Stortriss Mk II Information, Review, Specs

Sailing Performance & Handling

The Stortriss Mk II is characterized by its forgiving nature and surprising stiffness for a vessel of its displacement. Weighing approximately 550 to 600 kg, with a ballast ratio often exceeding 40% (depending on the specific keel configuration), the boat handles coastal breezes with a sense of security that belies its small stature. Most Mk II models feature a fractional rig with a relatively large mainsail and a smaller, manageable jib, a hallmark of Pelle Petterson’s design language that prioritizes ease of handling for short-handed crews.

On the water, the boat exhibits high initial stability. Under sail, it tracks reasonably well due to its deep-spade rudder, though like many light-displacement boats of its era, it can become lively in a following sea. The Mk II was typically offered with a fixed fin keel, though bilge-keel versions exist for drying moorings or easier trailering. While not a racing machine, the Mk II’s hull shape—influenced by Petterson’s work on larger racing yachts—allows it to maintain momentum in light air better than many of its heavy-displacement contemporaries. Owners often report that the boat feels "tighter" and more responsive than the Mk I, largely due to reinforcements in the deck-to-hull joint and a more rigid cabin trunk.

Interior Comfort & Variations

For a vessel under 18 feet, the Stortriss Mk II offers a remarkably functional, albeit spartan, interior. The primary distinction between the Mk II and the original Mk I is the cabin house; the Mk II features a raised coachroof that extends further forward, significantly increasing the "headroom" (relatively speaking) and the volume of the interior cabin. The layout is a classic V-berth configuration that can accommodate two adults, with two narrow settee berths running aft that are best suited for children or equipment storage.

The materials inside reflect ABC Fabrikerna’s background in general leisure goods—functional, durable, and easy to clean. There is a notable absence of complex plumbing or electrical systems, which was intentional to keep the price point low and maintenance simple. The sibling models in the "Triss" family, such as the Triss Giggen and the Trissjollen, were primarily open boats or day-sailers; the Stortriss Mk II was the evolution that turned the platform into a true "overnighter." The cabin provides enough dry storage for a weekend of camping-style cruising, making it a favorite for "raid" style sailing where the boat serves as a floating tent.

Known Issues & Buyer’s Checklist

Prospective buyers of a Stortriss Mk II should focus on the structural integrity of the GRP (Glass Reinforced Plastic) components, as these boats are now approaching fifty years of age.

1. Deck Core Softness: The sandwich construction used in the deck and cabin roof can suffer from water ingress around through-bolted fittings like cleats or the mast step. High-signal areas for inspection include the area immediately surrounding the mast base, where compression can cause the fiberglass to craze or sag if the internal support has weakened.
2. Rudder Gudgeons and Pintles: The spade rudder is a common point of wear. Check for excessive "play" or slop in the rudder bushings, which can lead to a vibrating helm at speed.
3. Keel Bolt Integrity: For fin-keel models, the keel-to-hull joint should be inspected for the "smile"—a gap at the leading edge that suggests the keel bolts may need tightening or the surrounding laminate has been stressed by a grounding.
4. Window Leaks: The original rubber gaskets on the cabin windows are prone to UV degradation. Replacing these is a common first project for new owners to prevent interior wood rot.
5. Rigging Fatigue: Many Stortriss models still carry their original stainless steel standing rigging. Given the age, a forensic check for "meat hooks" or cracked swage fittings is essential.

Community & Resources

The Stortriss Mk II enjoys a dedicated following in Northern Europe. The most prominent technical resource is the Swedish Stortrissklubben, which maintains archives of original rigging diagrams and tuning guides. Historical records and original promotional materials can occasionally be found through the DigitaltMuseum, which catalogues the industrial history of ABC Fabrikerna and the maritime heritage of the Kungälv region.

The Verdict

The Stortriss Mk II remains a premier choice for sailors seeking a "minimalist" cruising experience or a robust first boat. It encapsulates a period of Swedish design where utility and seaworthiness were prioritized over luxury.

Pros:

• Ease of Transport: Light enough to be towed by a standard family car.
• Designer Pedigree: A genuine Pelle Petterson design that sails better than most 17-footers.
• Simplicity: Minimal systems mean very low annual maintenance costs.
• Safety: High ballast ratio provides a sense of security in coastal chop.

Cons:

• Confined Quarters: The cabin is suitable for sleeping but lacks the height for comfortable sitting for tall adults.
• Age-Related Wear: Most examples require some degree of fiberglass or window restoration.
• Limited Capacity: Best suited for a couple; four adults will find the cockpit and cabin cramped for anything longer than a day trip.
