New British National Records set in Freediving

Published

British National Records set in the new Depth Discipline Constant Weight Bi-Fins by Dean Chaouche & Helena Bourdillon!

British freedivers Dean Chaouche and Helena Bourdillon have set new national records of 98m and 75m respectively, in the constant weight bi-fins (CWTB) depth category.  The discipline has been recently recognised by AIDA International, whereby a diver descends using only bi-fins as propulsion. Dean and Helena are the first UK athletes to set records in this discipline.

This is the first time Helena has set a national record in freediving, and she set two over the course of just two days!  The first of the two British records took place on 4 August when she swam down to 73m, the next day, 5 August, she went to 75m, both times at the Caribbean Cup Freediving Competition.  Helena had this to say:  “I’m thrilled to have done this and enjoyed it a lot!

Dean set the first of four CWTB records at the Asian Freediving Cup on 9 June, going down to 90m; he went two meters deeper on 24 August at the Korean Cup organised by Freedive Panglao in the Philippines and then to 95m on 29 August and finally to 98m on 31 August at the Freedive Panglao Mini Comp.

Dean said: “After my 90m bi-fins dive which I had made earlier in the year I was surprised by how much fun deep bi-fins dives can be and so I decided that I would push the depth a little more and enjoy the process of developing a new discipline.  My other goal for these string of comps, organised by Freedive Panglao, was to achieve a greater state of relaxation similar to what I feel on training dives and to build slowly. I began with a 92m dive on the second day of the Korean Cup, following that dive I decided to go for 95m on day one of the Mini Comp, it was a very relaxed and enjoyable dive, exactly the experience I was looking for.”

“I made a slightly more challenging dive to 98m due to current, though I am very happy with the numbers, what I’m more happy about is the circumstances and the quality of dives and focus.  There was quite a bit of current all the way down, I was aware of this before my dive but I still maintained a very relaxed state of mind.  When I started the dive I could feel it was taking more energy to keep straight and I could feel the current moving me around on the descent but I realised I was still in a very comfortable state of mind and knew that I could make the dive even with the added difficulty.  The swim up was for sure harder than the previous dive but ultimately successful and a clean protocol. I’m super stoked with how relaxed I can feel even in competition and will aim to build on these satisfying dives.”

Dean Chaouche from Swansea has broken several national records in both the free immersion and constant weight no fins depth disciplines and is currently ranked in the world’s top 5.  You can follow Dean on Social Media under the handle @deanfreediver.  Helena Bourdillon is a motivational speaker as well as a competitive freediver and is based in London.

Book Review: Shells of the World

Shells of the World: A Natural History by M.G. Harasewych

Shells of the world is a guide to the world of marine, shelled molluscs. And what a varied and interesting world it is. Some of my favourite things to find on a dive are detailed in this book, including disco clams (or Electric File Clams as they are correctly names), the cephalopods, giant clams and sea hares. There are also many on my wish list, top of which is the Nautilus.

Each chapter provides a detailed description of the species, along with beautiful images. You can dive deeper and discover where they live, both with global distribution and the habitat they prefer. Learn about their diet, reproduction and diversity.

Having dipped in and out of this lovely book over the past few weeks, it has inspired me to learn more about this group of animals that we see on most divers, wherever we are in the world. Some of the shells are incredibly intricate and beautiful. I have always agreed with never collecting, or touching, marine life. The description of a certain set of cone shells should be a warning to those that are happy to pick up marine life! One of the cone shells has a local name called the cigarette snail. Why? Because once the venom is in your system from this animal, you only have time to smoke one cigarette before the affects of the venom are fatal!

What the publisher says:

Mollusks are invertebrate animals with a remarkable natural history and a rich fossil record, and their shells are prized for their breathtaking variety and exquisite beauty. Shells of the World provides a wide-ranging look at the incredible diversity of marine mollusks. An informative introduction outlines the lineages covered, followed by a directory section, split into classes, that profiles a broad selection of different taxa to give a sense of their sheer numbers and variety.

  • Features hundreds of beautiful color photos, depicting both the live animals and their shells
  • Discusses mollusk evolution, anatomy, life cycles, behavior, and ecology
  • Describes unique characteristics, distribution, habitat, and size
  • Provides valuable insights into the conservation of the world’s marine mollusks
  • Ideal for malacologists and shell collectors everywhere

M. G. Harasewych is research zoologist emeritus and former curator in the Department of Invertebrate Zoology at the Smithsonian Institution’s National Museum of Natural History. A fellow of the American Association for the Advancement of Science, he is the author (with Fabio Moretzsohn) of The Book of Shells: A Life-Size Guide to Identifying and Classifying Six Hundred Seashells.
