Ros an Mhíl/Rossaveal could become a hub for marine renewable energy projects, if plans by Údarás na Gaeltachta come to fruition.

The board of the Gaeltacht authority has recently approved funding to plan the development of a 30-acre site it owns near the Connemara harbour.

Údarás na Gaeltachta says its study will include a review of the marine renewable energy sector and its potential opportunities, as well as “the requirements and advantages that Ros an Mhíl harbour and Gaeltacht companies have to meet future demands and to benefit from same”.

The organisation says renewable energy will be central to its 2021-2025 strategy, which is set for publication early next year, adding that Ros an Mhíl “has been long identified by Údarás na Gaeltachta as a strategic resource”.

Chair of the board Anna Ní Ghallachair said: “We are happy that Údarás na Gaeltachta will be in a position to undertake this study on the opportunities for renewable energy in the Ros an Mhíl area.

“This is a strategic sector for Údarás, and indeed for the whole country. If we are to halt climate change, we must avail of all opportunities there are to generate clean energy.”

Údarás na Gaeltachta hopes to issue tenders on etenders in the weeks ahead so that work can commence early in the new year.

The news comes after similar moves have been mooted for the Shannon Estuary, while in Cork a new strategic partnership aims to improve communication with the wider marine community as the pace of offshore wind farm development picks up.

#OpenHydro- A French naval defence and energy-company, DCNS, has agreed a €130 million investment in OpenHydro, an Irish hydro-power firm.

The Paris-based giant, which among its activiities includes building submarines, yesterday outlined its expansion plans for OpenHydro, a tech company developing marine power alternatives.

As part of the deal DCNS will extend its stake in OpenHydro from 11 per cent to a controlling 59.7 per cent, subject to regulatory approval. To read more on this story, The Irish Times has a report.

The Star keelboat is a 6.9 metres (23 ft) one-design racing keelboat for two people designed by Francis Sweisguth in 1910.

The Star was an Olympic keelboat class from 1932 through to 2012, the last year keelboats appeared at the Summer Olympics at which Ireland's representatives were Peter O'Leary and David Burrows.

Ireland has performed well in the class internationally thanks to some Olympic campaigns including a bronze medal at the Star World Championships in 2000, won by Mark Mansfield and David O'Brien.

The boat is sloop-rigged, with a mainsail larger in proportional size than any other boat of its length. Unlike most modern racing boats, it does not use a spinnaker when sailing downwind. Instead, when running downwind a whisker pole is used to hold the jib out to windward for correct wind flow.

Early Stars were built from wood, but modern boats are of fibreglass and carbon construction.

The boat must weigh at least 671 kg (1,479 lb) with a maximum total sail area of 26.5 m2 (285 sq ft).

The Star class pioneered an unusual circular boom vang track, which allows the vang to effectively hold the boom down even when the boom is turned far outboard on a downwind run.

Another notable aspect of Star sailing is the extreme hiking position adopted by the crew and at times the helmsman, who normally use a harness to help hang low off the windward side of the boat with only their lower legs inside.
