The Blackfin Ultra CX features new materials for weight reduction while maintaining build quality. It employs a woven drop-stitch core and a new pattern in space yarns to enhance rigidity and reduce weight. The triple-layer composite construction and carbon fiber rail layer add stiffness and impact/abrasion resistance, resulting in a board that is both theoretically and noticeably stiff on the water​​.

Suitability and Activities:

The Blackfin CX Ultra is perfect for intermediate paddlers seeking a performance-oriented upgrade. It is lighter than other Blackfin models, making it suitable for traveling, touring, and recreational paddling. However, beginners may need some time to get used to its stability. The board’s design makes it less ideal for activities requiring more balance, such as fishing or yoga​​​​.

Comparison with Other Models:

Compared to other Blackfin models, the Ultra CX features a shorter width, emphasizing speed and distance travel. It has a narrower tail and fewer D-rings, providing less stability and storage space than the wider XL and X series. The board’s tracking ability, while good, may not match the three-fin setup models like the Blackfin Model V​​.

In summary, the BLACKFIN CX 10’6″ ULTRA™ Inflatable Paddle Board is a high-performance, portable SUP suitable for intermediate to advanced paddlers. Its lightweight design, combined with innovative construction and versatile features, makes it an excellent choice for those prioritizing speed, maneuverability, and ease of transport.
