ETAP 35I Information, Review, Specs

Sailing Performance & Handling

The ETAP 35i is characterized by a balanced fractional rig and a hull shape that favors stability and predictable tracking. Unlike some of its smaller siblings that utilized a vertical steering system, the 35i is typically found with a conventional large-diameter wheel, providing the mechanical advantage needed to manage the boat’s moderate displacement. The hull features a relatively narrow entry that flares into a wide midsection, terminating in a sugar-scoop transom that was quite modern for its time.

Under sail, the 35i is noted for its stiffness. The foam-filled hull acts as a structural girder, reducing the flexing often found in single-skin boats of this vintage. This rigidity allows the rigging to stay tight, improving upwind performance. While not a light-air racer, the 35i carries its momentum well through a chop. The boat was offered with multiple keel configurations, including a deep fin for maximum lift and a shallow-draft tandem keel—a signature Etap innovation designed by Philippe Briand for other models and adapted here to allow access to thin-water anchorages without a significant loss in windward ability. According to historical technical notes from the Etap Owners Association, the 35i is particularly well-regarded for its sea-kindliness, as the insulation in the hull dampens the "slapping" noise of waves, reducing crew fatigue on long passages.

Interior Comfort & Variations

The interior of the ETAP 35i is a departure from the dark, traditional teak found in earlier yachts, opting instead for light oak or beech veneers and white laminate surfaces. This aesthetic choice, combined with the large panoramic windows in the coachroof, creates an exceptionally bright and airy saloon. Because of the double-hull construction, there is a notable absence of visible "sweating" or condensation on the interior walls, a common plague in single-skin fiberglass boats.

The layout is a standard two-cabin arrangement that prioritizes a large galley and a spacious heads compartment. The aft cabin is surprisingly generous, extending under the cockpit sole, and features a large double berth. In the saloon, the 35i often features a signature Etap design element: a curved settee and a substantial navigation station to starboard. Storage is well-considered, though slightly curtailed in some areas to accommodate the buoyancy foam. The 35i also shares DNA with its smaller sibling, the Etap 32i, and its larger successor, the Etap 37s. While the 32i feels more like a coastal hopper, the 35i provides the tankage and headroom required for extended blue-water cruising.

Known Issues & Buyer’s Checklist

Potential buyers of an ETAP 35i should focus their inspection on the integrity of the "sandwich" and the specialized hardware required for a double-hulled vessel.

1. Foam Saturation: While the closed-cell foam is designed not to absorb water, any significant hull breach or improperly sealed through-hull fitting left unaddressed for years can lead to localized delamination or "heavy" spots in the hull. A moisture meter is essential, though readings can be tricky due to the double-skin.
2. Window Seals: The large, distinctive coachroof windows are prone to leaking as the original sealant degrades. Because the windows are often integrated into the structural lines of the deck, professional re-bedding is often required to ensure the boat remains watertight.
3. Saildrive Diaphragm: Most 35i models were equipped with Volvo Penta or Yanmar engines using saildrives. The rubber sealing diaphragm has a recommended replacement interval (usually every 7 years); buyers should verify the age of this seal as failure can be catastrophic.
4. Rudder Bearings: The rudder on the 35i is a high-aspect spade. Over time, the bearings can develop play, leading to a "knocking" sensation at the helm. Inspecting the rudder stock for movement while the boat is hauled out is a priority.

Community & Resources

The ETAP 35i benefits from a highly organized and technical international owner base. The Etap Owners Association (UK-based) is the primary repository for technical manuals, wiring diagrams, and specific advice on maintaining the unsinkable hull. Additionally, the Dutch Etap Club remains active, reflecting the brand’s massive popularity in Northern Europe where its insulation properties are most valued.

The Verdict

The ETAP 35i is a sophisticated, over-engineered cruising yacht that offers a level of security few other production builders can match. It is an ideal choice for sailors who prioritize safety and interior comfort over raw racing speed.

Pros:

• Unsinkable Construction: Provides immense peace of mind for offshore or family cruising.
• Superior Insulation: The double-hull prevents condensation and offers a quiet, temperature-stable cabin.
• Bright Interior: The light wood finishes and large windows avoid the "cave-like" feel of older cruisers.
• Structural Rigidity: The foam-core hull makes for a very stiff boat that holds its tune well.

Cons:

• Maintenance Complexity: Repairs to the double-hull after a collision can be more technical and expensive than single-skin GRP.
• Weight: The extra skin and foam make it heavier than some contemporary performance cruisers.
• Storage Trade-off: Some locker volume is sacrificed to provide the necessary buoyancy foam.
