Freediving Comino Wreck: P-31

18/6/2019

0 Comments

 
By David Watson, AIDA & PADI Master Freediver Instructor and Owner & Founder at One Breath Freediving, based in Malta
Freediving in the Maltese Islands has lots of wonderful features that make it spectacular; the stunning underwater visibility of up to 40m, the cliffs and caves that are prevalent across the islands, the deep blue colour of the water that is unique to the Mediterranean Sea. But one thing that really draws freedivers to Malta is the chance to dive on ship wrecks. Malta has a LOT of wrecks, some sunk by nature (storms), by humans (wars), or on purpose to create artificial reefs. The P-31 wreck falls into the latter category.
P-31 History & Key Information:
  • ​A former East German Kondor class mine sweeper built in 1960’s
  • Purchased by Malta in 1992 (along with P-29 & P-30)
  • Decommissioned in 2004
  • Sank 24th August 2009
  • 52m long, 7m wide, weighing 360 tons
Picture
Since being purchased by the Maltese Tourism Authority and sank as an artificial reef attraction for divers, the P-31 now sits upright on the sandy seabed West of Comino( just South of Blue Lagoon and just West of Crystal Lagoon), approximately 200m from shore. The depth on the bottom here is 20m and the top of the wreck is at just 10m deep. In fact the P-31 sits so shallow that it was necessary to cut off the mast of the ship before sinking her so as not to obstruct boat traffic. The wreck can often be seen clearly from the surface when you arrive by boat and I have even seen it occasionally from out of the airplane window when arriving or leaving Malta on certain days! In the summer months you will see a yellow ‘X’ marker buoy above to indicate the wrecks position.
​
Since her sinking, the P-31 has had to weather some rough storms as the prevailing winds on the islands are from a NW direction and sitting this shallow in the water means that waves and swell have had an impact, but considering that she has been underwater for 10 years already the wreck is still in very good condition. Before sinking she was thoroughly cleaned and made safe for divers. This means doors and hatches were removed and obstructions such fixtures, wires and cables were cleared out. There are a number of levels to explore and for a freediver it is normally clear and obvious which direction it is possible and safe to go in.

​Specific Tips for Freediving The P-31 wreck:

  • Be careful of scuba divers! Sometimes there can be large groups of beginners on the wreck and they can block or obstruct exit points. Also, the wall of bubbles they release can hinder the view from a buddies perspective.
  • Check overhead and around you as sometimes there are still a few stray cables or pieces of metal jutting out or hanging loose. Mind not to cut your hands or catch your wetsuit on any sharp edges.
  • The large hatches (what would have been engine compartments) towards the centre and rear of the ship are open and linked together.
  • Surface close to your freediving buoy and display either the ‘diver down’ or ‘alpha’ flag (or both!), to signify that divers are in the water. Ideally, also have someone on the surface watching boat traffic that can warn or issue instructions.

5 Essential Tips for Wreck Freediving:
​
  1. Take a Freediving Course: Knowing how to breathe correctly, having efficient technique, and knowing your body and understanding safety and how to rescue correctly will all make you a better, safer and more confident freediver.
  2. Be a Good Buddy: Always freedive with a buddy, never freedive alone. This is the golden rule of freediving! And, watch your buddies dive attentively from the surface and then meet them at a depth of 10m as they return back to the surface.
  3. Do Your Research: Make a plan before you enter the water and discuss and adapt it during the session when necessary. Know what each other is doing and where you are going. Know the wreck: study photos, ask other divers. Is it safe? Look closely first from the outside and never go in anywhere where there is no clear and obvious exit
  4. Use Suitable Equipment: Use a freediving buoy and rope, that way you can relax and breathe safely before and after the dive, boat traffic can clearly see you, and you can get down to the wreck using Free Immersion and therefore save energy to explore the wreck with a longer bottom time. Also recommend is a torch to look into darker corners and a knife or line cutters in case or accidental entaglement.
  5. Have Fun! Freediving a wreck can be fascinating and exciting with so much to explore and discover. There really is something special about seeing close up some huge manmade structure out of its element and deep in the blue water.

Lastly, please remember, freediving, and especially wreck freediving, can be DANGEROUS. Always freedive with a buddy, never push your limits or enter enclosed spaces with no clear or obvious exit. Please take a freediving course for your own safety and that of your buddy.

