Back-to-Back World Champions: Headcase Retain J/24 World Title
11 November 2026

Howth Yacht Club's Sam O'Byrne and former Club Senior Instructor Cillian Dickson have helped Ireland's Headcase team secure a remarkable second consecutive J/24 World Championship title in Melbourne, Australia. For Howth, the victory represents another proud chapter in a sailing story stretching back more than fifteen years.
The Irish team, skippered by Cillian Dickson, successfully defended the world title they first won in Plymouth in 2025, delivering an outstanding performance at the 2026 J/24 World Championships, hosted by Sandringham Yacht Club on Port Phillip Bay. Competing against 37 other teams from around the world, Headcase entered the final day's racing trailing Australian rivals Checkmate by just two points. However, a superb sequence of first, third and second places in the final three races saw the Irish crew overturn that deficit and claim the championship by an impressive 12-point margin.
The victorious crew of Cillian Dickson, Sam O'Byrne, Ryan Glynn, Louis Mulloy and Marcus Ryan had to demonstrate exceptional consistency, teamwork and determination throughout the championship – sometimes a strong start in a series (2 bullets!) can get the blood flowing a bit too quickly, but these guys kept their cool.

A Journey That Began in Howth
For Howth Yacht Club, this achievement has a particularly special significance. Both Sam and Cillian were members of the Club's original K25 squad, established in 2012 to give talented young sailors an opportunity to develop their skills and compete in serious keelboat racing.
The initiative was driven by a group of enthusiastic Club members, including Noel Davidson, Fergus O'Kelly, Graeme Grant and former Commodore Brian Turvey, who recognised the importance of creating a pathway for young sailors progressing from dinghies into competitive keelboat racing. The programme was made possible through the generosity of Enda O'Coineen, who donated a J/24 to the Club, and the valuable backing of principal sponsor Ireland's Eye Knitwear, together with additional sponsorship from Dave Cullen and Euro Car Parks.
Indeed, there was an early indication of just how much potential this young squad possessed when they won the final race of the 2013 J/24 World Championships, hosted by Howth Yacht Club. Competing against some of the world's most experienced J/24 sailors, the young Howth crew demonstrated that they were already capable of competing with the very best.
It was a stand-out moment for the team involved in the K25 programme, and perhaps the first real sign that these young sailors were destined for great things.
The Club's connection with the J/24 class extends well beyond the K25 programme. Former HYC Commodore Derek Bothwell chaired the organising committees for both the 2011 J/24 European Championships and the 2013 World Championships, two major international events successfully hosted in Howth. Derek remains closely involved with the class in Ireland, regularly officiating as Race Officer at J/24 events around the country.
These championships helped establish Howth as an important venue for international J/24 racing and provided an invaluable opportunity for the Club's emerging young sailors to compete against world-class opposition on their home waters.
That legacy continues today, with Sam and Cillian's latest success providing a wonderful link between the Club's commitment to hosting major championships and its investment in developing young racing talent.
There was also a fascinating coincidence at the opening ceremony of this year's championship in Melbourne. Among those sharing the stage with Cillian Dickson was Australian sailing legend John Bertrand, the man who famously skippered Australia II to victory in the 1983 America's Cup, ending 132 years of American dominance of the trophy. In 2010, he travelled to Ireland to compete in the Etchells World Championship hosted by HYC, memorably winning the title in commanding fashion alongside Andrew Palfrey and a young Tom Slingsby, who would subsequently become one of the most successful sailors of his generation. Sixteen years later, Bertrand was helping welcome the international J/24 fleet to Melbourne, alongside Howth's own Cillian Dickson representing the defending world champions
The latest victory is all the more impressive given the challenging conditions experienced during the championship, with competitors facing everything from strong winds and heavy seas to exceptionally light and shifting breezes. Having made history in 2025 as the first Irish crew to win the J/24 World Championship, Headcase arrived in Australia with the added pressure of defending their title. Cillian said after the final race: “It had a bit of everything, from ridiculously windy and wavy to flat clam – it tested every bit of our abilities” and Sam described it as “an emotional roller coaster!”
They responded in the best possible fashion, winning four races and securing seven podium finishes across the ten-race series, while also claiming the championship's Corinthian title.
For Sam, who has developed into one of Howth's most accomplished young sailors, and Cillian, whose contribution to the Club also included serving as Senior Instructor, this is another extraordinary achievement on the international stage. The Headcase team have already asserted that they are already signed up to the 2027 World Championships in Rochester, New York, but that they will take plenty of time out to enjoy this victory.
The success of Sam and Cillian is a timely reminder of the lasting value of initiatives such as K25, and of the importance of clubs investing in both young sailors and major international events. What began as an ambitious project to introduce young sailors to competitive keelboat racing has helped nurture talent, build friendships and create opportunities extending far beyond Howth.
For the organisers, supporters and sponsors who backed the programme in its early days, there can be few more satisfying outcomes than watching members of that original squad go on to become world champions, not once, but twice.
Everyone at Howth Yacht Club extends their warmest congratulations to Sam, Cillian and the entire Headcase team on their magnificent achievement.
