The first person to experience travel to both outer space and the deepest part of the sea will be the subject of an exclusive Irish interview with Pat Kenny tomorrow, Thursday 23 July.

As previously reported on Afloat.ie, oceanographer and former Nasa astronaut Kathy Sullivan already made history as the first woman spacewalker in 1984.

But she doubled that achievement last month when she became the first woman to reach Challenger Deep — the deepest-known part of the world’s oceans at 35,810 feet below the surface.

As opposite as these two missions may seem, however, they both come from Sullivan’s passion to understand the world around her as much as possible.

Sullivan — who was also interviewed by Lorna Siggins for the Sunday Times this past weekend — will talk making history, exploring the frontiers of our world and more with Pat Kenny tomorrow, Thursday 23 July, as part of the Marine Institute’s Oceans of Learnings series.

The interview will be streamed live on the Marine Institute’s channels on Facebook, Twitter and YouTube from 2pm Irish time (or 9am EST in the US).

Broadcaster Pat Kenny has confirmed he'll financially support Dalkey residents in their challenge against a mixed-use development for Bulloch Harbour.

In recent days, householders around Dalkey have received a newsletter asking residents to contribute to a fund-raising initiative.

This is aimed at raising sufficient funds to launch a High Court judicial review of June’s An Bord Pleanála ruling.

Yesterday Dalkey resident Mr Kenny said that he intends to make “a good donation” to the fund-raising effort by the Bulloch Harbour Preservation Association.

“Everyone is being asked to chip in to get the process going,” he said.

“I am no legal expert, but it was a wrong-headed decision made to grant planning permission and it has to be stopped.

#LobsterFestival – Dalkey's Lobster Festival (23,24 and 25 August) is for the second time, to welcome visitors to experience and enjoy the crab and all that Jazz!, writes Jehan Ashmore.

The south Dublin Bay coastal town, once the principle port for Dublin during medieval times, is to be a fusion of local seafood and a gathering of the best of current global jazz musicians, plus fun free events for all the family.

Among the musicians will be Sharon Shannon who performs on the opening day of the festival (23 August). For details on how to win a pair of tickets, check out the festival's facebook page below.

Not forgetting!... the King of Dalkey... long live the King! who is making a comeback.

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.

There could be anything up to 500-boats afloat for events right across the bay and out in to the Irish Sea.

Joining the 390 boat DBSC fleet for its 128th season is a gathering of over 300 dinghies in Dun Laoghaire for the Mitsubishi Youth National Championships at the Royal St. George and National Yacht Clubs. It's an important event because it is a dry run for next year's ISAF Youth Worlds on Dublin Bay.

The National Yacht Club is also host for the first race of the 2011 ISORA offshore season. Up to 17 starters from a possible ISORA entry list of 40 are confirmed for the first race to Holyhead. First gun for ISORA is at 0755. An Early one!

Across the bay in Howth there is a competitive fleet assembled for the SB3 Eastern Championships. A notable feature of the event is the inclusion of Olympic campaigner Annalise Murphy.

Ashore, Réalt na Mara Dun Laoghaire RNLI's new D-class lifeboat is to be officially named during a ceremony on the East Pier in Dun Laoghaire this Saturday at 12 noon. The lifeboat is to be named by Mr and Mrs Pat and Kathy Kenny. RTE presenter Pat Kenny and his wife Kathy have been long-standing supporters of the Dun Laoghaire RNLI lifeboats.

Mid week forecasts show good sailing winds for the weekend. Met Eireann is forecasting Southeast to east force 2 to 4 breezes, light enough for a gentle start to the season but there's still a chance of stronger for Saturday afternoon. Listen to Eddie English's weather prediction from Cork Harbour.
