The Colin Archer Roskilde 35 is a robust, steelhulled doubleender that exemplifies the "Redningsskøyte" (rescue craft) design philosophy pioneered by the legendary Norwegian naval architect Colin Archer. Often constructed in specialized Dutch and Danish yards, such as Scheepswerf De Vries in Lemmer, this model is specifically engineered for longdistance bluewater cruising in demanding environments like the North Sea. Unlike the original wooden pilot boats of the 19th century, the Roskilde 35 translates these traditional lines into modern steel construction, often featuring a roundbilged clinkerstyle hull that offers exceptional structural rigidity. It typically carries a heavy displacement of approximately 11 to 12 tonnes on a 10.7meter (35foot) frame, emphasizing stability and seakindliness over the highspeed performance of contemporary lightdisplacement cruisers.

Sailing Performance & Handling

The Roskilde 35 is defined by its heavy displacement and full-keel configuration, often supplemented by bilge keels that allow the vessel to stand upright in drying moorings. This design prioritizes "Safety First," a philosophy explored in detail by Practical Sailor, which notes that while Colin Archer-inspired designs may struggle with light-air performance and weatherliness, they excel in heavy weather. With a length-to-beam ratio of approximately 3.05, the hull is relatively "spacy," providing a stable platform that resists the "hobby-horsing" motion common in finer-ended vessels.

Under sail, the Roskilde 35 is most commonly found in ketch or cutter-rig configurations. The split rig allows for versatile sail plans, making it easier for a small crew to manage sail area as the wind increases. Handling is characterized by high directional stability; once trimmed, the boat tracks with remarkable precision, reducing the load on the helm or autopilot. However, due to its significant wetted surface area and heavy ballast, it requires a stiff breeze to reach its hull speed, and tacking angles are typically broader than those of a modern fin-keel yacht.

Interior Comfort & Variations

The interior of the Roskilde 35 is traditionally finished, usually featuring extensive mahogany or teak joinery that reflects its heritage. With a generous headroom of approximately 1.95 meters (6'4"), the cabin feels surprisingly spacious for a 35-foot double-ender. Most variants utilize a pilothouse or "deck salon" layout, providing 360-degree panoramic views and a secondary internal steering position, which is invaluable for cold-weather cruising or long passages in inclement weather.

The standard layout typically includes a forward V-berth, a central saloon with a U-shaped settee, and a well-equipped galley. A defining feature of many Roskilde 35 builds is the inclusion of two distinct cabins and a protected wheelhouse. Sibling models, such as the slightly smaller Roskilde 32, offer a more compact version of this layout, while specialized versions like the Roskilde 35 "Kielmidzwaard" (centerboard version) were built to allow access to shallow coastal waters and inland canals.

Known Issues & Buyer’s Checklist

Purchasing a steel vessel of this age and pedigree requires a specialized inspection focusing on metal integrity and technical systems.

  • Steel Corrosion & Coating: The primary concern for any Roskilde 35 is the condition of the steel hull. Buyers should inspect the "bilge keels" and the internal hull sections beneath the floorboards, where trapped condensation or water can lead to localized "pitting." A professional ultrasonic thickness test is essential to verify that the hull plating (typically 4mm to 5mm) remains within safe tolerances.
  • Teak Deck Integration: Many Roskilde 35s were fitted with teak decks over the steel substructure. If the teak is screwed rather than glued, moisture can penetrate the screw holes, leading to rust between the wood and the steel deck.
  • Engine Access & Maintenance: These boats are often equipped with Vetus or Nanni diesel engines (ranging from 40 to 62 hp). Due to the heavy displacement, the engine often works hard; inspectors should check the heat exchanger and exhaust elbow for scale buildup, as well as the hydraulic steering lines common in the dual-station (cockpit/pilothouse) setups.
  • Rudder & Skeg Bushings: The heavy, outboard-mounted or skeg-hung rudder is a hallmark of the design. Buyers should check for play in the rudder bushings, which can lead to vibration or heavy steering over time.

The Verdict

The Colin Archer Roskilde 35 is a specialized tool designed for those who value absolute seaworthiness and traditional aesthetics over modern racing performance.

Pros:

  • Exceptional Seaworthiness: Built to withstand ocean conditions that would turn back lighter coastal cruisers.
  • All-Weather Comfort: The pilothouse configuration and high-quality wooden interior provide a cozy, protected environment for high-latitude sailing.
  • Stable Tracking: The long keel ensures excellent directional stability and a comfortable motion at sea.

Cons:

  • Limited Light-Air Performance: Requires significant wind to overcome its heavy displacement and wetted surface.
  • High Maintenance: Steel hulls require diligent paint maintenance and cathodic protection to prevent corrosion.
  • Weight & Maneuverability: Difficult to handle in tight marinas due to its weight and long-keel turning radius.
