Sirius 40 DS: German Deck-Saloon Mastery for Bluewater Cruising

Introduction & Design Heritage

The Sirius 40 DS emerged from Sirius Werft in 2015 as a premium deck-saloon cruiser. Designer Marc-Oliver von Ahlen crafted a yacht that prioritizes seaworthiness alongside modern livability. The model continues a legacy of hand-built boats from the German yard, with production ongoing today. Owners praise the thoughtful design that balances sailing capability and comfort.
