Infrastructure Works & Slipway Improvements

Thursday, August 22nd, 2019

Infrastructure works at the National Diving & Activity Centre

We have been carrying out some infrastructure works at the National Diving & Activity Centre.

Twenty tonnes of concrete has been laid to extend the lake’s slipway and improve access to and from the water.

We request that visitors keep out of the coned areas until the concrete has dried fully.

We hope this improvement will help our divers access and egress the water a little more easily. Watch this space for further improvements.

Mark Powell at the Rebreather Reunion April 2019

Tuesday, February 26th, 2019

Mark Powell

We are pleased to announce our second guest speaker at Rebreather Reunion 2019 will be Mark Powell.

Mark will be familiar to anyone diving at the National Diving & Activity Centre and is also one of the world’s leading diving instructors. He is a member of the TDI/SDI Training Advisory Panel and an Instructor Trainer Evaluator, the highest rating of instructor.

Deco for Divers

Technical Diving

Mark is the author of Deco for Divers and his new book Technical Diving – An Introduction. In 2010 Mark won the EuroTek ‘Publication of significance Award’ for Deco for Divers and in 2014 was the winner of the Tek Dive USA Media Award.

In 2016 Mark Powell was part of an international team that dived the HMHS Britannic as part of the 100 year commemoration of the sinking. Mark’s talk will cover the history of the Britannic as well as details of its exploration as well as giving an overview of what is required to put together an expedition of this type.

HMHS Britannic was the third and final vessel of the White Star Line’s Olympic class of steamships. She was the fleet mate of both the RMS Olympic and the RMS Titanic and was intended to enter service as a transatlantic passenger liner.

HMHS Britannic is considered the ‘Everest’ of wreck dives. The vessel is the largest passenger ship on the sea floor, followed by Titanic.

Over 100 years have elapsed since Captain Charles Bartlett, standing in his pyjamas on the bridge of the biggest vessel in the world, the HMHS Britannic, gave the call to abandon ship.

It was 8.35am on November 21 1916. The four-funnel ocean liner, built to be even larger and safer than the "unsinkable" Titanic, her ill-fated sister, was listing fast. Bartlett knew the ship was doomed, but on this eerily calm morning as it sailed to collect troops wounded in the first world war’s Galipolli campaign, neither he nor any of his crew could have imagined the speed with which the vessel would go down.

The explosion occurred at 8.12am, sending a giant shudder through the gargantuan vessel, badly damaging its bow as it steamed past the Greek island of Kea. Fifty-five minutes later, the 269-metre (883ft) ship lay on the seabed.

There the Britannic, which was launched in February 1914 at Belfast, and, the following year, put to use as a wartime hospital ship for the first time, would stay at a depth of 122 metres (400ft), untouched and forgotten, until being discovered by the explorer Jacques Cousteau, in 1975.

Today the Britannic lies well preserved in the Aegean. There are many reasons why this is a challenging wreck to dive; the depth of 120m, the problems in getting permissions from the Greek government, the fact it lies in a very busy shipping lane together with all the variations in weather and tides make this a pinnacle dive for anyone.

Rock Works & Out of Bounds Area at Southern End of NDAC Lake

Friday, January 25th, 2019

Rock Stability Works

Rock Stability WorksYou may have noticed recently that we have been carrying out lots of works and improvements around the site.

We’ve spent the last couple of weeks removing debris and carrying out rock stability works on the South-East rock face, under the VIP/Deluxe Wigwams.

This work will continue over the coming months, and for safety, we have placed the water area at the far Southern end out-of-bounds to divers and other water users.

The areas have been buoyed off with orange marker buoys.

 

 

 

 

 

 

 

 

 

 

 

 

24 Hour Scuba Dive – Underwater Marathon in Aid of Headway Brain Injury Charity (16th & 17th September 2017)

Friday, September 1st, 2017

24 Hour Scuba

Two scuba divers who survived devastating brain injuries are to lead a 24-hour underwater scubathon to raise funds for a charity which helps people who have suffered a brain injury.

