DUO, Twin pin, twin fin surfboard
The Duo is a carefully crafted evolution of the classic fish. Its refined tail outline gives you an easier transition onto the rail and more control when the waves have more power.
It really comes alive in small surf, thanks to extra thickness through the chest and a flatter entry rocker. An everyday board for beach breaks, reefs and points.

HOW JOE TAILORS IT

What riders say
Great place, Joe is so friendly and helpful, and his custom boards are just totally beautiful! Highly recommend.
Had my surfboard shaped here by Joe. Connection at first sight. Great human besides being an excellent shaper. He understood straight away what I needed.
Now every time I take the board out of the bag I smile. Been getting heaps of compliments from other surfers too whenever they see it.
Highly recommend.
Joe from Cross Design surfboards has done a fantastic job on many boards for me. Old restoration work through to new boards, all super professional and I'm a very happy customer. I would highly recommend!

What size Duo should I order?
Joe sizes every Duo around your height, weight, ability and the waves you surf. The Duo can be shaped from 5'6" to 8'0". Joe settles the exact length, width, thickness and volume with you at the free consultation. How to size a custom surfboard.
What waves does the Duo suit?
All conditions from about 2ft to 6ft (face). It excels in small surf thanks to the extra thickness through the chest and flatter entry rocker, and the refined tail gives you control when the waves get more powerful.
How long does a custom Duo take, and what comes with it?
Boards are ready 4 to 6 weeks from purchase. Every board comes with grub screws and a leash rope.
Can I have it in EPS or Carbon Fiber?
Yes. Boards are built in PU or EPS, and Carbon Fiber is available on the whole range. Joe will talk through which suits how you surf. Read EPS or PU.
Do I need to come into the factory?
No. Call or text Joe on 0422 435 689, or drop into the factory at 2/14 Nuban St, Currumbin Waters, Monday to Friday 9am to 4:30pm and Saturday 9am to 12pm. You can contact Joe 24/7, 7 days a week.
Is a twin fin faster than a thruster?
In small, soft waves a twin usually feels faster, because two fins make less drag than three, so it picks up speed quickly and feels loose. A thruster's centre fin adds hold and control when the waves get steep and powerful. The Duo's refined pin tail is there to hold on the rail when the waves have more power.
Are twin fins harder to surf?
Not in the waves they are made for. A twin is fast and loose in small to medium surf; the trade-off is less hold at full rail in steep, powerful waves, where a thruster or a twin with a tail outline designed for hold is easier to trust. The Duo has that kind of tail, and suits beginner to advanced surfers.
