About us

Matthew Mason

Founder

For Matthew Mason, sailing has always been more than a sport,

it’s a lifelong journey. From the Whitbread Round the World Race to multiple America’s Cup victories, he has spent decades at the

forefront of international sailing.

During the 2003 America’s Cup, Matthew saw a need for a faster, simpler way to connect sheets to sails. That’s when

the T-Clewring was born.

What began as a solution for elite racing is now trusted by sailors everywhere. Whether you’re cruising or chasing the finish line,

T-Clewrings deliver the same reliability and simplicity.
