Preferred For

The Blackfin CX Ultra is a well-performing paddleboard for beginners, intermediate and advanced paddleboards. However, it is especially preferred by intermediate and advanced riders as it ensures the speed and stability experienced paddleboarders look for. The Ultra paddleboards are suitable for all locations and are counted under paddleboards with an easy traveling experience.


The Blackfin CX Ultra is known for its good performance in terms of stability and speed. Nevertheless, the speed of the CX ultra is a significantly better performing feature than its stability and counts under one of the best lightweight paddleboards.

Suitable Locations

The new and stable ULTRA range paddleboards are your perfect companion for exploring every kind of water sport. Whether cruising a canal, exploring a river in the Rockies, or surfing along the coast, the Blackfin CX Ultra has it covered.

Stiffness test

The Blackfin CX Ultra is one of the stiffest boards we have seen.

Take the stiffness test by setting the CX Ultra on two sawhorses about eight ft. apart. When you successfully place the paddleboard on the sawhorses between the given distance, put 120 pounds in the middle of the board. When the 120 pounds is put on the board, it deflects only an inch from its original state.

Most of the stiff boards deflect up to about 3 inches. This test proves that the CX Ultra is a stiff paddleboard even after being lightweight.

How it performs on the water

The Blackfin CX Ultra performs amazingly on water. We simply loved its performance in the water. The board feels relatively rigid and stiff in the water. It is so stiff that you won’t feel it flexing and bending around in the water, even with heavier paddlers. It feels substantial under your weight, and you won’t experience any flex under the feet.

It feels very solid, and the narrow tail design gives less drag, is a bit faster when taking a turn, and you can feel it plowing through the water quite efficiently.

It is a strong, rigid board, unlike most all-around paddleboards that feel squishy and bendy on usage.

Weight Capacity

The Blackfin CX can be used for riding solo or as a pair with a capacity of up to 320 lbs. It can easily accommodate and hold plus-size paddleboarders looking for an excellent paddleboarding experience. Its sturdy and rigid build makes it suitable for handling a significant amount of weight even after being one of the best light-weight SUPs.

Even while paddling, it feels rigid and stable under your weight. It cuts through water smoothly, even with heavier paddlers.



The Blackfin CX Ultra is perfect for:

  • Paddlers who prefer a compact, inflatable SUP that can be their adventure partner for all kinds of paddling locations.
  • Paddlers who need a strictly performance-oriented paddleboard that doesn’t compromise between board weight and rigidity
  • Paddlers who are looking for a high-quality kit and accessories
  • Paddlers who are looking for an all-rounder performance paddleboard with incredible speed and tracking capabilities without losing out on maneuverability.
  • Paddlers who are looking for paddling in mild ocean waves or float paddleboarding in flat waters.
