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.

  1. Chris G

    Absolutely love my Big J – it gives me the turning ability and extra rocker I need while not sacrificing size and volume. Literally the perfect board for me. Gav is such a legend and luckily he’s my neighbour and even goes to the trouble of watching me surf so he can shape me a better board. Can’t say enough about how amazing 1-DA boards are.

  2. Stormn

    Loving my BIG J. One of the best boards I’ve ever ridden. Gav was fantastic on the phone, genuinely interested and keen to get something to work for me. I’m 46 and not small at 6’6 and 110kg “on a good day”. Still not ready to give up the short board and if anything riding this has given me the motivation to shed some more kilos and no doubt surf even better on this board. Thank you guys for a top product and for making my surfing enjoyable again.

  3. Brent

    I couldn’t speak more highly of the boards I’ve gotten from 1-DA; not to mention the excellent experience of dealing with Nikki and of course Gav himself.

    My first order was a BIG J, as I was looking for a slightly more performance shape, but one that was still forgiving for a tall weekend warrior. It’s a joy, being both super responsive yet easy to get up and going on. After our chat, Gav tweaked the design, widened up the nose, so it better suited me.

    Next cab off the rank was a CHEATER. This little thing is so fast and fun when there’s less push in the surf. I was trying to order a longer version of the board, but Gav guided me towards something shorter, instead pumping up the volume. I’m very glad he did, because the result is a fast, nimble, and ‘squirty’ board that makes smaller days a blast.

    Just had my surf trip, got skunked by the weather a bit but still scored some pretty nice waves.
    I took my board out for a test drive in a fun left hander, around 4ft and a pretty fun but mellow wave. Just wanted to feel how it felt under foot. Good news – it went unreal! The paddle power is exceptional, the rails spot on – didn’t catch or grab a rail at all on any turns on my backhand. Really responsive and the tail shape allowed me to get nice and tight in the pocket even on the smaller waves. This was great as I was pretty knackered after surfing all day on my short board and wanted a cruisier surf and it was the perfect board for that.
    I actually surfed it as a quad which probably wasn’t hollow enough for that set up but the glide I got through high line top turns was great. I was able to crank my turns out a bit wider and rebound really nicely off the white water and into the next turn which I often lose momentum on with my short board. Feedback from my mates was that it slowed my surfing down and suited my surfing style really well, and looked really good under foot. So I am stoked Gav. Didn’t get to surf it in hollow pumping waves yet but have every confidence it will be unreal.

    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.

  6. Rob McCarten

    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.

  7. Mitch

    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!!!

  9. 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.

  10. Andy

    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.
