World Sailing, the sport's international governing body, has signed up Musto, the English outdoor clothing brand, as its official clothing partner.
The agreement runs to the end of 2025, with international race officials responsible for governing the sport on the water at global events to wear Musto clothing at World Sailing events.
In addition, the World Sailing team will wear Musto at the delayed Tokyo 2020 and Paris 2024 Olympic Games.
David Graham, chief executive of World Sailing, said: "Musto was an obvious choice for World Sailing's official clothing partner due to their long and successful legacy in sailing. We are delighted to be partnering with them.
"Their pace of change and innovation is impressive. Our sport is evolving very quickly with much faster boats which puts a greater demand on the kit we wear. Musto have responded quickly, enabling the sailors to focus on performing.
"World Sailing has ambitious sustainability goals and it was hugely important that Musto are pioneering in this space in their industry. The partnership covers the depth and breadth of our sport, which will enable us to collaborate on many levels and in turn grow global participation."
Nick Houchin, head of marketing at Musto, added: "Our partnership with World Sailing is the umbrella under which everything sits, allowing us to create brand advocacy by engaging the global sailing community from grassroots to Olympic level.
"This partnership cements our position as the sailing world's leading performance clothing brand and will support our global growth ambitions. Now we are the official clothing partner of sailing's governing body, we are looking forward to communicating and working with a truly global audience."
