Unifiber Tendon Join Windsurf Raceboard UF Essentials 

Low-Profile Precision for Proteus and Phantom Boards

Built for speed, control, and compatibility, the Raceboard UF Essentials Tendon Joint is the go-to solution for Unifiber Proteus V1 & V2 and Starboard Phantom models (2021+). The low-profile design brings your rig closer to the board, helping you close the gap and stay locked in across the course.

At the heart of the system is a high-grade TPU tendon, secured with two oversized custom bolts for quick, easy replacement without risk of over-tightening. A solid stainless-steel U-pin provides a secure mast connection built to last season after season—while weighing around 50g less than most alternatives.

A precision-shaped nylon pad ensures smooth glide over the mast track, securely locking into the carriage without sacrificing fluid movement.

And for peace of mind during every session, a Spectra safety rope rated to 650 kg connects the top and bottom—ready for anything the race throws your way.

Why racers choose it:

• Direct connection = faster reaction + better “gap closing”
• Compatible with Unifiber Proteus and Starboard Phantom (2021+)
• Super light without sacrificing strength
• Safe, simple, and easy to maintain
