Comparable Paddleboards

The Isle Cruiser paddleboard is another one of our top rigid paddleboards. Thanks to padding, the board has a sturdy build and the sole comfort of a classic inflatable. 

The Isle cruiser has a slightly lower carrying capacity at 235lbs. It may not be the best choice for everyone as it does require a bit of expertise and practice to get used to. 

Contrary to the Blackfin SX, which is designed for newbies and has a carrying capacity of 250lbs and more attachment and storage areas.

Our Verdict For The BLACKFIN Model SX Hard Board

The Blackfin inflatable SUP lineup is loved by many. But their hardboards are rather underappreciated. The SX solid board’s build, design, performance, and durability remain elite. The stability and easy maneuverability make it perfect for beginners as well experts.
The board comes with a complete set to get on the water straight away. If you purchase some of the addons, such as the kayak kit, cooler, and mounts, you’ll be set up for many different adventures that will allow you to be outdoors all day.
With proper care and storage, this paddleboard can last a long time. With the included 3-year warranty, you can buy this solid SUP with confidence.
