A great performance board designed for the big guy or average fitness surfer so you still feel the power.

EPOXY Options – See ‘Description’ tab below.


The BIG J is a performance board designed for the big guy or average fitness surfer.

The design is based on the J-FORCE model, but with increased volume.

The BIG J’s added volume is incorporated through mid-rails and evenly distributed foam. It has a single to double concave, where Gav specifically moved the double concave under the front foot for more ease in turning.

    I am generally not a big talker, however I can’t help but talk up my Big J 6’ 5” and Classic 9’ 4” surfboards. So much fun. If only there was more time in the week to ride them.
    Gav’s advice with respect to board size and shape has definitely improved my surfing.

    Just had my first surf on my BIG J and loved it. Awesome paddle power, better than my 40L boards. It’s plenty fast enough and a lot more forgiving on drops, and floats sections nice too. I had to change my surfing and surf more performance rather than surfing high volume flat rocker style (stopped being lazy). Shot Nikki and Gav. Look forward to meeting you in person. Thank you for hooking me up another board. You guys are awesome.

    I purchased a custom BIG J 6′ 6″ x 19 5/8″ x 2 1/2″ 33.4L from 1-DA four or five months ago. I went from a 6′ 7″ more of a rounded pin to a bit squarer. I wanted something that was a little looser and would hold into the pocket. And something with a heavier glass job to last, as there’s a lot of rocks where I mostly surf. The waves I mostly surf are around head high but have had a day up to 5ft or so. Enjoying the board. Holds in well. I’ve had a couple I’ve taken off on that I didn’t think I’d make the section on but did and have managed to pull into a few pockets for a quick cover up. I’m finding it easier to bring it all the way round when cutting back or coming off the top, able to whip it back around out of the pocket where before I was coming out of the turn with more a faded bottom turn or off the bottom of the wash. Mainly been surfing lefts but had a few fast rights and the board kept up and have managed to vert on a couple (but ate it on one!). I can also get a lot of speed when driving off the bottom of a wave. All and all, very happy and would not hesitate to recommend a board from 1-DA!

    I absolutely love my new board (BIG J). It’s amazing!!!

  5. Kevin O Keeffe

    Finally got my BIG J wet. Lucky me … the ship was docked in Palau and it was 7-8 foot at West Passage on my day off … life is great. Thanks for an amazing board. It worked great on my first day out, even though I never surfed a reef break before.

    Hi Gav. I’m loving my BIG J. You nailed it. It is exactly what I was after. Ideal in mid to overhead ++ waves. And THE MULTI is ideal for small to medium waves. Thanks mate.
