The Nauticat 35 represents a pivotal shift in the Siltala Yachts lineage, marking the Finnish builder’s transition from traditional, heavydisplacement motorsailers toward more performanceoriented pilothouse sailing yachts. Introduced in the mid1980s and designed by Kaj Gustafsson, the 35 was engineered to retain the hallmark allweather protection and voluminous living spaces of the legendary Nauticat 33, while offering a hull form capable of competitive windward performance. Unlike the boxy, highfreeboard "deckhouse" models of the 1970s, the Nauticat 35 features a more streamlined profile, a fin keel, and a skeghung rudder. This design philosophy aimed to capture a market of bluewater cruisers who demanded the comfort of an indoor helm without sacrificing the tactile feedback and speed of a modern cruising yacht.

Sailing Performance & Handling

The Nauticat 35 is a heavy-displacement cruiser that prioritizes stability and sea-kindliness over light-air agility. With a displacement-to-length ratio that leans toward the "heavy cruiser" end of the spectrum, the 35 is designed to carry its momentum through a chop, providing a dry and predictable ride in offshore conditions. The hull’s moderate beam and deep-V sections forward help mitigate slamming when heading into a head sea, a common critique of flatter-bottomed modern cruisers.

Handling is defined by the dual steering stations—an aft cockpit with a traditional pedestal and an interior wheelhouse station. Under sail, the boat is surprisingly balanced, provided the canvas is reefed early; the relatively high center of gravity inherent in pilothouse designs means the 35 rewards those who keep the boat upright. While it will not point as high as a dedicated racer, the fin keel provides sufficient lift to make effective progress to windward. In light airs, the 35 often relies on its robust marine diesel (frequently a Volvo Penta or Yanmar) to maintain cruising speeds, reflecting its "sailing yacht with motor-power" DNA. According to technical overviews from Nauticat Yachts, the transition to this hull type allowed for much higher hull speeds under power compared to the earlier full-keel motorsailers.

Interior Comfort & Variations

The interior of the Nauticat 35 is a showcase of Finnish craftsmanship, dominated by high-quality satin-finished teak and a layout that maximizes "view-port" living. The central pilothouse serves as the social hub, featuring a large U-shaped settee and a raised dining table that allows passengers to enjoy 360-degree views of the horizon while seated. This "deck saloon" arrangement is particularly valued by cruisers in higher latitudes or those who sail during the shoulder seasons.

The standard configuration includes two private staterooms. The master cabin aft is notably spacious for a 35-foot vessel, often featuring a large double berth, extensive hanging lockers, and occasionally a private en-suite head. The forward guest cabin typically utilizes a V-berth arrangement. Between the cabins, the linear or U-shaped galley is situated on a lower level but remains open to the pilothouse, ensuring the cook is never isolated from the rest of the crew.

The Nauticat 35 was eventually succeeded by the Nauticat 351, which utilized the same hull mold but introduced a redesigned transom with integrated steps and a modified rig. The 351 also saw updates to the internal cabinetry and the introduction of a more modern electrical system. Both models share the same "little ship" feel, characterized by heavy-duty hardware and excellent sound insulation around the engine compartment.

Known Issues & Buyer’s Checklist

Prospective buyers of a Nauticat 35 should focus their survey on areas common to older high-quality GRP vessels and specific pilothouse complexities:

  • Window Seals: The large toughened-glass windows in the pilothouse are a defining feature but can develop leaks over decades. Re-bedding these large panes is a labor-intensive task.
  • Teak Deck Integrity: Most Nauticat 35s were delivered with hand-laid teak decks. If the decks are original, check for thinning wood, failing caulking, and potential moisture ingress into the sub-deck, as these were often screwed down rather than just glued.
  • Dual Steering Linkage: The complexity of connecting two steering stations (usually via a combination of wire and hydraulic or mechanical linkages) requires regular inspection. Play in the wheel or stiffness in one station but not the other suggests worn bushings or cable stretch.
  • Engine Access and Maintenance: While the engine is located centrally under the pilothouse floor for weight distribution, access for major repairs can be tight. Check for service records regarding the heat exchanger and exhaust elbow, which are prone to corrosion on yachts of this vintage.

Community & Resources

Owners of the Nauticat 35 benefit from a robust and dedicated international community. The Nauticat Association, based in the UK, is one of the most active groups, providing technical archives and organizing rallies. There is also a significant owner presence in Scandinavia and North America, often centered around technical forums where members share specific advice on maintaining the Gustafsson-designed hulls.

The Verdict

The Nauticat 35 is an exceptional choice for the cruising couple who refuses to stop sailing when the weather turns foul. It bridges the gap between a traditional motorsailer and a modern cruiser, offering a level of interior luxury and protection that few 35-footers can match.

Pros:

  • Superior all-weather protection with a true internal helm.
  • Exquisite Finnish joinery and build quality.
  • High resale value due to the brand’s prestigious reputation.
  • Excellent aft cabin and 360-degree visibility from the salon.

Cons:

  • High displacement and windage make it sluggish in light winds.
  • Aft cockpit can feel somewhat cramped compared to modern open-transom designs.
  • Maintenance costs for teak decks and dual steering systems can be high.
