Hull and Construction
The Nauticat 35 is built to a standard that reflects the quality Finnish boatbuilding has long been associated with. Hulls are solid fiberglass while decks and superstructure are cored fiberglass composites, a combination that delivers structural stiffness without unnecessary weight aloft. Even given the large windows and numerous opening hatches that define the pilothouse character, leaks are described as rare. Interior joinerwork is excellent and access for service and maintenance is better than most production boats — a practical virtue that pays dividends over a long cruising life.
The hull form is moderately beamy at eleven feet four inches, with a near-vertical transom and a bow rake that gives the profile its distinctive wedge-like character. The sheerline is kept quite flat and the raised quarterdeck pulls the eye up, while the careful use of a broad wale-stripe, cove-stripe, and double boot-stripe visually draws out the hull and moderates the apparent freeboard. Two keel configurations are offered: a shoaler four-foot-eight draft and a deeper five-foot-six option, both with external lead ballast. The displacement-to-length ratio sits at 282 — conservative without being heavy.
Rig and Sailing Performance
Calling the Nauticat 35 a motorsailer undersells her as a sailor; calling her a pure sailboat ignores the design intent. Siltala and most reviewers prefer the term "pilothouse sailing yacht," and the underwater shape supports it. The underbody features an easily driven hull with a well-designed low-aspect fin keel and a balanced rudder with partial skeg, giving her a tacking ability that does not require the engine. The rudder carries a pronounced leading-edge fillet on the partial skeg, improving directional stability in a seaway.
Most examples were rigged as sloops, though some owners have added an inner forestay to carry a second headsail. The sail area-to-displacement ratio is modest — calculated at 15.3 on the number two genoa — and the addition of a 120% to 150% genoa will help with light-air performance. The mast is stepped forward of the pilothouse, a layout that keeps sail-handling operations away from the helmsperson and away from the coach roof. A rigid vang assists with mid-boom sheeting and keeps the boom under control on a run. Steering is hydraulic throughout, which takes some getting used to as the feel is almost eliminated, though sailing valves are fitted to restore some feedback.
Pilothouse and Accommodations
The raised pilothouse is the defining feature of the Nauticat 35 and the reason most owners choose her. Inside steering is a genuine pleasure in cold or wet weather, and visibility is excellent forward and to both sides from the inside helm — a point not to be taken for granted in this class, where some competitors render the inside station nearly useless. The raised dinette seats four in comfort and is positioned to offer decent sight lines through the pilothouse windows.
The below-decks arrangement makes efficient use of the hull volume. The aft master stateroom is entered from the main saloon to starboard and carries a double berth and a dedicated head. Forward, the galley runs to starboard while a second head sits to port, with a V-berth stateroom at the bow. There are comfortable accommodations for two couples, though the forward starboard berth is partially compromised where the galley counter encroaches on its forward section. Overall, for a thirty-five-footer, the sense of space is remarkable.
Mechanical Systems and Range
The standard auxiliary is a 43-horsepower Volvo Penta diesel with a 2.4-to-1 reduction gear driving a solid three-blade propeller, capable of pushing the boat to hull speed without strain. Some later examples were fitted with a 50-horsepower Yanmar as an alternative. Fuel capacity is slightly more than 90 gallons, giving an impressive range of more than 500 miles under power, which suits the motorsailer role well on long coastal passages where light winds or adverse conditions might call for extended motoring. Water tankage runs to 132 gallons. Hydraulic steering is fitted throughout, managed by a Teleflex/Capilano system.
Deck Layout and Cockpit
The deck plan manages its competing demands reasonably well. The forward cabin trunk is low enough to provide a nearly flush deck working space, and side decks are wide enough for safe passage past the pilothouse. The mast placement forward of the pilothouse improves the working situation for crew handling sail. The cockpit, however, is the one area where compromises are most evident: perched above the raised quarterdeck, the seating is narrow, the seat backs lack height for real support, and they end at the steering pedestal — leaving the helmsperson without back support during a watch. This is unlikely to change the calculus for buyers already committed to this style of cruising, but it is worth understanding before sea trials.
The Verdict
The Nauticat 35 is a specialist's boat, built for cruising sailors who prioritize shelter, range, and interior comfort over performance metrics or racing pedigree. Finnish construction quality is evident throughout, from the solid fiberglass hull to the joinery to the attention paid to practical maintenance access. She is not a boat to be judged against a sloop of similar length; she is a boat to be judged against the conditions for which she was designed — extended cruising in variable or demanding weather — and on those terms she delivers.
Pros
- Exceptional Finnish build quality; solid hull, cored deck, rare leaks
- Genuine pilothouse with excellent visibility from the inside helm
- Two-couple accommodation in a thirty-five-foot hull
- Easily driven underbody; sails without the engine in most conditions
- 500-mile-plus motoring range from standard tankage
- Better service and maintenance access than most production boats of the era
Cons
- Hydraulic steering eliminates helm feel; takes adjustment for sailing purists
- Cockpit seating is narrow, shallow-backed, and leaves the helmsperson without support
- Modest sail area-to-displacement ratio demands a large genoa in light air
- Niche appeal means finding buyers takes longer than for mainstream cruising designs
