Virtual ISORA Waypoints & Tracker Managed Finish Line for Holyhead–Dun Laoghaire Race

Virtual ISORA Waypoints & Tracker Managed Finish Line for Holyhead–Dun Laoghaire Race

In view of the light wind forecast this weekend ISORA are making provisions for a finish outside Dublin Bay for its fourth race of the series from Holyhead to Dun Laoghaire tomorrow. ISORA will also be using virtual waypoints for the 50–mile race.

The forecast appears to be no deterrent as a bumper fleet of 29 has confirmed for the Irish Sea duel. The ISORA fleet nearly broke the 30–boat ceiling except for two unavoidable last minute pull–outs this morning.

The reason behind a Kish light as opposed to a Pier finish is that it is envisaged that there will be no wind in the bay when the fleet arrives late tomorrow afternoon.

The tracker managed finish line – between North Kish and Kish light will give accurate crossing times to within approx five seconds. Is this is the first time an offshore race has been 100% finished using technology alone?

Howth's Dux Wins First ISORA Race from Dun Laoghaire to Wicklow Buoy

Howth's Dux Wins First ISORA Race from Dun Laoghaire to Wicklow Buoy

#isora – The arrival of three Howth Yacht Club boats onto the ISORA scene this season has produced immediate results with HYC entry Dux, an X302 yacht skippered by Anthony Gore-Grimes winning the first ISORA race from Dún Laoghaire to Arklow on Saturday. 

Although the strong winds and big seas cancelled most of the local inshore racing for Dublin Bay Sailing Club (DBSC), the 15–offshore yachts came to the line off Dun Laoghaire's East pier in what was some of the strongest breezes of the day. Dux followed by top performing J109 Ruth (Liam Shanahan of the National Yacht Club) made the best of the 40 – knot southerly winds that saw a number of retirals on the upwind leg along the Dublin and Wicklow coasts. Conditions dictated a shortened course to the Wicklow outfall buoy instead of North Arklow, a reduced distance of some 38 miles instead of 50 that produced an early (and welcome) high speed reaching leg back to Dublin Bay.

The provisional results for Race 1a - the Dún Laoghaire day race (incorporating the first Royal Alfred Yacht Club Coastal Series) is available to download below as a jpeg file.

In a move that has drawn the international support of ISAF's offshore working party, the ISORA crews are experimenting with iphone navigation during the race and 'virtual marks' to adjust the courses. 

In deploying the new mobile technology ISORA has teamed up with app developer 'Predict Wind Tracker'. 

Unfortunately on Saturday, ISORA did not get to use them to full effect. The weather was so awful that the basis of the course was to keep as close to land as possible but away from banks and headlands.

This, says Peter Ryan of ISORA, is a cost effective method of recording any offshore race that can be viewed live and also replayed after the event. ISAF's David Brunskill has offered to judge any issues surrounding the use of the virtual marks.

Ryan adds that if the innovative approach to setting courses is successful, 'it will radically change offshore racing to the betterment of all', a sentiment supported by the world sailing body.

The next race is the Holyhead to Dún Laoghaire qualifying race on 10th May. This is followed by the return race from Dún Laoghaire to Holyhead on 24th May. One of the highlights of the ISORA series this year is the Midnight Race from Liverpool to Douglas on 6th June.

New Race From Conwy Features in 2012 ISORA Calendar

New Race From Conwy Features in 2012 ISORA Calendar
#ISORA – A sailing race from Conwy in Wales is a new addition to the 2012 Irish Sea Offshore (ISORA) calendar agreed at the weekend that features virtual waypoints for the first time.

It was agreed that virtual marks would be in fixed positions on a trial basis. ISORA Commodore Peter Ryan believes it will 'revolutionise' offshore racing in the Irish Sea and produce better and more exciting racing.

It was also agreed at the weekend's agm at the National Yacht Club in Dun Laoghaire that there would be two "Restricted / Silver Fleet" classes. The decision of what boats qualify for these classes will be made by the Sailing Committee prior to the first race. It is hoped that this will allow a fairer spread of prizes.

Dublin Bay

Dublin Bay on the east coast of Ireland stretches over seven kilometres, from Howth Head on its northern tip to Dalkey Island in the south. It's a place most Dubliners simply take for granted, and one of the capital's least visited places. But there's more going on out there than you'd imagine.

