Made in-house

Joe lays up his own fibreglass fin panels, then cuts, foils and signs each fin. This is how a fin comes together, as he has shown it in his Instagram stories.

Lay up the panel
Glass cloth goes down on the bench, layer after layer. Joe held one cured panel edge-on: "That's what 38 layers looks like."
Tint the resin
Pigment is stirred into the resin, and the tinted resin is poured onto the panel.
Mark out and cut
A timber template is set on the cured panel and checked with calipers, then the fin is cut out.
Foil by hand
Each fin is ground and foiled by hand at the bench.
Sign and fit
The fin carries the Cd logo. In Joe's words: "Fin ready to be signed and glassed in".

Wooden fins under the tail of a Cross Design board resting on a concrete floor — Hand-shaped wooden fins

Fins shaped by hand in the workshop, made to suit the board they go on. One recent 6.6 Asymmetric Mid-length went out "featuring hand-shaped, glassed in wooden fins", from Joe's Instagram.

Glass-on fins

Fins can be glassed straight into the board during the build, so the fin and the board become one piece. Shaping, glassing and repairs all happen in Joe's own workshop, so it is done in one place.

Open water paddling fins

Joe also makes fins for open water paddling. He introduced one new shape, to be made in burgundy red, as "the newest addition to my open water paddling fin collection".

When he posted "2 sets of custom navy tint fins coming up.", @allpaddling shared it on with the words here.

"The R&D never stops. Thanks to @crossdesign.online. The best in the business"

Fin questions

Can you put keel fins on a mid-length?

Yes. Cross Design mid lengths have gone out with keel-style fins: the Duo | Mid, an earlier twin, was often fitted with wooden keel-style fins, and an Asym | Mid has been built with timber keel fins. The set-up is chosen with you around the board and how you surf.

Can fins be glassed on?

Yes. Fins can be glassed straight into the board during the build, so the fin and the board become one piece. Glass-on fins are made for restorations too.

Do you repair fin boxes?

Yes. Ripped-out or cracked fin boxes are repaired and colour matched to the board, stripped grub screw holes can be re-threaded instead of replacing the box, and a 5-fin set-up can be converted to a single fin box. Send a photo for a free quote.

How are your fins made?

Joe lays up his own fibreglass fin panels in the Currumbin Waters workshop, tints the resin, then cuts, foils and signs each fin by hand. He also makes hand-shaped wooden fins, glass-on fins and open water paddling fins.

Can I choose the fin colour?

Yes. Fin tints are matched to Pantone: Joe picks the colour against a Pantone book, then mixes the pigment into the resin. Tints made so far include navy, blue, burgundy red, green, yellow and black.

What fin systems do you fit?

The Blade is fitted with official Futures fin boxes, and twin, thruster, quad, 5-fin and asymmetric set-ups are all built. The set-up is chosen with you around the board and how you surf.

Do you have fins in stock?

Yes. Cd-branded fins and Sex Wax are in stock. Ask what is on the rack before you come in.

Where do I collect my fins?

Collect them from the factory at 2/14 Nuban St, Currumbin Waters, on the southern Gold Coast, or have them glassed straight into your board. The shop is open Monday to Friday 9am to 4:30pm and Saturday 9am to 12pm, and you can contact Joe 24/7, 7 days a week.
