>>2292220Sorry, I just realized this link wasn't very helpful since it's mostly about that specific boat.
The type is called "SK40" and it's designed around a specific rule for racing.
Wikipedia calls them "Skerry Cruisers" but the Swedish term "Skärgårdskryssare" (the "SK" in "SK40") translates more literally to "Archipelago Cruiser".
Here's the wiki article:
