The Zonda Z24 DS (Daysailer) represents a strategic evolution for the Argentine builder Zonda Yachts, previously known as Astilleros del Sur. Designed by the renowned naval architect Pablo Mastracchio, this 23.8-foot monohull was engineered to bridge the gap between a high-performance sportboat and a manageable family cruiser. According to Zonda Yachts, the model was developed with a philosophy of "simplicity, comfort, and enjoyment," prioritizing features that allow for single-handed operation without compromising the structural integrity required for spirited racing. Since its international debut, the vessel has gained significant traction in the North American market through its distributor Auster Yachts, eventually securing the title of "Best Recreational Racer" in 2024 by Sailing World Magazine. Built on a legacy of Argentine craftsmanship that dates back to 1998, the Z24 DS is the modern successor to the earlier Mastracchio 24.5 and a sibling to the larger Z28 DS, sharing the same focus on modern lines and a trailerable footprint.

Sailing Performance & Handling
Under sail, the Z24 DS is characterized by a "recreational sportboat" feel that emphasizes responsiveness over brute force. The standard fractional sloop rig features a self-tacking jib on a radiused track, which facilitates effortless tacking without leaving the helm. For those seeking more speed, the "Performance" variant offers a taller mast and an expanded sail area of 312 square feet—a significant jump from the standard 220 square feet—dramatically increasing the sail area-to-displacement ratio.
The hull’s stability is derived from a 1,100-pound bulb keel, providing a ballast ratio of nearly 40% on a 2,860-pound displacement. This configuration, combined with a deep, carbon-skinned rudder, allows the boat to track exceptionally well upwind. Test reports from Sailing World Magazine noted that the rudder remains balanced and authoritative even in gusts of 10 to 15 knots, resisting the tendency to spin out. The lifting keel mechanism—a hallmark of Zonda’s "boatyard spirit"—allows the draft to be reduced from 4'7" to just 1'8", making the Z24 DS uniquely capable of beaching or navigating thin-water estuaries while remaining fully trailerable.
Interior Comfort & Variations
Despite its classification as a daysailer, the Z24 DS features a fully molded GRP interior that adds structural rigidity and a clean, low-maintenance aesthetic. The cabin provides a surprising amount of utility for a 24-foot vessel, including a double V-berth forward and a dedicated quarter berth on the starboard side. While headroom is inherently limited by the boat's low-profile sporty silhouette, the space is sufficient for sheltering from weather or occasional weekend overnights.
Interior materials often feature guatambu wood trims, providing a warm contrast to the white gelcoat finishes. The layout includes stowage areas with molded covers and a designated recess for a compostable toilet, a thoughtful inclusion for families. Variations of the model include the "Regatta" version, which often strips away certain cruising amenities to shed weight, and the "Day Sailer" version, which maximizes cockpit comfort with Sunbrella-upholstered backrests and refined deck hardware. Its predecessor, the M24.5, laid the groundwork for this layout, but the Z24 DS updated the design with larger cabin windows and a more ergonomic companionway.
Popular Mentions & Media
The Z24 DS achieved its highest profile when it was named "Best Recreational Racer" for 2024 by the judges at Sailing World. The award highlighted the boat's construction quality, specifically its split-hull lamination process which ensures the keel box is integrated into the primary structure rather than being a secondary bond. The vessel has also been featured in numerous South American nautical publications, such as Barcos Magazine, which documented the model’s launch in 2020 as a "revolutionary concept" within the Argentine sailing scene.
Known Issues & Buyer’s Checklist
As a relatively new model under the Zonda brand, the Z24 DS has a clean record, but buyers should focus on the specific mechanical systems that enable its versatility.
- Keel Winch Mechanism: The lifting bulb keel relies on a manual winch system nested near the companionway. Buyers should inspect the cable and winch for smooth operation, as salt buildup or lack of lubrication can lead to seizing in the keel trunk.
- Rudder Housing: The carbon-skinned rudder is held in a lifting cassette. Ensure the quick-release skewers and the carbon blade itself are free of chips or stress cracks, especially if the boat has been frequently trailered or operated in shallow waters.
- Center Seam Integrity: Because the boat is built in split halves that are laminated together at the centerline, a thorough inspection of the interior GRP bonding along the keel box area is recommended to ensure no manufacturing voids exist.
- Core Inspection: The deck uses a sandwich laminate with honeycomb vacuum construction. While this provides excellent stiffness-to-weight, any unauthorized hardware installations by previous owners should be checked for proper sealing to prevent water ingress into the core.
Community & Resources
The primary hub for technical support and community interaction is the Zonda Yachts Group in San Fernando, Argentina. In the United States, owners typically coordinate through Auster Yachts, which manages the warranty and parts distribution for North American hulls. While there is no standalone international class association yet, many Z24 DS owners participate in "Recreational Racer" classes and mixed-fleet regattas, sharing maintenance tips through regional sailing clubs and the builder’s direct communication channels.
The Verdict
Pros:
- Exceptional "hose-and-go" simplicity for solo sailors.
- Trailerable design with a rapid-deploy mast and lifting appendages.
- Award-winning performance profile that punches above its weight in light air.
- High-quality GRP construction with an integrated, molded interior.
Cons:
- Interior headroom is limited, suitable only for "camping" style overnights.
- The lifting keel winch requires regular maintenance to remain reliable.
- High ballast-to-displacement ratio makes the boat stable but less likely to plane than some pure sportboats.
