The Unifiber Baseplate Tendon Joint HD (U-Pin) V2 is built for maximum durability, safety, and everyday practicality in demanding windsurf conditions.

Its heavy-duty construction integrates stainless steel components throughout, creating a continuous and reliable connection between board and rig, even if plastic parts wear over time. The high-quality TPU tendon is secured with oversized bolts for durability and easy replacement.

Quick release system (Chinook-style)

The standout feature of this baseplate is its smart quick-release system:

• A push button locks two internal sliding pins
• Pressing the button releases the tendon joint from the base
• The baseplate stays attached to the board
• Only the upper section (tendon + U-Pin) is removed

This Chinook-style solution allows:

• faster transport without unscrewing the base
• reduced wear on the board thread
• easier handling in sandy or cold conditions

In practice, you can keep the base mounted on your board inside the bag and disconnect your rig in seconds.

The EVA-covered disk improves grip on the board, while the Spectra safety rope connects the upper and lower sections with a breaking load of up to 650 kg, ensuring maximum safety even in case of tendon failure.

A perfect choice for riders looking for maximum strength combined with real-world usability.
