Tendon Joint Raceboard UNI Essentials (U-Pin)
Universal. Race-Ready Design.
The Raceboard UNI Essentials Tendon Joint is your dependable link to performance—built for the Exocet RS 380 and compatible with most raceboards on the market. With a low-profile design, it brings your rig closer to the deck for a more direct feel and improved race stance.
The TPU tendon is built for durability and comfort, secured with two large custom bolts that allow for quick tendon swaps without damaging threads or over-tightening. The single-piece stainless steel U-pin adds bombproof strength while shaving grams for overall efficiency—roughly 50g lighter than other raceboard joints.
A premium nylon pad sits underneath to glide effortlessly over your mast track without losing locking security, while a 650 kg-rated Spectra safety rope connects the top and bottom for critical backup.
Why it wins on the water:
- Ultra-low profile improves race positioning and rig response
- Universal fit for Exocet and most raceboards
- Stainless-steel U-pin for long-term reliability
- Lightweight, durable, and built for real-world racing
Regular inspection of your baseplate is crucial for safety and performance.
Here's what you need to check before hitting the water:
Power/Boge Joint Inspection:
- Check rubber for deterioration, cuts, or drying
- Look for splitting at top/bottom sections
- Test flexibility in all directions
Tendon Joint Inspection:
- Look for wear and cuts, especially around bolt holes
- Test flexibility gently
- Pay attention to bolt hole areas
Replacement Guidelines:
- Tendon joints: Replace annually or after 120 hours of use
- Power/Boge joints: Replace when showing wear or damage
- When replacing U-pins in Power/Boge joints, applying heat can help break down glue for easier removal
Remember: A quick pre-session check of your baseplate can prevent equipment failure and keep you safe on the water.

Windsurfing Baseplate FAQs
When it comes to windsurfing, the baseplate is often underestimated as just a simple connection point between the board and the rig.
The baseplate is a sophisticated component of your windsurfing setup, serving as the critical link in your entire system. It plays a vital role in power transmission, shock absorption, and responsiveness to sailing conditions.
Choosing the right baseplate can significantly impact your windsurfing performance, safety, and overall experience.
This FAQ aims to provide you with the necessary information to help you choose the perfect baseplate for your riding style and conditions.
There are three main types:
- Power/Boge Joint: Great shock absorbers with more sideways movement
- Tendon Joint: Stiffer with less lateral movement
- Cardan Joint: Easily pivoting, ideal for inflatable WindSups
Power Joint is an imitation of the original Boge Joint. The Boge Joint is slightly more expensive and has an unconfirmed reputation for longer lifespan, but both function similarly.
It depends on your use:
- For shock absorption: Power/Boge Joint
- For direct feel and less movement: Tendon Joint
- For inflatable WindSups: Cardan Joint
Unifiber RDM masts stay at a constant 33 mm. internal width up to 600 mm. into the base section. Beyond 600 mm. the internal width tapers to 32 mm.

Baseplate Fundamentals
What's the difference between a baseplate and a deck plate?
There is no difference - they are two names for the same part. We use the term baseplate for simplicity.
What are the main pin systems available for baseplates?
There are two main systems:
- U-Pin: The most commonly adopted standard, featuring ergonomic push-button or trigger mechanisms
- US-Push Pin (US-Cup): Widely used in America, requiring simultaneous pressing of two pins to disconnect
What are the advantages and disadvantages of each pin system?
- U-Pin advantages: More ergonomic operation, easier to connect/disconnect
- US-Push Pin advantages: Very robust system
- US-Push Pin disadvantages: Less ergonomic, more play between baseplate and extension
