#twitterbuoy – Up to the minute information on the progress of the 39,000 mile Volvo Ocean Race – headed for Galway in three weeks time – will be "tweeted" to millions around the world from a high tech "Twitter Buoy" which will "go live" in Galway Bay.

The Galway 'Twitter' Buoy was launched by the Irish Lights Vessel "Granuaile"  as previously reported by Afloat.ie at a location close to Mutton Island and will transmit a constant flow of data on the race, the weather conditions being experienced by the sailors and other ocean and meteorological data.

The Galway 'Twitter' Buoy will be accessible on Twitter @Galwaybuoy. Its information stream will also be passed onwards through Facebook and the Internet. It will transmit from today until mid July.

The launch of the service – a Volvo Ocean Race first - has come about through a collaboration between the Commissioners of Irish Lights, the Marine Institute, Techworks Marine, Smartbay Ireland and IMERC partners, (Irish Maritime and Energy Resource Cluster).

The eight metres high navigational buoy is fitted with multiple environmental sensors and electronic transceivers including AIS (Automatic Identification system) and RACON (Radar beacon) and will 'tweet' the whereabouts of the Volvo boats as they head for the nail biting Race Finale in Galway.

#LECTURES – Pádraig Laffan will present his lecture on 'Dublin Bay and the Kish Light' next Tuesday (20th March) starting at 8pm in the Foxrock Parish Centre. The Co. Dublin venue is located at the rear of the R.C. Church.

All are welcome to the lecture (admission €3) which is part of a monthly held talks programme run by the Foxrock Local History Club. For further information visit www.foxrocklocalhistory.ie/page7.html

Crew kitted in similarly bright orange coloured sea safety-survival suits entered the lifeboat before it plunged into the water. The activity was observed through the binocular-scope which overlooks Coliemore Harbour with excellent views across the sound to Dalkey Island, Dublin Bay and Howth Peninsula.

The binocular-scope does not require payment to operate and was unveiled in 2008 in memory of local resident the late Dr. John de Courcy Ireland, the 'father' of maritime Ireland (to read more click HERE). He was for 26 years a honorary secretary of the local RNLI station in Dun Laoghaire and a staunch campaigner of Irish maritime affairs.

Each Monday a routine lifeboat practice is conducted by the 47ft Trent class ALB (all-weather lifeboat) RNLB Anna Livia (info and PHOTO). Last night's drill also involved the new D-class ILB (inshore lifeboat) RNLB Réalt na Mara which was named earlier this year by Kathy Kenny, wife of RTE presenter Pat Kenny.

Under the cover of darkness the crew of the ILB Realt na Mara simulated an 'injured casualty' on the island where the casualty was prepared to be taken off by stretcher from the island's small harbour. From there the casualty was transferred to the larger RNLB Anna Livia which lay offshore. During the exercise, powerful searchlight beams from the ALB provided essential light to assist in the transfer operation.

Asides the lifeboats, there is plenty of wildlife to observe on the rocky outcrops at Maiden Rock, Clare Rock and Lamb Island, which forms the second largest island after the main island of 22-acres, where a resident herd of goats have been part of the local community for over 200 years.

As for the South Korean built Cumbrian Fisher, she too has close connections with these waters as she was named in Dublin Port in 2005. She is a frequent caller to Dublin bringing bulk liquid products from the oil refinery in Milford Haven, Pembrokeshire which is a major supplier, serving the demands of the capital.

Dublin Port has two oil jetties which cater for four tankers, where bitumen, chemicals, liquid petroleum gases, molasses and oil are handled on a 41-hectare zone with storage for 330,000 product tonnes to include 6,000 tonnes of LPG. In addition aviation fuel is frequently delivered to the terminal to satisfy the constant demand for aircraft using Dublin Airport.

Cumbrian Fisher alongside her sister Clyde Fisher where built for James Fisher & Sons and in recent years they have tended to take anchorage off Dalkey Island and off the Nose of Howth. In comparison the vast majority of vessels anchor in Dublin Bay which is divided into quadrants for the purposes of anchorage allocation.

Before the completion of the South Wall in Dublin Port, which considerably improved safer access of vessels entering the River Liffey, it was the relative deeper and sheltered waters of Dalkey Sound which were used instead as Dalkey acted as the principle port for Dublin between 14-17th centuries.

Vessels would convey cargoes which were taken to and fro by lighter to the coast where it was carried by horse and cart to nearby Dalkey before onward travel across the exposed plains to Dublin City.

