Roger Cox: Who needs the Roxy Girls when Scotland has its own band of women riding waves?

To a hypnotic synth-pop soundtrack embroidered with faintly tribal-sounding, sub-Enya wailing, a group of tanned, bikini-clad young women frolic underwater like so many slow-motion, soft-focus mermaids.

It could be a TV advert for a Sandals holiday resort, but these are the Roxy Girls, and this is the trailer for their instructional surf film, Roxy - Learn to Surf NOW.

Founded in 1990, Roxy is the female arm of multinational surf apparel company Quiksilver, and these days it accounts for almost a third of the parent company’s annual turnover. The Roxy Girls are the label’s sponsored surfer/models, paid serious money to travel the world, living the beach-bum dream.

The synchronised swimming continues, as does the tribal wailing, and snatches of text are flashed up on the screen: “The Roxy Girls ... invite you ... to share... a beautiful secret... learn to... surf NOW.” Cut to: a slow motion shot of two tanned, blonde girls giggling while tandem surfing at Waikiki. Cut to: a slow-motion shot of a solitary tanned blonde girl giggling while hugging her surfboard and drinking a Slurpee. Gosh darn it, these girls just have so much good, clean, wholesome FUN!

No doubt the Roxy Girls’ film had the desired effect of getting hundreds of young women all over the world into surfing, but it also had one consequence its makers could never have envisaged: the formation of Scotland’s very own female surfing collective, the Joxy Girls.

Caroline Stott, Laura Carse and Sally Harris first started bumping into each other in the mid-Noughties, in the cold, soggy car parks of some of the East Coast’s better-known surf breaks. Delighted to discover they weren’t the only women jumping into the North Sea for kicks on a regular basis, they bonded over hot drinks and chocolate bread and had soon become the focus of an unofficial all-girl surf posse with members up and down the country.

“I think at some point we had all watched the Roxy Girls’ guide to surfing,” says Stott, 32, “and we all thought it was a little bit, er ... I don’t want to say anything too negative, but absolutely nothing like learning to surf in Scotland. I mean, bikinis matching your surfboard, all that sort of stuff – we were just like: ‘Oh my God, that’s hideous!’

“I think we were all just having a laugh together one night and talking about the Roxy Girls, and then one of us came up with the idea of the Joxy Girls – the Scottish equivalent.”

The idea grew legs. Stott and Co set up a Joxy Girls Facebook page, got Joxy Girls stickers for their surf vans and had Joxy Girls T-shirts printed for a group trip to a surf camp in Morocco. They’ve even got local surfboard shaper Jason Burnett making them surfboards with Joxy Girls logos on.

“Our ultimate aim is to make our own DVD,” says Stott, “a spoof of the Roxy Girls’ guide to surfing. We’ve been talking about it for ages.”

On a slightly more serious note, the popularity of the Joxy Girls (120 Facebook followers and counting) suggests that they have filled an important niche in Scottish surfing – a ready-made community that aspiring girl surfers can plug into in what is still a largely male-dominated sport.

“We get a lot of people getting in touch saying ‘I really want to go surfing and I heard you guys are a good crew of women surfers – can I come and surf with you sometime?’ says Stott. “We’ve been back to Morocco a couple of times now, we do a big summer solstice beach party every year and we usually do an annual trip up to Lewis as well, and a trip up to the north coast.”

Add to that already-full calendar the first ever Joxy Girls Weekend, held today and tomorrow at the Innerwick Residential Centre, ouside Dunbar, where, in addition to surfing and beach safety sessions, there will be skateboarding, yoga, massages and makeovers. “It’s all about chatting about surfing and giving each other as many tips as we can,” says Stott. And in contrast to similar male-run events, there will be no competitive element whatsoever.

“There’s a different vibe when you’re in the water with other women,” says Stott. “It’s a lot more relaxed and a lot more supportive. There’s no need to look macho.”
