Product Description

The Adventure Paddleboarding Sixty-Forty is a true hybrid Stand Up Paddleboard (SUP) that will transfer from the surf to flat water without missing a beat. This dual-purpose SUP is very versatile and a great option for the cross-training enthusiast who likes to do it all on the water.

OUTLINE: Full bodied, with plenty of curve along the rail to maximize turning performance, and allow the board to pivot smoothly off the tail. The generous width though the mid zone maintains exceptional stability during flat water excursions.

ROCKER: The rocker is designed primarily for the surf with a little extra lift in the nose and tail to fit with curve of the wave and also make turning easy. A flat section through the middle maintains flow and forward acceleration in flat water.

CONTOURS: The subtle displacement hull reduces slapping and helps cut though the water, single concave through the middle maintains down-the-line speed, and double concave vee out the tail enhances rail-to-rail sensitivity.

FOIL: While most of the volume resides through the mid section, the nose and tail have been foiled to enhance turning sensitivity. Soft, high volume rails provide exceptional stability and are very forgiving when pivoting off the tail.

FIN: Versatile 2 + 1 set up lets you customize the feel in different conditions, and allows for more controlled maneuvers in the surf.

CONSTRUCTION: X-1 uses epoxy resin, woven fiberglass and a lightweight EPS core. This versatile construction is lightweight, durable and has long-lasting flex properties.

FEATURES: Comfortable cavity handle for easy transportation, soft deck traction with tail kick, additional nose plugs for creating a forward storage zone, plus a bonus nose plug for mounting a GoPro.

APPROX BOARD WEIGHTS: 8’8 – 10.4kg/22.9lbs, 9’4 – 11.8kg/26lbs, 10’0 – 12.9kgs/28.4lbs.

Technical Info


X1 Epoxy

X-1 Epoxy is a simple and effective construction using epoxy resin, woven fiberglass and a lightweight EPS core. The EPS core is cut directly from the shapers files, and once custom shaped, is glassed in the traditional hand layup method with multiple layers of woven fiberglass imported form the USA.

This versatile construction is lightweight, affordable, and is particularly suited to manufacturing SUP's. X-1 Epoxy boards are most popular for their subtle flex and memory recall properties, which translates into a board that feels light and responsive, and offers reliable performance regardless of the conditions.

  1. 5 out of 5 First time rider

    Just bought a 10ft board from Serious Surf Stuff in Inverloch. My wife and I bit the bullet and instead of hiring jumped straight in and bought this. After consultation wife the staff there we got measured and were out the door with the 60/40 in Blue. Took it straight to the beach and was amazed at how easy it was to use. Neither of us fell off on the first go. With the ease came confidence. Next day we took our friends out to use it. They to loved it so much there buying one also. It was great with one dad and two kids on it as well. I love the shape as it is similar to my surfboard shape. I’d like to get the two extra fins as well. I am so glad my first board is so cool. I’m really addicted now. This might be my first and last board. I’ll be stoked when I catch a wave on this. We are planning to make use of the front position to carry bags and do small trips on it to explore as well.
