#Diving - Diving with an oxygen tank might soon be a thing of the past thanks to a new material that could allow divers to breathe underwater without bulky gear.

According to Discovery News, the crystalline material is made from cobalt and acts like a sponge, sucking up oxygen from the air - or water - around it and releasing it when needed.

The so-called 'Aquaman crystal' is being researched by scientists at the University of Southern Denmark, who explain that just a few grains of the substance contain enough oxygen for one breath.

"As the material can absorb oxygen from the water around the diver and supply the diver with it, the diver will not need to bring more than these few grains," said Prof Christine McKenzie.

But the revolutionary new material has applications beyond diving, such as in medicine for patients who require oxygen tanks to assist their breathing.

The Irish Cruiser Racing Association (ICRA) Information

The creation of the Irish Cruiser Racing Association (ICRA) began in a very low key way in the autumn of 2002 with an exploratory meeting between Denis Kiely, Jim Donegan and Fintan Cairns in the Granville Hotel in Waterford, and the first conference was held in February 2003 in Kilkenny.

While numbers of cruiser-racers were large, their specific locations were widespread, but there was simply no denying the numerical strength and majority power of the Cork-Dublin axis. To get what was then a very novel concept up and running, this strength of numbers had to be acknowledged, and the first National Championship in 2003 reflected this, as it was staged in Howth.

ICRA was run by a dedicated group of volunteers each of whom brought their special talents to the organisation. Jim Donegan, the elder statesman, was so much more interested in the wellbeing of the new organisation than in personal advancement that he insisted on Fintan Cairns being the first Commodore, while the distinguished Cork sailor was more than content to be Vice Commodore.

ICRA National Championships

Initially, the highlight of the ICRA season was the National Championship, which is essentially self-limiting, as it is restricted to boats which have or would be eligible for an IRC Rating. Boats not actually rated but eligible were catered for by ICRA’s ace number-cruncher Denis Kiely, who took Ireland’s long-established native rating system ECHO to new heights, thereby providing for extra entries which brought fleet numbers at most annual national championships to comfortably above the hundred mark, particularly at the height of the boom years.
