The bad news. After 5 years Boogie no longer makes them. He left NZ a year ago to live in Switzerland for 2 years.
The good news. He is still playing around with designs with Martin van Meurs (top Dutch speedsailor) improving on his X2 fins and he has struck a deal with Prolimit and they will make and market these new designs. I think they are pretty close to market...
There are local retailors who are able to supply Prolimit products.
