Baseplate Tendon Joint Cardan HD (U-Pin) V2
Heavy-Duty Convenience for Demanding Windsurfers
The Cardan HD Baseplate is built for windsurfers who push their gear hard—and still want a quick, no-hassle rigging experience. Its true cardan joint design makes attaching your rig simple and intuitive from any position, whether you’re on the beach or chest-deep in the water.
Perfect for wind foilers and high-performance freeriders, this second-generation baseplate is engineered for maximum durability and effortless function in even the harshest conditions.
The rugged TPU tendon is anchored by oversized custom bolts for easy replacement and secure performance under load. The full stainless-steel connection path from the T-nut to the extension ensures a solid, direct feel with zero compromises—perfect for riders who need absolute confidence in their setup.
Thanks to the push-button quick release system, detaching your rig for transport is fast and frustration-free. The EVA grip disc adds stability on deck, and the Spectra safety rope rated to 650 kg delivers backup security if things go sideways.
Why riders love it:
- Mechanical cardan joint makes rigging effortless—especially for foilers
- Reinforced tendon design handles high stress with ease
- Stainless steel U-pin and bolt system for bombproof reliability
- Tool-free quick-release system for easy packing and travel
- POK engineering plastic is strong, ergonomic, and built to last
- Spectra safety rope for added peace of mind
Whether you’re chasing speed, lift, or big turns, the Cardan HD Baseplate keeps your connection to the board rock solid—with convenience and confidence to match.
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

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
