AB 23 Information, Review, Specs

Sailing Performance & Handling

The AB 23 is widely recognized for its "big boat" feel, a trait common among Abílio Barros designs. With a displacement of approximately 1,500 kg and a ballast ratio near 40%, the vessel exhibits considerable stability in a breeze. Under sail, it is a balanced performer; while not exceptionally fast in light airs due to its conservative sail area-to-displacement ratio (estimated around 17), it excels when the wind picks up, maintaining a steady track and inspiring confidence in a chop.

According to technical reviews and owner accounts often cited on technical maritime platforms like Popa.com.br, the AB 23 handles predictably on a beat. Its fixed keel (typically drawing 1.30 meters) provides enough lateral resistance to allow the boat to point reasonably well, though its relatively full sections can lead to some slamming in short, steep waves. Off the wind, the boat remains stable and easy to steer, making it a favorite for solo sailors or small families.

Interior Comfort & Variations

For a 23-foot vessel, the AB 23 offers a remarkably functional interior that maximizes its 2.50-meter beam. The layout is a standard "pocket cruiser" configuration: a forward V-berth, two longitudinal settees in the main salon that double as single berths, and a compact galley area near the companionway. Headroom is modest, usually ranging between 1.50 and 1.55 meters, which necessitates a "crouched" posture for taller adults but provides a cozy environment for overnight stays.

The AB 23 was part of a tiered family of designs by Abílio Barros that shared a clear aesthetic and structural DNA. Its siblings include the AB 20, a more compact version intended for sheltered waters, and the AB 28, a significantly more spacious and seaworthy cruiser capable of longer offshore passages. While the AB 23 was the most popular of the three, the 28-foot variant is often sought after by those transitioning from the 23 who desire more standing headroom and a separate head compartment.

Known Issues & Buyer’s Checklist

Prospective buyers of an AB 23 should conduct a thorough inspection of several key structural areas typical of fiberglass boats from this era:

• Deck Delamination: Like many boats of its vintage, the AB 23 uses a sandwich construction for the deck. Soft spots, particularly around the mast step and chainplates, are common indicators of moisture ingress and core rot.
• Keel-to-Hull Joint: Check for the "smile" at the leading edge of the keel. Corrosion of the keel bolts can occur if maintenance has been neglected, especially in boats kept in saltwater.
• Rudder Bearings: Owners frequently report play in the rudder assembly. Inspect the pintles and gudgeons (or internal bearings, depending on the specific build year) for wear that could lead to vibration at higher speeds.
• Rigging Age: Many AB 23s still carry their original or very old standing rigging. A technical survey should prioritize the swage fittings and the condition of the mast step compression post.

Community & Resources

The AB 23 remains a staple of the sailing community in Southern Brazil, particularly in the regions of Rio Grande do Sul and Santa Catarina. Technical support and historical data are primarily maintained through the Associação de Veleiros de Oceano (Ocean Sailing Association) and regional technical hubs like Popa.com.br, which serves as a technical wiki and forum for owners of these classic Brazilian designs.

The Verdict

The AB 23 is a quintessentially sturdy pocket cruiser that offers an affordable entry into the world of keelboat sailing. While it lacks the interior volume and speed of modern 23-footers, its build quality and predictable handling make it a reliable choice for coastal exploration.

Pros:

• Predictable and forgiving handling in heavy weather.
• Sturdy fiberglass construction with a high ballast ratio for stability.
• Strong regional community support and spare part availability in South America.

Cons:

• Limited headroom and cramped interior for extended cruising.
• Relatively slow performance in light wind conditions.
• Susceptible to typical age-related issues such as deck delamination.
