The Sirius 35 DS is a high-end cruising sailboat designed by the German shipyard Sirius-Werft GmbH. Known for its deck saloon concept offering a 360-degree panoramic view, it combines comfort, safety, and performance for demanding sailors.
Boat History
The Sirius 35 DS was designed by naval architect Marc-Oliver von Ahlen and launched in 2010. Its goal was to offer a compact sailboat with the comfort and interior space of a much larger boat. Since then, this model has established itself as a reference among high-end cruising sailboats. The Sirius-Werft GmbH shipyard, renowned for its quality craftsmanship, has produced a limited number of units to ensure a high level of customization.
Primarily intended for offshore and coastal cruising, the Sirius 35 DS stands out against competitors such as the Hallberg-Rassy 34 or the Najad 355.
Interior Layout

The interior of the Sirius 35 DS is distinguished by a two-level organization, optimizing space and light. The deck saloon offers a panoramic view, which is rare for a sailboat of this size. Various layout configurations are possible, accommodating between two and six people.
The finishes are high-end, featuring noble woods, excellent thermal and sound insulation, and an arrangement that maximizes comfort both at sea and at anchor.
Marine Qualities

The Sirius 35 DS offers several keel options: fixed keel (deep or shallow), twin keel, or lifting keel. This modularity allows it to adapt to different bodies of water. Its moderate displacement and robust construction ensure excellent stability and good seakeeping.
Its well-balanced sail plan and fractional sloop rig facilitate single-handed or short-handed sailing.
Owner Reviews
Owners highlight the exceptional comfort, quality of materials, and intelligent design of the boat. Some note that its weight (7.5 tons empty) can affect its performance in light winds.
However, the stability and safety it offers are widely appreciated. The high price of the Sirius 35 DS is often justified by its durability and resale value.
