Viksund 31 Goldfish MS Information, Review, Specs

Sailing Performance & Handling

The sailing characteristics of the Viksund 31 Goldfish MS are defined by its high displacement-to-length ratio and its long keel configuration. This is not a vessel designed for light-air performance or technical regattas; rather, it is a "steady-as-she-goes" cruiser that tracks exceptionally well. Under sail, the boat exhibits significant secondary stability, though it requires a stiff breeze to overcome its own inertia. The sail plan is typically modest, often featuring a ketch or sloop rig with a relatively low aspect ratio to keep the center of effort low.

Handling is characterized by a slow, predictable motion even in choppy seas, a trait inherited from its heritage as a commercial-style hull. While the boat can feel heavy on the helm when pushed hard, it excels at maintaining a course in heavy weather where lighter yachts might struggle. The transition between motoring and sailing is seamless, and most owners find that the boat performs best as a "fifty-fifty" motorsailer, using the engine to maintain headway while the sails provide lift and reduce rolling.

Interior Comfort & Variations

The interior of the 31 Goldfish MS is famously spacious for its length, a result of the high freeboard and wide beam carried well aft. The layout typically centers around a protected wheelhouse or "doghouse," which provides a dry, warm environment for the helmsman—a critical feature for high-latitude cruising. Below deck, the use of rich mahogany or teak joinery was standard, creating a traditional and cozy maritime atmosphere.

Accommodation usually consists of a V-berth in the bow and a convertible dinette in the main saloon. The 31 Goldfish was produced in several variations to suit different buyer needs. The "MS" (Motorsailer) version features the full rig, while the "Goldfish" (without the MS suffix) was often sold as a pure motor cruiser with a larger aft deck or a different cabin profile. Some variants included an aft cabin, though this was more common in the larger 34-foot siblings. The galley is generally compact but functional, designed for use at sea, and the enclosed head offers surprising headroom for a vessel of this vintage.

Known Issues & Buyer’s Checklist

Prospective buyers of a Viksund 31 Goldfish MS should focus their inspections on the longevity of the original Norwegian-built components. While the fiberglass hulls are notoriously thick and over-engineered, age-related issues are common:

• Engine Service Life: Many units were originally fitted with Volvo Penta or Sabb diesel engines. While reliable, those that have not been repowered may be reaching the end of their service life, and sourcing parts for older Sabb engines can be challenging outside of Scandinavia.
• Window Seals: The aluminum-framed windows in the wheelhouse are prone to leaking over decades. Evidence of water staining on the interior woodwork usually indicates that the seals or the frames themselves require re-bedding.
• Osmotic Blistering: Like many boats from the 1970s, some Viksunds have shown signs of osmosis. While rarely a structural threat given the thickness of the laminate, a hull survey is recommended.
• Rigging and Chainplates: Since these boats are often used primarily as motorboats, the standing rigging is frequently neglected. Check for corrosion at the chainplates and the age of the wire rigging before attempting serious offshore passage-making.

Community & Resources

The legacy of the 31 Goldfish is preserved through a dedicated community of Nordic boat enthusiasts. While there is no single international owner association, the Norwegian Viksund Owner's Facebook Group (Viksund-eierne) serves as a primary hub for technical advice, parts sourcing, and historical documentation. Additionally, information regarding the brand's evolution can be found through the current manufacturer's presence at Viksund Boats, though their focus has shifted entirely to modern motor yachts.

The Verdict

The Viksund 31 Goldfish MS is a "little ship" in every sense, offering a level of security and comfort that belies its 31-foot length. It is an ideal choice for the cruiser who values protection from the elements and a traditional aesthetic over modern racing performance.

Pros:

• Exceptional seaworthiness and heavy-weather stability.
• Protected helm station allows for a longer cruising season.
• Robust, high-quality Norwegian fiberglass construction.
• Spacious, "salty" interior with significant storage.

Cons:

• Poor light-wind sailing performance.
• Sluggish maneuverability in tight marinas due to the long keel.
• Aesthetic "sjark" styling is functional rather than sleek.
• Potential for high maintenance costs on aging original engines and systems.