The biggest boating centre is at Dun Laoghaire Harbour on the Bay's south shore that is home to over 1,500 pleasure craft, four waterfront yacht clubs and Ireland's largest marina.

The bay is rather shallow with many sandbanks and rocky outcrops, and was notorious in the past for shipwrecks, especially when the wind was from the east. Until modern times, many ships and their passengers were lost along the treacherous coastline from Howth to Dun Laoghaire, less than a kilometre from shore.

The Bay is a C-shaped inlet of the Irish Sea and is about 10 kilometres wide along its north-south base, and 7 km in length to its apex at the centre of the city of Dublin; stretching from Howth Head in the north to Dalkey Point in the south. North Bull Island is situated in the northwest part of the bay, where one of two major inshore sandbanks lie, and features a 5 km long sandy beach, Dollymount Strand, fronting an internationally recognised wildfowl reserve. Many of the rivers of Dublin reach the Irish Sea at Dublin Bay: the River Liffey, with the River Dodder flow received less than 1 km inland, River Tolka, and various smaller rivers and streams.

Dublin Bay FAQs

There are approximately ten beaches and bathing spots around Dublin Bay: Dollymount Strand; Forty Foot Bathing Place; Half Moon bathing spot; Merrion Strand; Bull Wall; Sandycove Beach; Sandymount Strand; Seapoint; Shelley Banks; Sutton, Burrow Beach

There are slipways on the north side of Dublin Bay at Clontarf, Sutton and on the southside at Dun Laoghaire Harbour, and in Dalkey at Coliemore and Bulloch Harbours.

Dublin Bay is administered by a number of Government Departments, three local authorities and several statutory agencies. Dublin Port Company is in charge of navigation on the Bay.

Dublin Bay is approximately 70 sq kilometres or 7,000 hectares. The Bay is about 10 kilometres wide along its north-south base, and seven km in length east-west to its peak at the centre of the city of Dublin; stretching from Howth Head in the north to Dalkey Point in the south.

Dun Laoghaire Harbour on the southside of the Bay has an East and West Pier, each one kilometre long; this is one of the largest human-made harbours in the world. There also piers or walls at the entrance to the River Liffey at Dublin city known as the Great North and South Walls. Other harbours on the Bay include Bulloch Harbour and Coliemore Harbours both at Dalkey.

There are two marinas on Dublin Bay. Ireland's largest marina with over 800 berths is on the southern shore at Dun Laoghaire Harbour. The other is at Poolbeg Yacht and Boat Club on the River Liffey close to Dublin City.

Car and passenger Ferries operate from Dublin Port to the UK, Isle of Man and France. A passenger ferry operates from Dun Laoghaire Harbour to Howth as well as providing tourist voyages around the bay.

Dublin Bay has two Islands. Bull Island at Clontarf and Dalkey Island on the southern shore of the Bay.

The River Liffey flows through Dublin city and into the Bay. Its tributaries include the River Dodder, the River Poddle and the River Camac.

Dollymount, Burrow and Seapoint beaches

Approximately 1,500 boats from small dinghies to motorboats to ocean-going yachts. The vast majority, over 1,000, are moored at Dun Laoghaire Harbour which is Ireland's boating capital.

In 1981, UNESCO recognised the importance of Dublin Bay by designating North Bull Island as a Biosphere because of its rare and internationally important habitats and species of wildlife. To support sustainable development, UNESCO’s concept of a Biosphere has evolved to include not just areas of ecological value but also the areas around them and the communities that live and work within these areas. There have since been additional international and national designations, covering much of Dublin Bay, to ensure the protection of its water quality and biodiversity. To fulfil these broader management aims for the ecosystem, the Biosphere was expanded in 2015. The Biosphere now covers Dublin Bay, reflecting its significant environmental, economic, cultural and tourism importance, and extends to over 300km² to include the bay, the shore and nearby residential areas.

On the Southside at Dun Laoghaire, there is the National Yacht Club, Royal St. George Yacht Club, Royal Irish Yacht Club and Dun Laoghaire Motor Yacht Club as well as Dublin Bay Sailing Club. In the city centre, there is Poolbeg Yacht and Boat Club. On the Northside of Dublin, there is Clontarf Yacht and Boat Club and Sutton Dinghy Club. While not on Dublin Bay, Howth Yacht Club is the major north Dublin Sailing centre.
