Sirius 24 Information, Review, Specs

Sailing Performance & Handling

The Sirius 24 is characterized by its "heavy-weather" small-boat philosophy. With a displacement-to-length ratio that leans toward the heavier side of the cruiser spectrum, it prioritizes stability and sea-kindliness over raw speed. The boat was offered with multiple keel configurations: a deep fin keel for better windward performance and a "Kimmkieler" (bilge keel) version specifically designed for the tidal flats of the Wadden Sea.

Under sail, the boat is known for being remarkably stiff, a result of its high ballast ratio (often exceeding 40%). This allows it to carry full sail longer than many contemporary 24-footers when the breeze freshens. While the hull shape—featuring a relatively full bow and traditional transom—is not designed for planing, it tracks exceptionally well. Owners often report that the boat feels "larger" than its 7.3-meter length would suggest, handling choppy coastal waters without the "hobby-horsing" motion typical of lighter displacement boats. The helm is generally well-balanced, though the bilge-keel versions naturally exhibit more leeway and a wider tacking angle compared to the fin-keel variant.

Interior Comfort & Variations

Despite its modest footprint, the interior of the Sirius 24 reflects the craftsmanship that would later make the shipyard famous. The layout typically features a classic four-berth configuration: a V-berth in the bow and two longitudinal settees in the saloon that double as berths. The use of high-quality wood joinery, usually mahogany or teak, provides a warm, substantial feel that contrasts with the "all-plastic" interiors of mass-produced competitors from the same era.

The boat was produced in several trim levels, most notably the "Luxus" version, which featured enhanced cabinetry and upgraded upholstery. Headroom is limited—approximately 1.45 to 1.55 meters—as is standard for a 24-foot boat of this vintage, meaning most adults will be stooping. However, the galley is functional, typically equipped with a two-burner stove and a small sink. The "Special" variant occasionally seen on the secondary market often included customized locker arrangements, a precursor to the semi-custom approach Sirius-Werft employs today.

Known Issues & Buyer’s Checklist

Prospective buyers of a Sirius 24 should focus on the following technical areas common to GRP yachts of the 1970s:

• Window Seal Integrity: The original aluminum-framed windows are prone to seal failure over decades. Look for water staining on the interior woodwork directly below the ports, as persistent leaks can rot the marine plywood bulkheads.
• Deck Core Moisture: Like many boats of this era, the Sirius 24 utilizes a balsa-cored deck. Check for soft spots around the chainplates and stanchion bases, where hardware may have been re-bedded poorly, allowing water ingress into the core.
• Rudder Bearings: The transom-hung or skeg-mounted rudders (depending on the specific sub-year) can develop play in the bushings. While a relatively simple fix, excessive "thumping" at the helm under load indicates wear.
• Rigging Age: Many of these vessels still carry older standing rigging. Because Sirius yachts were built to high standards, some owners may have neglected replacement schedules. A thorough inspection of the swage fittings and the mast step is essential.
• Auxiliary Power: Many Sirius 24s were fitted with Farymann or Bukh diesel engines. While these are reliable "workhorse" engines, parts are becoming increasingly difficult to source. Check for signs of excessive vibration or exhaust smoke, which may signal a need for an expensive repower.

Community & Resources

While there is no dedicated international owner's association specifically for the 24, owners are deeply integrated into the broader Sirius-Werft community. The shipyard itself remains a primary resource; unlike many defunct brands from the 70s, Sirius-Werft is still family-owned and often provides technical advice or historical data to owners of their heritage models. German sailing forums often host technical wikis and restoration logs for the "Sirius 24/26" series, which remain popular on the European second-hand market.

The Verdict

Pros:

• Exceptional Build Quality: Built to a standard far exceeding the "throwaway" culture of early GRP production.
• Seaworthiness: A safe, predictable platform for coastal cruising and crossing open bays in heavy weather.
• Trailerability: At 2.5 meters wide, it fits within standard towing limits in most jurisdictions.
• High Resale Value: Maintains its value better than most 1970s cruisers due to the prestige of the Sirius brand.

Cons:

• Performance in Light Air: The heavy displacement makes it sluggish in light winds compared to modern sport-boats.
• Limited Headroom: Not suitable for tall sailors planning long stays on board.
• Aging Systems: Original plumbing, wiring, and engines will likely require significant updates.
