Today's inflatable stand up paddle (SUP) boards are lighter, stiffer, and better performing than ever before. While their overall performance isn't quite on par with rigid fiberglass boards, their ease of transport compared to traditional boards provides easier entry into the sport for many new paddlers. Many inflatable models in our lineup include everything you need to get on the water in one convenient package. Each board has a different shape, different level of stiffness and stability, and includes different paddling accessories and transport features, all of which impact the paddling performance or convenience of use. Our testers spent several months unpacking, inflating, paddling, and transporting these boards to identify which model would be the best for you! Below, we break down our testing process and describe each rating metric that we considered.

Stability


The ability to remain upright while floating on an undulating body of water is a key element to successful paddle boarding. While the rider is an active participant and must engage their muscles to promote stability, key features of the board have a strong influence on the paddler's success. We tested each model's inherent stability by using and accessing the board's performance in a variety of settings. We had beginners who had never SUP'ed before or been out less than three times try each model. Intermediate and experienced paddlers rode the boards on choppy water into the wind. We put multiple people on the same board, sometimes with an additional canine companion, and we even attempted yoga, including some partner acro-yoga, on the different models.

Glide Performance


To assess each board's glide performance, we established a straight course between two fixed points and had the same rider count paddle strokes when the water was flat with wind forecast ≤ five mph. We then time-tested each model on a measured course with the wind forecast ≤ five mph. During the time trial, we tracked each board's ability to stay true to the course using Strava, a GPS tracking application, to visualize the boards' path.

Maneuverability


This metric is all about ease of turning and avoiding obstacles. Paddler technique plays a small role, but the design of the board is the primary factor to consider here. To evaluate the dexterity of each board, we designed a slalom course and had the same rider run a time test using each board. The course included three 180 degree turns using only forward strokes. We also evaluated each board's turning radius in a 360-degree turn with back paddling and again with forward paddling. We tracked the turn shapes with Strava. The final score for this category was based on the paddler's opinion, the observable results, and the GPS track of each board from the Strava iPhone app.

Ease of Transport


The biggest advantage of inflatable paddle boards over their hard-bodied siblings is the ability to pack them up into small, easy to move packages. To assess the transportability of each model, we packed, unpacked, carried, rolled, and moved the boards over and over again for months. We carried each board in its accompanying backpack over flat terrain, on hiking trails, and cross country to remote alpine lakes. We carried them while inflated from the car to the water and when portaging in rivers. We scored each board based on the comfort and convenience of ferrying them around.

Ease of Inflation


The most challenging part of using an inflatable SUP is filling the board with enough air so that the resulting pressure is sufficient to create a rigid platform. To determine which models were the easiest and the most challenging to inflate, we timed inflation from start to finish using the provided hand pumps and with a hand pump, electric-pump combination when provided. We also factored in the quality of the pumps.