Members of Cheltenham Sub-Aqua Club, regular visitors to the National Diving & Activity Centre, will work as a relay team to spend a full day underwater led by divers James Neal and Neal Breeden.

Over the weekend 16th & 17th September we will also be holding a demonstration day and raffle with prizes from Apeks, Suunto, Fourth Element, Maxshow, Sea & Sea and Fathom Outdoors. We also have 3 dive computers donated to the NDAC Shop by Suunto where all the money from the sale will go towards the fundraising. There are more prizes to follow and tickets are available from the NDAC shop.

On the demo days we have Liquid SportsMares, SSI , Sea & Sea, TDI, Fourth Element and Maxshow.

Headway Brain Injury CharityJames, 47, a technical diver and instructor from Symonds Yat, in the Wye Valley, suffered a devastating subarachnoid haemorrhage following the rupture of an undiagnosed aneurysm, which led to a grade four bleed on the brain.

Neal, 48, Cheltenham SAC’s secretary also survived a brain injury, after suffering a major stroke nearly ten years ago, in 2008, which left him needing to use a wheelchair.

Now the pair are organising the scubathon in aid of UK brain injury charity Headway, which supported James during his initial recovery. They hope to raise in excess of £5000.

The dive will begin on Saturday 16th September and finish at midday on Sunday 17th September, at the National Diving and Activity Centre in Chepstow.

James says, as well as supporting Headway, he wants to raise awareness of brain injuries and highlight some of the prejudices that go hand in hand with what is described as an ‘invisible disability’.

After he was treated, James, who ran his own business, says all he wanted to do was get back in the water and enjoy scuba diving again. That desire drove his initial rehabilitation.

24 hour scuba challengeHe said: “I was able to return to some level of fitness and get back in the water but I had a great deal of support from my scuba diving friends. Without Cheltenham Sub Aqua Club my life would have become very lonely. I owe them an enormous debt of gratitude.


“I suffered a subarachnoid haemorrhage and whilst I might appear completely recovered on the outside, you can’t and don’t see what I have to deal with, or understand the problems I face, on a daily basis.


“I’m learning to manage my condition but it’s still difficult and I have suffered some horrendous discrimination as a result of people not understanding my disability. But Cheltenham Sub Aqua Club has remained a constant in my post injury life. I don’t know what I would have done without them.


“I suffer terribly from fatigue. Immediately after the injury I was able to stay conscious for perhaps 20 minutes at a time. Now as the day goes on I get more and more fatigued. And there is a huge difference between tiredness and fatigue.


“If you are tired you can keep going. With fatigue you can’t and your body starts to shut down. You become irritable and lose the ability to think straight. Eventually you will lose consciousness. That’s not falling asleep!”

He added: “Brain injuries not only change your life but also your personality. You wake up a different person.”


“If you suffer a head or brain injury it can take a long, long time to recover and in fact you might never recover, at least not fully.

Neal, who worked as an upholsterer before suffering his major stroke when he was just 39, says Headway is an amazing organisation that few people will have heard of.

He said: “When James had his haemorrhage he did experience some real issues from people who just didn’t understand because of their ignorance. People who he thought were his friends turned on him and blatantly discriminated against him. It was horrible to witness, I can’t begin to imagine how it made him feel. Look at a person with crutches or a wheelchair and the disability is obvious. But you can’t easily see a subarachnoid haemorrhage.”


“James and I dive together a great deal and understand each other and our respective limitations in a way perhaps other people don’t. We know what makes each other tick. It’s a very special bond that only  people that have been through what we have could ever really understand.”

He added: “Hopefully we will raise a good deal of money for Headway; the whole club is behind the event. And divers from across the country are supporting us.

Ali Hendley, Manager at Headway Gloucestershire, said the money raised by the underwater scubathon would be very valuable and said: “Giving brain injury survivors the chance to re-learn old skills and develop new ones is what Headway is all about.