To learn more about Dalkey's medieval maritime heritage with its relationship with the capital of Dublin in addition the use of Dalkey Quarry in the construction of (Kingstown) Dun Laoghaire Harbour, visit the Dalkey Castle & Heritage Centre.  To read more go to www.dalkeycastle.com in addition to further information about Dalkey including the local community council newsletters click HERE.

Regular guided tours will provide a fascinating insight into the work of the Commissioners of Irish Lights (CIL). The tours (first-come basis) are also available for disabled access and they start from 12 noon to 5pm, noting the last tour is 4.30pm. Location: Harbour Road, Dún Laoghaire.

Like most of the tours and events in Open House Dublin, there is no pre-booking required. Entry is FREE and on a first-come basis. For more information about what to expect from your tour or event, check the How It Works by clicking HERE.

CIL operate the 79m aids-to-navigation tender ILV Granuaile which is based at her homeport of Dun Laoghaire. The 2,625grt tender was built by the Dutch Damen Shipyard group in Galati, Romania. She was then towed to The Netherlands where further outfitting work was conducted. She entered service in 2000 and she is the third tender to be named after the Mayo pirate queen.

Occasionally ILV Granuaile can be seen moored alongside the berth adjacant to the marine depot accessed through Dun Laoghaire Marina, though she mostly calls to the harbour's western bight area, using her DP (dynamic-positioning) mode. Her design is ideally suited for buoy and chain work, search and rescue, salvage and recovery, towing, hydrographic applications, and ROV work.

She is shallow drafted at 4.4m and has heavy lifting equipment including a 20 tonne aft-mounted crane with an outreach of 20m. Accommodation is for a crew of 16 in addition there are cabins for a further 10 persons.

Courtown Harbour Rowing Club took second place in a time of 3:3:19 and third place honours went to Stella Maris Rowing Club with a time of 3:16.00. The hosts of the Hobblers Challenge, St. Michaels Rowing Club based out of the Coal Harbour, passed under the high walls of the East Pier Lighthouse and battery some two minutes later in fourth place.

The annual event (for race-route click HERE) was only re-introduced onto the race calendar last year after a break of several years. The skiffs were launched at the Coal Harbour slipway where they headed over to line-up for the starter's gun opposite the Hobbler's Memorial located on the publicly accessible Eastern Breakwater which is between the Stena Line HSS fast-ferry berth and the Dun Laoghaire Marina.

In attendance to greet the start of the race in memorial of the Dublin Bay hobblers was the RNLB Anna Livia of the local RNLI lifeboat station. The bronze memorial depicts a tower of lifejackets in commemoration of three young Dun Laoghaire hobblers who after piloting and unloading the schooner Jealous of Me in Ringsend, failed to return home.

This occupation was carried out by men also from Ringsend, Dalkey and other harbours and it was the first crew to reach a ship and throw a hook on the deck who would win the business of pilotage and unloading in Dublin Port.

Crews would think nothing of rowing out to the Kish Bank on the hope of spotting a ship. If they waited offshore and no passing trade appeared along the East Coast the craft doubled as a bed if it became too late to row home. The craft were much larger and heavier compared to the present day skiff and it is in these oarstrokes that the Hobblers Challenge follows the original race of the hobblers during the 18th and 19th centuries.

It was apt that on the same day of this year's Hobblers Challenge, the 107-year-old ketch Bessie Ellen, a former cargo-carrying vessel that represented one of the last such sail-trading ships operating in the Irish Sea, was making a passage to the east of the Kish Bank.

The decommissioned Codling Bank (Lanby) buoy is no longer in the water but rests firmly on a quayside in Dublin Port, writes Jehan Ashmore. In late July  the Commissioners of Irish Lights withdrew the Lanby (Large Automated Navigation Buoy) was towed by the tender ILV Granuaile to the Coal Quay where the Lanby was hoisted out of the water.

The Lanby neighbours the adjacant Hammond Lane Company which is due to demolish the structure for scrapping. The removal of the Lanby, the last to serve in Irish waters, completes the withdrawal of Major Floating Aids to Navigation (MFAs) that also consisted of Lightships.

The Lanby was replaced with a Type 1 buoy to mark the Codling Bank offshore of Arklow. The new aids to navigation buoy has a focal in excess of 5-metres is fitted with a racon and Automatic Identification System (AIS).

Apart from loading scrap-metal the Coal Quay is also used by vessels for dry-cargoes trades such as animal feed, re-cycled glass and fertiliser.
