THE O'SHEA 12'6" GTR HPx...


Our advanced HPx construction is a market leader in iSUP construction. HPx boards are 20% lighter than any FUSION or MSL constructions, with no detriment to the durability or cosmetics of the board. HPx results in numerous performance benefits... which are of particular importance for touring and race boards - including, effortless gliding, great stability and easy transportation.


The combination of a lower profile, 12'6" length and super lightweight but rigid HPx construction results in one speedy SUP! The board perfoms in a wide range of water conditions and is a go to board for thos looking for a combination of mild ocean or river going exploration and race potential. On glassy water, the speed of the GTS really comes into its own.


THE GTR our race model - go far - go fast! It is also supplied with 1 years manufacturers warranty extendable to 5 years by registering online.


HI-TECH HEAT WELDED SEAMSAll 2024 HPx boards now incorporate state-of-the-art heat-welded seam technology. This provides a stronger seam and an enhanced cosmetic finish.


Despite the light weight of the HPx construction, the durability of the board is maintained, along with its resistance to UV. The hi gloss finish of the GTR HPx not only looks pretty cool, but also serves an important safety purpose, with a highly visible board on the water. It looks great on the beach too! The cosmetic finish on the board is glossy and immaculate.


All our HPx boards are shipped with a 3 piece, adjustable, high quality HYBRID CARBON paddle. These have a fully adjustable telescopic handle and the hybrid construction provides a lighter, stiffer and therefore a more efficient paddling experience than aluminium. This will enhance your touring adventures.

SUP MAG UK Review " ... a sure-fire winner..."

"The O’Shea GTR HPx 12’6 inflatable SUP offers high performance for SUP racing and touring. Its top-tier construction ensures lightweight rigidity and efficiency, appealing to riders wanting a multipurpose, competitively priced paddleboard.

As with all O’Shea inflatables, the manufacturing and quality are bang on. HPx construction ensures a light and rigid lay up. This provides the best combination of stiffness and weight. The board’s light weight allows it to drive through the water hard (when required). Whilst its rigidity provides efficiency. In combination, this equates to less effort required from the paddler but with better returns on performance.

Combination of riders
During testing, we had a combination of riders use the board, and all commented on the GTR’s glide. Keep in mind this is an iSUP, which is top drawer. Stick a few strokes in, and the 12’6 keeps going. For those considering SUP racing, this would be a massive plus point.

But the GTR isn’t limited to SUP racing alone. With paddlers wanting more bang for their buck, the O’Shea steps up to deliver on the touring front. 

Multiple SUP disciplines
The GTR, at 28” wide, is just enough to accommodate a few essentials being lashed to the deck. You won’t necessarily be able to carry the kitchen sink with you on your travels, but a few bits can be taken. And then it’s a rapid rise to your chosen destination. So, fast touring if you like. Being able to cope with multiple SUP disciplines should certainly get your attention, and take note of the O’Shea GTR 12’6.

O’Shea’s comprehensive range of inflatable paddle boards means there’s something for everyone. The GTR 12’6 HPx fits the bill for riders who want to paddle fast and be competitive on a race course. Yet, at the same time, adventure paddling and touring are applicable with the same board. With that added value, the GTR is a sure-fire winner for riders wanting a performance-orientated iSUP that does multiple jobs. Tip-top construction and decent looks only add to the board’s appeal. Thanks also to Adrian Taylor and Tom Pringuer, who helped with this test.
