Small blue balls found on a North Dublin beach have prompted concerns around their origin and whether they pose a threat to a protected habitat, as the Irish Times reports.

Brian Bolger — who lives near Bull Island — says he has reported increasing numbers of the 25mm rubber-like spheres, both blue and orange, washing up on the island’s Dollymount Strand.

“We thought they were golf ball innards because there are two courses on the island,” he says.

But he later discovered that similar objects washed on an English beach were traced back to a nearby nuclear power station.

Those objects, known as Taprogge balls, are used in the cleaning process for cooling systems in power stations and other industrial processes.

It’s not yet confirmed if the balls found on Dollymount are of the same type, but their presence within the Dublin Bay Biopshere prompts concern for their potential to affect a sensitive habitat for many marine wildlife species.

The Dublin Bay Biosphere Youth Committee is holding a ‘Monster Clean-Up’ on North Bull Island this Sunday 27 October from 2pm.

Get into the spooky spirit in this Hallowe’en-themed coastal litter pick-up event, and all taking part will be entered into a prize draw to win a family pass to Dublin Zoo.

All ages are welcome to join in — especially in costume — with all equipment provided as well as hot drinks for what will probably be a chilly day on Dublin Bay.

About the TP52 Racing Yacht

The TP52 racing yacht is a remarkable example of cutting-edge technology in the world of competitive yachting. Measuring 52 feet (15.85 metres) in length, this vessel is constructed entirely from carbon fibre, making it an incredibly light and agile craft.

The TP52 features a 6.25-metre high rig, complete with a fractional asymmetrical spinnaker and a self-tacking jib. This design reduces the workload of the crew, allowing for more efficient manoeuvres and freeing up the crew to focus on the mainsheet upwind and on two-sail reaches.

The spinnaker rigging set-up, measuring 15.00 m2, presents a challenge to even the most experienced crews, requiring them to be fit and perfectly coordinated. Maneuvering the boat requires athleticism due to the vessel's lack of inherent stability and the high speed generated by the fully battened mainsail and jib.

The TP52's hull is constructed of fibreglass-reinforced polyester in a foam sandwich layout, resulting in a weight of just 74kg. The fully battened mainsail and jib are made from a transparent Mylar laminate with orange or red Dacron trimming, while the spinnaker is manufactured from ripstop Nylon.

The mast is made up of three parts, featuring an aluminium bottom and middle section, with a polyester-fibreglass composite tip to increase mast bend and decrease overall weight. The capsizing moment, which can be generated by a heavy mast tip, is also reduced through this design. The TP52's foils are constructed from either aluminium or fibreglass, depending on the specific requirements of the vessel.

Overall, the TP52 racing yacht is an exceptional example of the latest advancements in yacht design and technology. Its lightweight construction, advanced rigging, and high-speed capabilities make it a top contender in the world of competitive yachting, challenging even the most skilled and experienced crews.
