The ETAP 23iL is a sophisticated evolution of the Belgian builder’s philosophy, representing one of the most refined expressions of the "unsinkable" trailer-sailer concept. Launched in the mid-1990s as an updated iteration of the successful Etap 23 and 23i, the "iL" (often denoting "Improved" or "Luxury" specifications) was designed by Jac. de Ridder to offer a coastal cruising experience that prioritized safety and thermal comfort without the Spartan compromises typical of 23-footers. Built with the brand’s signature double-skin hull filled with closed-cell polyurethane foam, the vessel is certified as unsinkable, a feature that also provides exceptional acoustic and thermal insulation. This construction method distinguishes the 23iL from its contemporary competitors, such as the Beneteau First 235 or the Jeanneau Sun Fast 24, by creating a hull that is remarkably stiff and resistant to the condensation issues common in single-skin fiberglass boats.

Sailing Performance & Handling

The sailing characteristics of the ETAP 23iL are defined by its versatile keel configurations and a relatively high ballast ratio, which lends the boat a "big boat" feel in a seaway. Most models feature either a shallow-draft tandem keel or a vertical lifting keel. According to technical assessments often cited by the Etap Yachting design archives, the tandem keel—a signature Jac. de Ridder innovation—allows for a draft of approximately 0.70m to 0.85m while maintaining the lift and windward performance of a much deeper fin.

Under sail, the 23iL is known for its directional stability and predictable manners. The fractional rig is easy to tune, and the boat typically carries its canvas well into Force 4 or 5 before requiring a reef, thanks to the inherent stability provided by its hull form and internal foam buoyancy. While the extra weight of the double hull (displacing approximately 1,400kg to 1,500kg depending on the engine configuration) prevents it from being a light-wind "flyer," it offers a sense of security and "sea-kindliness" that makes it a favorite for family coastal hops. The rudder remains responsive even when heeled, though the lifting keel versions require careful tensioning of the lifting mechanism to prevent "clunking" while underway.

Interior Comfort & Variations

Inside, the ETAP 23iL maximizes its 23-foot (7.10m) length through a clever, open-plan layout that benefits aesthetically from the absence of visible hull ribs or stringers, which are hidden between the two fiberglass skins. The interior is characterized by light-colored oak or mahogany joinery and a clean, modular feel. It typically offers four berths: a double V-berth forward (often partially separated by a privacy curtain or bulkhead) and two longitudinal settees in the saloon.

The "iL" designation brought refinements to the galley and storage areas compared to the original 23 model. It usually features a slide-out galley unit or a fixed compact block with a two-burner stove and a small sink. Headroom is approximately 1.50m (4'11"), which, while not standing height for most adults, is generous for a boat that can be easily trailered. The insulation provided by the foam core makes the 23iL significantly quieter and warmer than its peers, effectively extending the sailing season into the shoulder months of spring and autumn. Sibling models include the original Etap 23, the more basic 23i, and the slightly larger Etap 24i, which features a more modern vertical stem and an integrated swim platform.

Known Issues & Buyer’s Checklist

While the ETAP 23iL is built to a high standard, there are specific technical areas that a prospective buyer should investigate:

  • Keel Lifting Mechanism: On models equipped with the lifting keel, the stainless steel spindle and the bronze nut can wear over time. If the keel is difficult to raise or shows significant play (wobble) when down, it may require a specialized overhaul.
  • Foam Core Integrity: Although the closed-cell foam is designed not to absorb water, a hull that has suffered significant impact or poorly sealed through-hull fittings can allow moisture to enter the cavity between the skins. A moisture meter check is recommended, particularly around the keel trunk and rudder post.
  • Window Seals: The panoramic windows are a stylistic hallmark of the "i" series but can develop leaks after decades of UV exposure. Resealing these requires careful removal to avoid cracking the acrylic.
  • Rudder Bearings: The Etap 23iL uses a transom-hung or partially balanced rudder. Check for play in the bushings, which can lead to vibration at higher speeds.
  • Outboard vs. Inboard: While many 23iLs utilize an outboard in a well or on a bracket, some were fitted with small Saildrive diesels (like the Volvo Penta MD2010). If an inboard is present, the Saildrive diaphragm seal should be checked for its replacement date, as insurance companies often require these to be changed every 7–10 years.

Community & Resources

The ETAP 23iL benefits from a very active and technically minded owner base, primarily centered in Europe. The Etap Club (primarily Dutch-based but with English resources) and the UK-based Etap Owners Association provide invaluable technical drawings, manuals, and advice on sourcing parts for the unique double-skin construction. These associations are the primary source for documentation no longer available from the original shipyard.

The Verdict

The ETAP 23iL remains one of the most logical choices for a safety-conscious sailor looking for a high-quality, trailerable cruiser. Its unsinkable construction and superior insulation set it apart in the used market, though these features come with a weight penalty that limits its racing potential.

Pros:

  • Unsinkable Construction: Provides unmatched peace of mind for coastal and cross-channel passages.
  • Thermal Comfort: The double hull eliminates condensation and retains heat better than single-skin boats.
  • High Resale Value: Etap yachts historically hold their price better than many high-volume production boats.
  • Versatile Draft: The tandem keel option allows for shallow-water exploration without sacrificing too much windward ability.

Cons:

  • Weight: Heavier than many 23-footers, requiring a more substantial towing vehicle.
  • Limited Headroom: Taller sailors will find the 1.50m clearance restrictive for extended stays.
  • Maintenance Complexity: Repairing damage to a double-skin hull requires more specialized knowledge than standard fiberglass repair.
