The J-FORCE is a FAST high performance board designed for all experienced surfers.

The design is based on Gav’s knowledge and experience, specifically when working with Graham ‘Gee Force’ Smith to create magic boards for Jordy.

The J-FORCE hides volume through the mid-rails and evenly distributed foam, creating a board that is easy to manoeuvre and gives you ‘carry’ through radical turns, while maintaining power and speed. It incorporates a single to double concave, where Gav specifically carried the double concave further under the board for more ease in turning.

  1. Chris G

    This is my sixth board from Gav and definitely the best one yet in terms of performance. I’m bigger and heavier than the average surfer but Gav always manages to shape a board that has volume in all the right places and still allows me to fit in turns even with the extra volume. Gav shaped the board in two weeks as well which is amazing. Will never get a board from another shaper. Thanks Gav!

  2. Jamie Ryan

    I got the 6’2 JForce as a step up option for when the waves are firing so I haven’t ridden it as regularly as my Multi but it feels comfortable under my feet and turns on a dime so all good there.

    I initially chose 1-DA after seeing the branding on Gav’s car when I took my daughter to her ballet lesson just down the street from the factory. I did a quick website search and thought that the consultation was a good idea. I’ve ordered a fair few custom boards in the past but never really had that kind of one on one conversation with the shaper before. I really enjoyed just talking about boards with Gav and am stoked with the results. I’ll definitely be ordering my boards from 1-DA from now on.

    I just rode my new JForce this morning……OMG!!! Magic Board!! WOW! Happy as, Thank you!

    I quit the idea of having a 1 board quiver a while ago after being disappointed with so many empty promises from several shapers. There was always something wrong like no paddle power, bogging rails on flatter sections, not enough speed, weird off the bottom, boards that felt dead under the feet, too much rocker, not enough rocker, the list goes on.

    For that reason, when ordering my J-FORCE (my first board from Gav), I wanted to start building a new quiver and was extremely specific. I wanted a board with paddle power without feeling boaty. A standard high performance shape able to handle walled up powerful waves like Deserts and Ulus race tracks, Burleigh … places where my previous boards where under-performing. In other words, I wanted a sort of mini step-up to make the most of 3 – 5 ft powerful waves.

    Gav suggested the J-FORCE and right from the 1st surf the board blew my mind. This 5′ 10” paddles around better than my previous step-up (6′ 3”) for starters! It is super fast off the bat, feels loose without being too crazy, but when put on rail it holds amazingly well with great control and precision, and it always seems to release when needed, making my turns more radical than expected. I took it to the Maldives and it went well on chest high waves and outstanding on bigger powerful surf up to 6ft+. All I have to do is to change fins from a vert template on smaller surf to a raked template for above head high.

    So that is my story, even if it was my most specific order ever, the J-FORCE ended up being that ultimate all-rounder I’ve been looking for in the past that I thought didn’t exist.

    I can finally say if I could take only 1 board on a surf trip anywhere with decent surf, this would definitely be the one.

    Thanks Gav.

    Custom 6’ 2″ x 19 3/8″ x 2 9/16” Round tail, FCSII 5 fin setup, 31L

    I came to Gavin after riding well-known brand standard stock off the shelf boards at surf shops. I was looking for that little bit extra and more defined board that suited me better for overseas in high performance waves but something that could also handle normal days at home. Gav’s knowledge of what I required just from a face to face chat and looking at the boards I was currently riding was great and it didn’t take long for us to agree on what we would go with. 

    From the moment I contacted Gav and Nikki, the process was a breeze. They are so friendly and easy to get along with and I enjoyed the personal easy going approach to choosing what type of board we would go with.

    The board took no time at all to be made and I was shocked to get the call so quickly that my board was ready. The first time I picked up the board it felt amazing, and it felt even better on its first surf and all surfs ever since. 

    I am loving this board and my surfing has gone to new levels with it under my feet. My turns are crisper and the speed I could get in fast barrelling reef breaks in Indo was exactly what I was looking for. 

    Cant wait to get my next one.

  6. Juzza King

    Thanks to Gav and the 1-DA team!
    So impressed with how Gav, from watching footage of my surfing, could really tune into what was needed to take my surfing to the next level. Totally stoked with the result. Best board I have ever owned.

  7. Jude Stevens

    Loving my custom J-FORCE! I’ve had it for a few months now and my surfing is finally progressing to that next level. I expected the board to be fast but I didn’t expect it to also be so stable. I have so much more control than I’ve ever had before while keeping heaps of speed! Gavin was also really easy to communicate with and I could tell he really cared about making a board that was perfect for me. Thanks Gav.

  8. Mark Becker

    The board (J-FORCE) works fantastic. Extremely fast off the bottom. It seems to slingshot to the lip. Something I never experienced. It took a while to get use to actually. Very loose off the top as well, yet still easy to control. Extremely fast as well. Really handles well in overhead surf. Loving it!

  9. Millsy

    Hi Gav. I just wanted to let you know mate that the J-FORCE you made me is the best stick I have ever ridden. It is super fast down the line and is also so solid under my feet through my turns. It has totally improved my short board surfing. Next will have to be a performance mal so I can keep up with my short board surfing – I think I need a Mistress!!!!

    Love your work buddy.

  10. Ben

    Hi Gav. The board (J-FORCE) goes unreal, wouldn’t change a thing. Cheers.

  11. Zane Hicks

    The boards (THE ELITE & J-FORCE) were awesome. I couldn’t be happier.

  12. Chris Wilkes

    I just rode my new 5′ 10” J-FORCE for the first time. As soon as the first ride began, I knew the board had a lot to offer. After 3 waves, I decided it is the best board I have ever owned. I look forward to surfing it again. Thanks heaps Gavin Upson for the time and energy spent to refine the design. Unreal!

  13. Polsy

    Heat win at Kirra Teams Challenge today in perfect pumping Snapper. Stoked on the new J-FORCE craft I picked up just 2 days ago. It’s sick. It’s so fast, feels electrifying. I combo’d the heat score. It’s been a while since that happened. Need to get myself another 1-DA board in my quiver!

  14. Dale Staples

    Howsit Gavin! Amped to have your boards under my feet again! I just picked up my boards and they feel amazing! Thanks so much! I surfed the MULTI and it feels really good!! And the waves were pretty shitty! Going to save the J-FORCE for when it gets better! Update – the J-FORCE is going really good!!

  15. Mike

    I just got my new J-FORCE 1-DA board and love it! It’s been awhile since I’ve had a board feel so good under my feet from the first wave. It looks like there may be magic in this one! Thanks so much Gav.

  16. Jye

    I took that 5’ 11” J-FORCE out at Burleigh today. The thing goes unreal. Two thumbs up!

  17. Damon

    The J-FORCE is really responsive and fast, carves good. It goes mental.

  18. Josh, Palm Alley

    Hey Gav. I took my J-FORCE out today. It worked like a charm! It’s so light under my feet which made it really easy to throw around. I got thrown into a nice little barrel out at Palmy. I did a late drop and closed my eyes thinking I was going to bail but dropped through the roof opened my eyes and was flying down inside the wave. It held really well. My mate was frothing at the build of the board, he loved it. And while I had the board sitting on the grass, a bloke walking past stopped by the board and had a good admire. Couldn’t be more happier mate!

  19. Arthur

    I was in Newcastle for the Australian Surfing University Games these last few days. I reached the quarter finals. I surfed the J-FORCE in every heat and it felt really good. This board is so fast and light so you can make crazy turns with it! I really enjoy surfing this board!
