What this builder is
Sirius Yachts says it has built boats by hand 'with love, since 1971', and calls itself the family-owned builder that invented the phrase 'deck-saloon'. SIRIUS-WERFT GmbH, run by Torsten Schmidt, builds at Ascheberger Straße 68 in Plön, Schleswig-Holstein. Every boat is built around one idea: a raised deck saloon with large windows and a 360-degree view, at the same level as the cockpit and the navigation seat, with the galley a step lower so the cook shares the same eye-line, and the space beneath the saloon used a second time for a cabin, a technical room or a workshop. The range covers 31 to 40 feet: the 10.60-metre 35 DS, launched in 2010 as the first of the modern deck-saloon designs, and the 12.90-metre 40 DS flagship that followed five years later, both with Volvo Penta D2-50 saildrives; the 9.30-metre 310 DS, offered in 14 standard layouts, is currently not in production. Each model is available with a choice of fin keels of different draught, twin keels or a fully ballasted lifting keel. Interiors are full-custom in hand-crafted mahogany — no two boats from the yard are identical — and the yard says it draws on nearly half a century of building deck-saloon yachts and the experience of more than 650 owners; once the design is settled the build takes four to six months, and owners are encouraged to visit.
Who sails them
Sirius owners are cruising couples and small families who sail in all weathers and want to see where they are from inside — at anchor, in harbour or under way — and who care about a solid, well-finished boat built to their own wishes, down to the layout of the cabins, a workshop or an office, and the drawers fitted to their own cookware.
Signature models
The Sirius 35 DS is the yard's signature: launched in 2010, it put the space of a 40-footer into a 35-foot hull with its split-level layout, comes in two-, four- and six-berth versions, and after fifteen years the yard says it is as popular as when it first appeared; the 40 DS, on which Torsten Schmidt lived aboard for seven weeks non-stop, is the flagship.
Strengths
The yard points to its raised saloon with an all-round view and an inside steering or navigation position, hand-laid GRP with vacuum-bonded sandwich above the waterline, a choice of keels including a true lifting keel that raises all the ballast, generous headroom of 1.90 to 1.95 metres and more, large storage and workshop space, CE category A, and a custom interior planned with each owner.
Considerations
The model pages give the keels as a list of options rather than a single draught, so the stored draught is the range across them; tankage is printed as 'from … upwards', so the standard tank is stored; no designer is named; the 40 DS gives its length as 'up to 12.90 m' and prints no CE category; and the 310 DS page is still online although the boat is out of production.

History
Sirius Yachts describes itself as boats 'built by craftsmen, with love, since 1971', from the family-owned boat builder that invented the phrase 'deck-saloon'. From its German yard it offers a range of go-anywhere deck-saloon sailboats with hand-crafted, custom-built interiors in mahogany, each available with a single fin keel, a lifting keel or twin keels, and no two yachts from the factory are identical. The yard says it brings nearly half a century of experience building deck-saloon yachts and the experience of more than 650 owners to each new boat: it works through hundreds of design decisions with the buyer — from the rig and sailcloth to the reading lights in the master cabin, and galley drawers made to fit the owner's own cookware — before production begins. The build then takes four to six months; most owners visit the yard several times, receive regular progress pictures by email, and can leave their cutlery, crockery and glassware with the yard so that its storage is made to measure.
