Sirius 40 DS Buyer's Guide
The Sirius 40 DS is a semi-custom deck-saloon cruiser launched in 2015 and built by Sirius Yachts in Germany, offered on the used market in a wide range of interior and keel configurations. Because every boat was custom built to the owner's wishes, brokerage examples differ in layout, equipment, and draft arrangement, so a shopper needs to read each listing against the underlying design rather than expect a standard specification. The boat's appeal rests on a raised saloon with all-round views, genuine offshore structure, and the rare ability to choose fixed, swing, or twin keels.
Layouts on the Used Market
Most used Sirius 40 DS yachts show the raised-saloon plan with the dinette to port and a V-berth forward, but the semi-custom nature means the lower level varies widely. Some boats have a large mid-ship double berth tucked under the saloon on the port side, prized for minimal motion; others substitute a workshop and deep storage reached through a hinged dinette bench or directly from an aft cabin. More than eight distinct interior requests have been recorded, from 2+2 to 6+2 berths, including a lower-lounge or office version, so a buyer should confirm which private sleeping areas and systems access a given hull actually has. The diagonally mounted aft cabin and optional separate entrance via sliding hatch appear on certain plans, while the four-cabin version adds a forecabin suite with en-suite head and a longer galley.
Equipment and Common Upgrades
Given the custom build, equipment clusters matter more than a generic inventory. For power and energy, boats may carry the standard Volvo Penta D2-55 saildrive plus a gen-set or laundry in the workshop area, and the house bank is three consumption batteries totalling 300 Ah with a 50 A shore charger—upgrades to larger banks or solar are owner-driven. For sail handling, the Solent rig with self-tacking jib and traditional genoa is standard, while a carbon-performance rig is a notable factory upgrade to look for. Navigation and comfort centre on the interior helm station, recessed deck-saloon safety glass, and opening galley windows; some owners add double glazing. The fold-down transom door, Flexiteek cockpit, and 4500-litre cockpit seat storage are common, but buyers should verify which stern arrangement—drop-down wide door, small transom door, or closed swim step—a hull carries.
What to Inspect
The one system that demands survey attention is the swing keel mechanism, described as very reliable and safe yet complex technology, with its ballast-moving centreboard box integral to the hull. On twin-keel boats, check the structure that supports the yacht upright on tidal flats, since that set-up is built to bear the boat and its contents twice daily. More broadly, confirm the hull-deck connection and bulkheads remain fully laminated, the fourteen 20 mm keel bolts show no staining, and the underwater epoxy and antifouling are intact. The deep underfloor compartments and hidden workshop should be opened to inspect engine access, electrical runs, and water tanks.
Availability and Buyer's Takeaway
When evaluating a specific Sirius 40 DS, a short checklist helps:
- Confirm keel type and whether swing-keel hydraulics or twin-keel grounding wear are appropriate to your cruising
- Verify the actual berth count and workshop access against the stated layout
- Inspect keel bolts, laminated structure, and underwater finish closely
- Match equipment clusters—rig, energy, navigation—to your intended use rather than assuming a base spec
