Anna Burnet and John Gimson are among Great Britain’s most decorated mixed multihull sailors, having established themselves as a dominant force in the Nacra 17 class. The Olympic silver medalists (Tokyo 2020) and multi-time World Champions have consistently defined elite performance on the water—most recently competing at the Paris 2024 Olympic Games before celebrating their marriage later that year.
Over the past few years, Anna and John have worked closely with us to develop and test the new CL290 Titanium Trapeze Cleat, which is now in full production.
Engineered from titanium with no moving parts, this aerodynamic, ultralight cleat weighs just 21g and measures only 46mm in length—slashing both size and weight by nearly 50% compared to conventional trapeze cleats.

The 21-boat Nacra 17 fleet raced a nine-race series with one discard. Due to a lack of wind, no final series was held. John and Anna dominated from the start. By the midpoint of the regatta, they had secured four race wins and a ten-point lead, never looking back.
“We are really happy to take the win at Kiel Week. We had plenty of light winds, which meant a lot of movement on the trapeze. It was exciting to be racing with the new titanium cleats—they're beautifully smooth to use and perfect for keeping the drag and weight down,” explained Anna Burnet, who, along with John Gimson, was the driving force behind developing the new CL290 Titanium Trapeze cleat.
The Clamcleat® CL290 Titanium Trapeze cleat and handle are designed for ultimate pro sailors. Engineered from titanium with no moving parts, this aerodynamic, lightweight trapeze cleat weighs only 21g and is just 46mm in length—reducing its size and weight by nearly 50% compared to conventional trapeze cleats. Designed for use with composite trapeze lines, the top section's halo ring design allows for extra grip, meaning sailors with strong hands may not even need the low-profile aerodynamic handle. For sailors who require extra surface area for a secure two-finger grip during constant adjustments, ergonomic handles are available. Aerodynamics were a critical part of the design, specifically optimizing airflow across both the side of the cleat when trapezing and the back of the cleat on the leeward side.

The adjustable harness line CL289Kit/R features two wrap-around webbing straps: one with a tube-covered rope loop and another with an aluminium insert cleat for easy height adjustment. The design transfers the wing's load through your body core, reducing arm fatigue, whilst the cleat's position minimizes damage risk during wipe-outs. The cleat's moulded body ensures minimal weight with aluminium insert teeth to maximise load capacity and wear resistance.

If you've visited us at our trade shows, you've probably gone home with one of these cleats! Here's how the tool was made.

Ocean Bound Plastic (OBP) is abandoned plastic waste within 50 km of coastlines or waterways in areas with poor waste management. It accounts for about 80% of plastic marine litter and poses a high risk of entering the ocean.. OBP is collected and recycled into usable material. As our current stock of cards run low, we'll replace them with OBP material, identifiable by "Made from 100% recycled plastic". For more details on OBP material, please contact us.

This clip is secured to the main body with a blue lanyard. Available now. Underground recycling and refuse systems, often called 'iceberg bins,' are high-capacity waste management solutions with most storage hidden beneath the pavement. Only a small, modern-looking disposal pillar is visible at street level.
