Overview

Sirius-Werft GmbH is a German shipyard based in Plön, Schleswig-Holstein, specialising in the construction of deck saloon sailing yachts. Founded in 1971 by Peter Schmidt as a family business, the yard has built more than 750 vessels since its establishment and is regarded within its size segment as a pioneer of "true" deck saloon yachts. The company produces roughly 12 to 14 sailing yachts per year with around 80 employees, operating as an individualised small-series manufacturer rather than a mass producer. The yard's identity is closely tied to its deck saloon concept, which combines a raised saloon with large windows and a protected interior helm position, a layout that has proven successful worldwide. Sirius-Werft has sold yachts into 26 countries, and its boats are known for extensive customisation: buyers can choose among different keel variants (including bilge keels and swing keels), rig configurations and interior fit-out versions. The current model range spans three length steps — the Sirius 310 DS (hull length 9.30 m), the Sirius 35 DS (10.60 m) and the Sirius 40 DS (11.99 m) — all designed by naval architect Marc-Oliver von Ahlen together with the yard's in-house design team. Leadership passed within the founding family: Peter Schmidt's son Torsten Schmidt took charge of yacht construction in 1995 and became managing director in 2001. The company remains a private family business headquartered at its yard in Plön, with no public listing. Its positioning is that of a niche, quality-oriented builder of blue-water-capable deck saloon cruisers rather than a volume producer, and its reputation rests on the combination of the deck saloon layout, individualised construction and a model range concentrated in the 31–40 foot segment.

History

Sirius-Werft GmbH was founded in 1971 in Plön, Schleswig-Holstein, by Peter Schmidt as a family-run shipyard. From the outset the yard concentrated on the construction of deck saloon sailing yachts, a type characterised by a raised saloon with large windows and a protected interior helm station. Over the decades the company established itself as a specialist in this niche and is described as a pioneer of "true" deck saloon yachts in its size segment. A generational transition began in 1995, when Peter Schmidt's son Torsten Schmidt took over responsibility for yacht construction. In 2001 Torsten Schmidt became managing director, and the yard has since continued under his leadership as a family business. By the time of the available source material, the yard had delivered more than 750 vessels since its founding and had sold yachts into 26 countries, reflecting a worldwide customer base built on the deck saloon concept and the yard's individualised fit-out approach. Production is organised as an individualised small series: with around 80 employees, Sirius-Werft builds roughly 12 to 14 sailing yachts per year. The model range has been structured in three length steps, and the current palette comprises the Sirius 310 DS (hull length 9.30 m), the Sirius 35 DS (10.60 m) and the Sirius 40 DS (11.99 m). These current models were designed by Marc-Oliver von Ahlen together with the yard's in-house design team, and they offer buyers a choice of modern hull forms, several keel variants (including bilge keels and swing keels), different rig configurations and multiple interior fit-out versions. The company remains headquartered at its yard in Plön and is not publicly listed.
