From what I read, Merlock is correct, it is basically the Gowind 200 design but with a different propulsion system that allows it to reach those high speeds, so if you see a picture of the Gowind 200, you are pretty much looking at the Fastwind. It is competing against the LCS designs being offered to Saudi Arabia by the US.
I’m not sure about the modularity of that design so my choice would actually be the new MEKO CSL design, combines the best of the MEKO modularity with the lessons learned from the Visby design, not to mention the high-speed >40knots.
