UNIFIBER BASEPLATE TENDON JOINT CARDAN ESSENTIALS (U-PIN)

The Essentials Cardan baseplate combines Unifiber’s tendon joint core with a mechanically hinging top.

While suitable for all windsurfers, wind foilers can particularly appreciate this baseplate. With its cardan hinge, attaching the sail — whether on the beach or in the water — is simple, with no need to flip the board or manually bend the tendon.

Built around a high-quality TPU tendon, the core is anchored by two large-diameter custom bolts, ensuring easy tendon replacement without the risk of bolt damage.

The U-Pin section is crafted from solid stainless steel for long-lasting durability.

Made from tough POK engineering plastic, the baseplate is ergonomic and easy to unscrew—even after intense sessions. The POK disk includes an EVA layer and a guiding knob, offering excellent grip on the board.

For added safety, a Spectra safety rope connects both the top and bottom parts of the baseplate, capable of withstanding up to 650 kg of break load.
