The Colin Archer 35 Roskilde is a robust, double-ended blue-water cruiser that embodies the "redningsskøyte" (rescue boat) philosophy translated into modern materials. Primarily built by the Danish shipyard Skovgaard & Frydensberg during the 1970s and 1980s, the Roskilde 35 was a departure from the traditional wooden construction of its ancestors, utilizing a heavy-duty glass-reinforced plastic (GRP) hull to offer the legendary seaworthiness of a Colin Archer design with significantly reduced maintenance. This model is a true "heavyweight" in the 35-foot category, designed specifically to handle the unforgiving conditions of the North Sea and North Atlantic. While many Colin Archer designs are custom-built, the Roskilde 35 represents a semi-production effort to standardize the lines of the famous Norwegian designer for the cruising market. The hull is characterized by a deep full keel, a traditional canoe stern, and a massive beam that provides immense internal volume for a vessel of its length.

Sailing Performance & Handling
The sailing characteristics of the Roskilde 35 are defined by its high displacement and significant wetted surface area. With a displacement-to-length ratio that firmly places it in the "heavy cruiser" category, this is not a boat that excels in light airs or tight windward work. Instead, it is a momentum-based sailer that finds its stride in Force 4 winds and above. The full keel provides exceptional directional stability, allowing the boat to track straight for hours with minimal helm correction—a trait highly prized by single-handed sailors and long-distance cruisers.
Most Roskilde 35s were rigged as cutters, a configuration that allows for a versatile sail plan. According to technical discussions maintained by the Colin Archer Club, the design benefits from the ability to reef down to a staysail and deep-reefed main while maintaining balance in heavy weather. While the boat is notoriously slow to stay (tack) due to its long keel—often requiring a back-set staysail to pull the bow through the wind in choppy seas—it offers a motion at sea that is far more comfortable and "kind" than modern fin-keeled designs. It does not slam into head seas but rather parts them, though the heavy bow can be "wet" in certain conditions.
Interior Comfort & Variations
Inside, the Roskilde 35 offers a level of volume rarely seen in 35-footers from the era, largely due to its generous beam and high freeboard. The interior is typically finished in traditional Scandinavian style, utilizing high-quality mahogany or teak joinery that creates a "ship-like" atmosphere. The standard layout features a deep "U-shaped" galley to port, which is exceptionally secure for cooking at sea, and a dedicated navigation station to starboard.
The main salon usually employs two longitudinal settees with a central folding table, which can serve as excellent sea berths. One of the defining characteristics of the Roskilde 35 is the headroom, which remains generous throughout most of the cabin. Variations in the interior are common, as many were finished by different yards or knowledgeable owners. Some versions include a dedicated pilot berth behind the nav station, while others prioritize a larger head compartment. The V-berth in the bow is typically spacious, though the narrowing of the canoe stern limits storage in the extreme aft compared to modern wide-transom cruisers. Sibling models built by the same yard include the smaller Roskilde 32 and the larger Roskilde 40, both of which share the same GRP-heavy-displacement DNA.
Known Issues & Buyer’s Checklist
Prospective buyers of a Roskilde 35 should focus their inspections on the unique challenges of aging heavy-displacement GRP hulls.
- Iron Ballast Encapsulation: Many Roskilde models used encapsulated iron ballast. If water penetrates the laminate (often through the keel shoe or deep bilge), the iron can rust and expand, potentially cracking the fiberglass. Buyers should look for "weeping" rust stains or bulges along the keel.
- Teak Deck Integrity: A common feature of these Danish-built boats was a thick teak-over-fiberglass deck. These were often fastened with hundreds of screws; as the bungs wear and sealant fails, leaks into the sub-deck core (often balsa or plywood) can cause significant structural rot.
- Chainplate Corrosion: The chainplates on the 35 are often heavy steel straps. Due to their age, the sections passing through the deck should be pulled and inspected for crevice corrosion, which is a common failure point on blue-water boats of this vintage.
- Rudder Bushings: The massive barn-door rudder is hung on the trailing edge of the keel. Inspect the pintles and gudgeons for play, as replacing these bronze or stainless fittings requires significant labor.
Community & Resources
The primary authority for these vessels is the Colin Archer Club, an international organization based in the Netherlands that maintains a registry of GRP and wooden Archer designs. They provide a wealth of technical drawings and historical context for the Roskilde variants. In Scandinavia, the Danish and Norwegian maritime museums occasionally host archives related to Skovgaard & Frydensberg, though much of the day-to-day technical support is found within the "Klassisk GRP" enthusiast circles in Northern Europe.
The Verdict
The Colin Archer 35 Roskilde is an uncompromising vessel built for the sailor who prioritizes safety and stability over speed and agility. It is a "forever boat" capable of weathering storms that would force lighter cruisers to seek shelter.
Pros:
- Extreme structural integrity and seaworthiness.
- Excellent tracking and heavy-weather stability.
- Immense interior volume and traditional craftsmanship.
- Highly respected pedigree for long-distance cruising.
Cons:
- Sluggish performance in light winds.
- Difficult to maneuver in tight marinas due to the long keel and prop walk.
- Potential for high-cost repairs if teak decks or encapsulated ballast have been neglected.
