Around 2,000 sailors from throughout the world have gathered in Crosshaven in Cork Harbour to compete in Volvo Cork Week.
The biennial sailing regatta is taking place for the first time in four years, due to Covid-19 restrictions in 2020.
Sailors from as far away as the United States and Hong Kong are back in the picturesque village of Crosshaven, home to the Royal Cork Yacht Club.
Sailing conditions so far have not been at their best, but sunshine is keeping everyone happy.
Michael Wilson from the Isle of Mann travelled to Cork Week to race his boat, Shotgunn, in the Cape 31 class.
"We first came here 20 years ago to race Cork Week and it's good to be back," he said as he prepared to head out for a day's racing.
Amelie Sayers is a member of the crew on board the yacht Erin which, in spite of the name, sails out of Monaco in the south of France. Erin is a classic yacht - one of the head turners in Crosshaven this week.
"I am from Monaco, and I am lucky enough to be sailing on Erin all week long," Amelie said. "I am very, very excited to sail her. It's a bit of Monaco in Ireland this week."
Cork Week is also a huge week for Irish sailors. It's very competitive, but its success is down to its reputation for fun.
The local welcome and the quality of racing are what attracts so many sailors to Cork Week, according to co-chair and Vice Admiral of the Royal Cork Yacht Club, Anna Marie Fegan.
"We have almost 2,000 people doing what they love and then coming in and socialising in the evening together. It's just marvellous to see friends back together again," Anna Marie told RTÉ News.
Cork Week is estimated to be worth 6.5 million euro to the local economy, drawing crowds of more than 10,000 to Crosshaven, including spectators.
"It's huge for the local economy," Anna Marie said. "We have accommodation [booked] everywhere.
"People are eating; they are drinking; they are seeing the beautiful countryside. And, of course, this weather is putting us in this most incredible scene. It's fabulous."
The Royal Cork Yacht Club - the oldest yacht club in the world - did not get to celebrate its tricentenary in 2020 due to Covid restrictions.
Celebrations and racing this week continue until Friday.
