#SPEED - The World Speed Sailing Records Council has confirmed two new world records set by Paul Larsen's Vestas Sailrocket 2 last month.

As previously reported on Afloat.ie, the Weymouth-based sailor and his crew claimed an average speed over over 59 knots with a peak of 63.5 knots on the 500-metre run on Namibia's Skeleton Coast using the purposely designed hydrofoil.

Their speed smashes the previous record of 55.65 knots set by kitesurfer Rob Douglas in the 2010 Luderitz Speed Challenge.

But not content to rest on their laurels, two days later they did it again - raising the bar for the fastest nautical mile along the same stretch of coastline by more than 5 knots, and taking the accolade held by Alain Thébault's Hydroptère since 2009.

For Larsen, the confirmation is vindication for more than a decade spent chasing 'the perfect reach'.

Two days after finally smashing the Outright world speed sailing record, the Vestas Sailrocket 2 team decide to tackle the 'Nautical Mile' world record which was held by the mighty 'Hydroptere'. It was always going to be an interesting challenge for the VSR2 team as the speed course that they sail on in Walvis Bay, Namibia is defined by a beach which is exactly 1.04 miles long. This requires them to launch the boat out in more exposed waters and try and get up to as high a speed as they dare in rough water before they hit the start of the mile. At the end of the course they also fire out into rough water and have to bring the boat to a stop. It's hard on the boat. The beach is not straight but has a slight curve in it .

The mile is measured by TRIMBLE GPS equipment in a straight line so pilot Paul Larsen needs to balance between sailing in close to the beach for the flat water... and sailing the straightest and hence shortest distance between A and B. In this run, with winds that averaged just under 25 knots, The team smashed not only the nautical mile record* by over 5 knots averaging over 55.3 knots... but also raised their own 'Outright speed' record* to 59.38 knots over 500 meters hitting a peak speed of 64.78 knots (74.55 mph, 120 kph).

For Larsen it was the perfect payback for 10 years chasing 'the perfect reach'. Speed sailing had paid him back in full and a dream was realised.

VSR2 performed exactly as predicted by the Sailrocket design team of Malcolm Barnsley and Chris Hornzee Jones at AEROTROPE. The spec for the boat was to be able to hit 65 knots in 26 knots of wind in order to average around 60 knots.

From the Vestas Sailrocket 2 team in Namibia on Saturday:

Well the big forecast is playing out. It's 1017 here and the wind is already in. Our little corner of the Walvis Bay Yacht Club is buzzing as we prepare for the big day that we know lies ahead.

This is the first big wind day we have had in over 6 weeks now.

Today we focus purely on taking the outright record over 60 knots.

The project has been going on a big up for some time now and we want it to continue that way. Things can easily go the other way. The day is going to pump. We used to try and use that power to punch through our glass ceilings but now we have shown that we don't need it. We are operating at around 2.4-2.5 times windspeed and a few more knots makes a big difference. The thing is that whilst we know we will have a lot more power if it's gusting up to 30... what we don't know is what the nature of our drag curve is up ahead. Is it gradual or is it another 'brick wall'. On paper we expect cavitation to happen just over 65 knots. That's on paper. How it manifests itself is yet to be seen.

This boat is damned powerful and in 30 knots, sheeted in hard with around 65-70 knots of apparent wind it's going to be one hell of a tug of war between the wing and the foil. VSR2 is being optimised for a big number. The pitch of the main foil has been reduced by 0.25 degrees, fairings have been added to the front of the stub beam (which holds the foil) and the outboard flap that controls the height of the leeward float has had its negative pitch range increased to help me keep it all on the level.

Later that day: Fresh off the TRIMBLE... 68.01 over 1 second, 65.45 over 500 meters.

And on Sunday: On the GT-31 gps 67.74 and an average 500m 65.37! Yihaaaaaaaaaa...

#SPEED RECORD - Weymouth-based sailor Paul Larsen and his crew have laid claim to a new world record in speed sailing, as BBC News reports.

