 Five minutes after surfacing, dive time 38 minutes, depth 21.9 metres, water temperature 8 degrees celcius 34.8

For those of you (like me) who enjoy graphs, here’s one showing the same data.

Graph of body temperature before and after repeated dives
Graph of body temperature before and after repeated dives

We repeated this experiment on two dives of similar duration and similar temperature in the Atlantic ocean, and the results were also a 1.5 degree drop in body temperature which had almost fully reversed itself by an hour after the dive. We’re also going to repeat this experiment on my husband, in his drysuit, to see whether the temperature changes are as extreme. I know they’re not – this time on the boat ride back to the slipway it was me whose teeth were chattering so much I couldn’t eat my Bar One, while Tony displayed a complete lack of sympathy, all snug in his drysuit pyjamas!
