I'd would imagine that your best bet is to check with some of the Swedish racers or retailers. Try and post a request in the Facebook group Supsverige.se or send them a message. I live in one of the neighbouring countries so I don't have any specifics. Hope this helps.
@Hawaiiheke I migth be able to help yo get in to contact with a few of the swedish crew, are you on facebook? Neith is australian ,living in sweden, try sending her a message : www.facebook.com/neith.astradsson
Swedish people all speak excellent English, I would google translate the swedish pages and contact the european board suppliers. I think there is also an English sup magazine that would be worth contacting. Sweden should have some amazing SUP and you could potentially sup for days at a time in summer. Enjoy!!!! They usually party all summer though. My sister studied at Uppsula University. Heard the parties are great and make sure the bod is tight as they like to hit the spa alfresco style.
