SUP Click Fin Side Fins

Hi Mike,

Thank you for sharing your experience, and we're really sorry to hear about the frustration with the fins.

In general, the side fins are most impactful for surfing or making sharper turns—so for regular paddling on calm water, using just the center fin still offers good stability and tracking.

That said, we understand losing fins can be inconvenient. We recommend making sure the screws are fully tightened when installing the side fins, as a loose connection can sometimes cause them to fall out during use, even with light contact.

We appreciate your feedback and are always working to improve our designs—thank you again for supporting Thurso Surf!

Kind regards,
Thurso Surf Team

Dear Kerri,

Thank you for reaching out, and I’m very sorry to hear about your recent experience with the fin system. We truly understand how disappointing it can be to encounter any issues while preparing for a great day on the water.

Our Click Fin system is designed for quick and secure installation, and in most cases—especially when the locking mechanism is fully engaged—it provides a reliable hold. That said, we do appreciate that every setup environment can vary slightly, and it’s possible for unexpected issues to arise.

To ensure the best fit, we recommend carefully aligning the fin and pressing it firmly until it clicks into place, followed by tightening the screw completely until it passes through and locks. This step is important for ensuring a secure connection, especially when using the board in dynamic water conditions. The system is also compatible with a wide range of FCS-style fins, offering flexibility for different preferences.

If you’d like a replacement to feel confident moving forward, we’d be happy to assist. Please let us know, and we can arrange a solution right away.

Thank you again for your feedback, and we’re here to help however we can.

Warm regards,
Thurso Surf Support Team
