A group of Dutch students has broken the Guinness World Record for the longest windsurf board ever made and sailed and for the most people on a windsurf board.
The old record dates back to the 1980s, when Toen Joop Nederpelt, Holland's first windsurfer, got a sponsorship from Coca-Cola and produced an 18-meter plank for nine sailors.
More than three decades later, 14 members of the Plankenkoorts Student Windsurf Association decided to improve the previous record set by their colleagues at the Delft University of Technology.
On September 26th, 2015, fourteen boys set sail from Valkenburg Lake in Leiden on a 35.7-meter (117-foot) long windsurf board while their friends took pictures and applauded the intrepid navigators.
Although there were 14 windsurfers connected by wood boards - instead of a single plank - the group successfully managed to sail away.
With more than 500 members, the Plankenkoorts Student Windsurf Association is the largest windsurfing club in the Netherlands.
It was founded in 1981.
