The Expedition 138 11′6″ Inflatable Paddle Board blends touring speed with all-around versatility — designed for fitness paddlers, distance explorers, and gear-carrying adventurers who want more out of every session. With its slim 11′6″ × 30″ profile, it offers outstanding glide efficiency and tracking, while remaining stable enough for intermediate users and confident beginners alike. Engineered for lightweight strength, the board features a woven drop-stitch core and reinforced carbon rails, striking a perfect balance between rigidity and portability. Choose between 6″ thickness for added volume and load capacity, or 4.7″ thickness for a lower, faster feel closer to the water.

Welded Rails eliminate glued seams — increasing durability and reducing the risk of delamination. A cup holder mount and action camera base are also integrated for convenience during fitness paddling, long rides, or scenic excursions. Ideal for paddlers with smaller to medium builds, the Expedition 138 has been newly upgraded with an electric pump and a free deck cooler in 2026, further enhancing usability and user experience.

Woven Drop Stitch

Woven threads connect the layers for higher inflation pressure, resulting in a stiffer, more responsive board that performs like a hardboard yet remains inflatable.

Fusion Lamination

Fusion lamination uses heat and pressure to fuse two layers of high-quality PVC, making our inflatable paddle boards lighter, more durable, and structurally stronger. This process reduces weight while increasing stiffness for a smoother surface.

New Welded Rails

Welded Rails fuse layers at the molecular level, creating stronger, more durable seams than glued ones. This reduces leaks and delamination, enhancing the SUP board's longevity and consistent performance.

FAQs

A touring SUP is best for flatwater distance paddling, efficient glide, and covering more ground with less effort. The Expedition 138 is shaped for tracking and forward speed, so it suits longer lake, river, and calm coastal paddles better than a shorter all-around board.

It can be, if you already know you want a board mainly for flatwater touring and steady cruising. For a first board used across different conditions, the Waterwalker 126 is more forgiving, but the Expedition 138 is a good beginner touring choice for paddlers who value glide over playful all-around handling.

The Expedition 138 is longer and more efficiency-focused, so it tracks straighter and glides better than an all-around SUP. An all-around board is easier for casual mixed use, small surf, and tighter turning, while the Expedition makes more sense when distance and flatwater speed are the priority.