Paralenz Camera Pt2: In Water Testing

4/7/2018

1 Comment

 
Those of you following One Breath Freediving on your social media channels will already know that I have been using the Paralenz dive camera quite extensively already, for both photos and videos, so for this review part 2 (part 1 is un-boxing and initial impressions),I wanted to look at it's use in the water. More than numbers such as pixels and frame rates, I wanted to discuss it's functionality and how well it works specifically from a freediver's point of view. 
Picture
Firstly, it's primary mount method that I have employed so far with the Paralenz dive camera has been the mask mount. For me this has been the most convenient as I am normallly using it while teaching or guiding. Once the mask attachment is threaded to the mask strap, you clip the camera on using the 'T-Rail' mount system that gives a reassuring double 'click' when properly secured.

The first thing you notice while wearing it in the water is.....that you don't actually notice the camera! Despite feeling substantial and solid when held in the hand, once attached to the mask I can honestly say that I forget that the camera is actually there. Being so non-intrusive is a huge plus for freedivers as we take in the water minimum equipment and definitely don't like things that create drag or resistance.

Functionality from this position is another massive plus. The feedback loop of vibrations of the camera unit, mean that you do not need to remove the camera (and mask) at all to know what setting you are in! For example, rotate the selector ring clockwise while turned on gives one vibration for video, two vibrations for camera, three for settings etc. And then long or short holds of the activation switch can start or stop recording or offer other functions. This creates a simple user and selector operating system and excellent hands free usability.
Picture
Now lets look at the quality of photos that Paralenz is capable of (for videos, check the OBF YouTube channel). All the snaps in this review were taken from the mask mount position, so just a reach to the side of the head and a short pull on the activation switch can give you some great photos. While primarily a video camera, the photos are surprisingly clear, sharp and lacking in distortion at the edges (as can be common for extremely wide angle cameras). In these photos I had Depth Colour Correction (DCC) turned on and Depth & Temperature overlay turned on. The photo above from 5m displays nice blue water and clear white logos on the wetsuit hood. The first photo handles the reflecting light from the shallow water very well and also created a shot that is not blurred or distorted from the divers movement.
Picture
Initial in water conclusions:
  • Mask mount is very useful for hands free use
  • Unit vibration feedback is a great idea and super useful with mask mount 
  • Photos lack distortion and are very sharp
  • DCC is perfect for multiple depth change diving (such as freediving)
Look out for part three of the test where I will review the features of the Paralenz App.

The Beauty of the Blue Hole

There can't be many places as alluring and iconic to freedivers as the Blue Hole in Dahab. With imposing, barren mountains just metres from deep blue water and a kaliedoscope of colours amongst the corals on the reef with every shape and colour of fish possible, it is a truely beautiful place and draws freedivers from accross the world.
A natural submarine sinkhole, the depth within the hole is 100m and just outside, on the reef's edge, the depth reaches over 1,000m. A sheltered location and lack of current just metres from shore means that this is a wonderful place to train for freediving.
​
One Breath Freediving will be conducting a Training camp in in Dahab Egypt in January and February 2019. Enquire for further information.

The Mammalian Diving Response

The Mammalian Diving Response (MDR)

How the Human Body Responds to Submersion in Water: A Summery
Picture

One of the questions I get asked most frequently as a freediving instructor is about HOW we can hold our breath longer. What is the 'trick', the 'secret' that can make it easier for us to be underwater deeper or longer. What many people don't realise is the the human body already holds most of the answers!

Here is an overview of the four main diving responses of the human body, collectively known as 'Mammalian Diving Response' (MDR):

Peripheral Vasoconstriction
Trigger: Breath-holding, facial immersion in water, increased pressure
Response: Blood vessels in the extremities of the body (arms, legs) constrict to keep blood prioritised for the vital organs of the body
FACT: A disadvantage of reduced blood flow is increased carbon dioxide and lactic acid build up, but tolerance to these can be increased through training

Bradycardia
Trigger: Facial Immersion in (cold) water, breath-holding
Response: Heart rate slows down by 10-25% in untrained, or up to 50% in trained freedivers, thus conserving blood Oxygen
FACT: In diving seals, heart rate has been measured going from 125bpm to below 10bpm during a dive!


Spleen Effect
Trigger: Breath holding and increased pressure on repetitive deep dives
Response: The spleen contracts and releases more red blood cells which aid oxygen transportation in the blood
FACT: The spleen is not an essential organ, but holds a reserve of blood and is important as part of the bodies immune system


Blood Shift
Trigger: Increased pressure on deeper dives
Response: Blood plasma swells the alveoli of the lungs filling the chest cavity area to prevent barotrauma injury from increased pressure at depth
FACT: Only as recently as the 1970's did scientists begin to understand this phenomenon once divers such as Enzo Maiorca returned from 50m+ dives, injury free!
