The ETAP 24i represents a refined evolution of the Belgian shipyard’s "unsinkable" philosophy, designed by Von Ahlen Yacht Design to bridge the gap between nimble trailer-sailers and dedicated coastal cruisers. Introduced in the late 1990s as a successor to the popular ETAP 23, the 24i was a modernization of the fleet, featuring a more vertical stem, a longer waterline, and a sleek, contemporary coachroof. The hallmark of the vessel remains its double-skinned hull construction; the void between the inner and outer fiberglass molds is filled with closed-cell polyurethane foam. This design provides sufficient buoyancy to keep the boat—and its crew—afloat even if the hull is breached, while simultaneously providing exceptional thermal and acoustic insulation that significantly reduces cabin condensation.

Sailing Performance & Handling
The ETAP 24i is characterized by its stiffness and predictable handling, even when pushed in coastal chop. With a displacement of approximately 1,820 kg, it carries a relatively high ballast ratio, which contributes to its reputation as a "stiff" boat that stands up well to its canvas. Most 24i models were equipped with the patented Etap tandem keel—a twin-bulb configuration that provides the lift and performance of a deeper fin keel while maintaining a shallow draft of just 0.85 meters. This makes the boat an exceptional choice for thin-water cruising in regions like the East Coast of England or the Chesapeake Bay.
Under sail, the boat is typically rigged as a 7/8 fractional sloop. The lead of the lines back to the cockpit and the inclusion of a self-tacking jib on many units make it a favorite for solo sailors. While it lacks the raw acceleration of a pure sportboat, it maintains momentum well. According to technical insights from Von Ahlen Yacht Design, the hull’s volume distribution was specifically calculated to minimize the shift in the center of buoyancy when heeled, resulting in a balanced helm that requires minimal effort from the pilot or an autopilot system.
Interior Comfort & Variations
Inside, the 24i benefits immensely from its double-hull construction, which replaces the rough unfinished fiberglass found in many yachts with a smooth, wipe-clean internal liner. The layout is remarkably ambitious for a 24-foot hull, offering four berths—a double V-berth forward and two long settees in the saloon. Unlike its smaller sibling, the ETAP 21i, the 24i features a dedicated, enclosed heads compartment located to starboard, a luxury rarely found in boats of this size that can still be legally trailered in many jurisdictions.
The cabinetry typically utilizes light woods like beech or oak, which, combined with the large panoramic windows, creates an airy, voluminous feel. The galley is compact but functional, featuring a two-burner stove and a sink with pressurized water. Variation in the model line was primarily focused on the keel (tandem vs. deep fin) and the propulsion system; while many were fitted with 10hp Volvo Penta or Yanmar saildrive diesels, some owners opted for high-thrust outboards mounted on a transom bracket to save weight and simplify maintenance.
Known Issues & Buyer’s Checklist
- Saildrive Diaphragm: For models equipped with an inboard diesel, the Volvo Penta or Yanmar saildrive rubber seal has a manufacturer-recommended replacement interval (typically 7–10 years). Buyers should verify the age of this seal, as failure can compromise the "unsinkable" security of the vessel.
- Foam Saturation Check: While the closed-cell foam used by Etap does not "soak up" water like a sponge, long-term leaks from deck hardware can occasionally lead to moisture becoming trapped between the hulls. A moisture meter check on the inner skin, particularly around the chainplates and stanchion bases, is recommended.
- Rudder Play: The 24i uses a high-aspect spade rudder. Owners have occasionally reported wear in the rudder bushings, leading to a "knocking" sensation at the helm. This is a standard maintenance item but requires the boat to be hauled for repair.
- Window Crazing: The large acrylic windows that give the 24i its modern look are prone to UV crazing over decades. Prospective buyers should inspect the seals for signs of previous water ingress, which can hide behind the interior liner.
Community & Resources
The ETAP 24i is supported by a robust network of European and international owners. The Etap Owners Association serves as the primary technical repository for the brand, offering digitized manuals and rigging guides that are essential for maintaining these boats now that the original shipyard is no longer in production. In Germany and the Benelux region, where the boats were most popular, local yacht clubs often host "Etap-only" rallies, reflecting the brand's enduring cult status.
The Verdict
The ETAP 24i is a masterclass in small-boat engineering, offering a level of security and interior refinement that few manufacturers have attempted to replicate. It is the ideal vessel for the safety-conscious sailor or the cruising couple looking to downsize without sacrificing the comforts of a larger yacht.
Pros:
- True "unsinkable" safety rating provides immense peace of mind.
- Exceptional insulation results in a dry, quiet, and mold-free interior.
- Tandem keel allows for deep-water performance with shallow-water access.
- High build quality ensures strong resale value.
Cons:
- The double-hull construction makes accessing the backside of deck hardware difficult for repairs.
- Slightly heavier than non-insulated competitors, requiring more wind to reach hull speed.
- Availability is limited, particularly in the North American market.