The team say they achieved an average speed of over 59 knots - with a peak of 63.5 knots - on a half-kilometer run at Namibia's Skeleton Coast using their purposely designed Vestas Sailrocket 2.

Their speed "smashed" the previous record of 55.65 knots set by kitesurfer Rob Douglas in the 2010 Luderitz Speed Challenge, although it is yet to be confirmed by the World Speed Sailing Records Council.

It was the culmination of 10 years' hard work on the part of Australian-born Larsen and his team, using the specially adapted design built on the Isle of Wight - a vessel that's "very impractical in conventional sailing terms", as Larsen told the Times.

He added: "We are buzzing — no-one has done this with a sailing boat before... This shows how unique and revolutionary the boat is.

"We’ve had to break the boundaries of sailing — like the equivalent of our sound barrier — just over 50 knots."

The boat's designer Chris Hornzee-Jones said the vessel - inspired by the success of speed sailing kitesurfers and windsurfers like Oisín can Gelderen - was key to their breakthrough.

"It is designed to be an ideal testing platform for trialling new foil concepts which will allow us to break through this 'glass ceiling' and perform at speeds well over 60 knots.”

#WINDSURFING - Oisín van Gelderen is all but confirmed as Irish Speed Sailing Champion for the second year running.

His national record speed (44.23 knots by 5x10 second average and 43.96 knots over 500m) puts him far ahead of his nearest competition in the rankings.

But his competitive spirit would not let him rest on his laurels.

"Ever since setting that record in February, I have been trying to beat it," he said, "and we had a really good day on Thursday in Dungarvan."

Though he did not beat his averages, he did set a new Irish record for peak speed at 47.89 knots (verification pending).

Van Gelderen dedicated his previous national title win to to the memory of Surfdock founder Alan Harris and Irish 500m speed record holder John Kenny, who both passed away in 2010.

Meanwhile, his Surfdock teammate Noelle Doran has taken the women's title for 2011 with a very impressive set of times for the year.

Her Irish women's peak record of 38.17 knots was complemented by third overall place for 2011 by 5x10 second average and first in the world over 500m.

"I'm so delighted for her," said Van Gelderen. "She had a nasty injury a few years ago, where she dislocated her hip while windsurfing. The resulting nerve damage put a stop to her competing in Waves and Freestyle, where she had multiple national titles."

For most involved in conventional stick and cloth boating, the 49er dinghy is the ultimate speed machine. Its description as 'the high performance class' at the Olympic regatta gives it that ultimate status. Before you watch the vid below tho, ask yourself what's fastest: Moth, kiteboard or 49er.....choose carefully before clicking play on this (strong language) video!

Oisín van Gelderen has won the Irish Speed Sailing Championship for 2010 after a phenomenal season.
The Afloat.ie/Irish Independent Sailor of the Month for September 2010 had a clean slate of results for the year, posting the fastest speeds over 500m and by 10-second average.
But the highlight of his year was undoubtedly his personal record-breaking speed trials in West Kirby, near Liverpool (SEE VIDEO BELOW) where he reached a maximum speed of 47.17 knots (87.36 kmph).
"I am looking forward to 2011, and hope to improve my speeds, and spend a lot
more time back in the waves this year too," he said.

Dublin windsurfer Oisin Van Gelderen has an anxious wait for verification that he broke the Irish Speed Sailing record yesterday.

"I know for sure my Max Speed of 47.17 knots is the fastest any Irish sailor has ever done" he claims.

The current record, approved by the World Speed Sailing Council, was set by John Kenny in February who achieved a personal best of a burst of 45.3 knots (it's 84 kph) and averaged 42.52 for the 500 metres.

Van Gelderen describes the build up to yesterday's record attempt at the UK's West Kirby venue:

"The wind was pretty strong - 30-40 knots, so I rigged my brand new Pryde 4.7m RSRacing - just to get the hang things. As it turned out, this sail was perfect for me all day (I'm not the heaviest speed-sailor at 78 kgs).

I knew my board was already fast, but I'm also delighted with the sail, which was rigged for the first time and performed straight away without any tuning.

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.
