Over 300 sailors will compete in Dublin Bay in seven different classes (Laser Radial, Laser 4.7, 420, Feva, Topper, SL16 and Optimist). For youth sailors, this event is the most important in the annual calendar as it is the decider for the top Irish sailors to compete internationally during 2011 and is the pathway for future Olympic sailors. Podcast with Olympic Team Manager James O'Callaghan here.

The 420 fleet is already in situ as the Leinster Championships were held over Easter and the girls team Emma Geary and Niamh Connolly won the event in style. This team is the only 420 crew to qualify internationally for a place on the Irish team to compete in the ISAF Youth Worlds in Zadar, Croatia and will be looking to win next weekend to secure this honour.

Dublin Bay will host the 2012 ISAF Youth World Championships and this year's ISA Mitsubishi Youth National event is an important test event with representatives from the international sailing authority visiting Dun Laoghaire to view plans and test logistics.

In addition to the 420 fleet the Laser radial fleet will also be competing to qualify to represent Ireland in Croatia. Philip Doran aged 17 from Courtown in Wexford is the current former under 17 World Champion in the Laser Radial fleet although the National title has eluded him so far. In the girls fleet it will be a toss up between Saskia Tidey (RIYC) and Sophie Murphy (Quoile YC) as both already have a national title each under their belts.

The younger Optimist fleet is also celebrating this week after two top 5 positions at the Easter Regatta in Braassemermeer, the Netherlands. In fact an Irish team has competed at this event for 23 years and this is the first time that Ireland has won the country prize. Sean Donnelly from Dun Laoghaire who finished fourth in Braassemermeer is also leading the Optimist fleet in the trials and will be anxious to hold on to first position during the ISA Mitsubishi Youth Nationals.

In other fleets, the laser 4.7 fleet is enjoying record numbers with many ex-Optimist and Topper sailors choosing this boat. Finn Lynch from Blessington and Seafra Guilfoyle from Cork will be firm favourites to win the class.

Overall Dublin Bay will be a spectacle of sail over the May Bank holiday weekend with light winds forecast.

Mitsubishi Motors have been a proud supporter of junior sailing in Ireland for the last 7 years. In recent years Ireland has had successes at youth level with winner of the girls under 21 Laser World Championships and a top 10 at the 2010 ISAF Youth Worlds and wins at the British National Optimist Championships.

Royal Cork's Peter O'Leary and his stand in German crew Frithjof Kleen are 13th overall after two races in the Skandia Sail for Gold regatta at Weymouth. O'Leary's rival for the Irish Star nomination at the Olympic regatta in two years time fared less well in the opening breezy rounds; Max Treacy and Anthony Shanks lie 33rd in the 36-boat fleet. There is a three way battle for Irish honours in the 91-boat Women's Laser Radial. In the qualifying rounds Annalise Murphy is racing in the blue fleet. Tiffany Brien and Saskia Tidey are both in the yellow flight. Northern Irleland's James Espey and Chris Penney are coming to terms with a full on Olympic Laser fleet of 180 boats. Full results HERE. Video at the end of this post.

It cannot have been an easy decision for the triple Olympic gold medalist, Ben Ainslie, to return to the Finn class at Skandia Sail for Gold 2010. Ainslie completely dominated the Finn, unbeaten between 2004 and 2008, winning gold medals at both the bookending Olympic regattas. Ainslie was the man who put the bite into Dennis Connor's book title, 'No Excuse to Lose'.

But right now, Ainslie has every excuse to lose; preoccupied with Team Origin campaigns in the TP52, the Louis Vuitton Trophy and the World Match Racing Tour, not to mention the little matter of being eight kilograms under his fighting weight. But an ISAF Sailing World Cup regatta at home, at the venue of the 2012 Games? How could he not compete? How could he not win? But how could he win, after so long out of the boat? Dilemma...

But Ainslie was taking it all in his stride this afternoon, "It's funny because this morning I was talking to my coach about my goals for the week, and we laughed because normally we wouldn't worry, I just want to be at the top! It is a very different week for me, because it's not about where I place, it's about rejoining the Finn fleet, seeing how it has progressed and learning about the conditions in Weymouth." And perhaps unsurprisingly, after a shaky first race, Ainslie was right back in the hunt for the second, and finished fourth for the day. Watch this space.

Things went less smoothly for his barely-less-gilded tactician at Team Origin, the double Olympic gold medalist, Iain Percy, and his crew, Andrew Simpson. They were also returning to the boat after a lay-off due to duties with Team Origin – although not such a long one, they are the reigning Star World Champions. But they broke a forestay before the first race, and had to come ashore to fix it, returning to the line two minutes after everyone else had started the second race - eventually finishing 21st. Simpson said afterwards, "Realistically you can't predict a forestay break like we had today, there is just an element of bad luck involved in these things but it's part of the game. But we went out there afterwards, we fought back and managed to take back 17 places."

The Star fleet was dominated by two more America's Cup sailors, Hamish Pepper and Craig Monk – the Kiwi duo won both races, an awesome performance in a fleet of this class. But elsewhere, things went better for Skandia Team GBR, with Nic Asher and Elliot Willis sharing the lead in the 470 Men with French duo Pierre Leboucher and Vincent Garos.

Other stand-out performances belong to Udo Hessels and Mischa Rossen in the Sonar class with two bullets. While in the 49er, Frenchmen Manu Dyen and Stephane Christidis scored two seconds. Jonathan Lobert (FRA)  scored a first and a second in the Finn class, while both Marit Bouwmeester (NED) and Veronika Fenclova (CZE) won their two races in their respective Laser Radial fleets to be joint top.

Ben Ainslie

"I really enjoyed it today, we had some great racing even though the conditions were pretty tough for me at my current weight. But I am pleased with how it went and pleased to be racing in the Finn again and to be back at Weymouth.

"It's funny because this morning I was talking to my coach about my goals for the week, and we laughed because normally we wouldn't worry, I just want to be at the top! It is a very different week for me, because it's not about where I place, it's about rejoining the Finn fleet, seeing how it has progressed and learning about the conditions in Weymouth.

"I don't feel any pressure this week. I haven't raced for two years. And I think that having been through so much at the Olympics it's a different feeling. Of course, you want to do well for everyone who supports you, but the biggest pressure always comes from your own desire to succeed.

"There is a lot of good talent in the UK, and it will be tough to qualify. But hopefully that will make us push each other that much harder, so that if I do qualify I am in a much stronger place."

Andrew Simpson

"Realistically you can't predict a forestay break like we had today, there is just an element of bad luck involved in these things but it's part of the game. But we went out there afterwards, we fought back and managed to take back 17 places overall".

"We haven't sailed together that much since Beijing, so we are holding back slightly at the moment. We have competed here before, and we are just enjoying the event, but we will have to ramp it up at the end of the week".

"I think because we have sailed together a lot before, the communication on the boat is good, sailing the boat again is like putting on an old pair of shoes, they still fit - we just have to readjust them a bit. It looks like for this event we will have to work on the breezier stuff".

"All of the foreign competitors here are trying to learn as much as they can about the venue before 2012, just as much as we are. Obviously we're based here, so we will spend the next 18 months working out the wind and getting the boat just right. A medal at 2012 is definitely possible for us, we wouldn't compete if it wasn't. But we will have to work hard and put in the hours on the water."
