Able 20 Information, Review, Specs

Sailing Performance & Handling

The Able 20 is defined by its substantial displacement-to-length ratio of approximately 272, placing it firmly in the category of a "heavy cruiser" for its size class. With a ballast ratio of 40% and a traditional long keel, the boat exhibits remarkable directional stability and a "big boat" feel that is rare in 20-foot sailboats. It is notably stiff, meaning it resists heeling even in fresh breezes, providing a secure platform for families and coastal gunkholers.

The standard masthead sloop rig provides a sail area-to-displacement ratio (SA/Disp) of roughly 15.9, which, while not a racing configuration, allows for steady progress in moderate air. Handling is characterized by excellent tracking; once the sails are trimmed, the Able 20 can often be left to steer herself for brief periods. However, the trade-off for this stability is a larger turning radius and less responsiveness in tight quarters compared to modern fin-keel designs. The Maine-built versions of the boat occasionally featured a "tall rig" variant with a 26-foot mast, designed to improve light-air performance in regions with less consistent winds.

Interior Comfort & Variations

Despite its modest 20-foot length, the Able 20 provides a functional interior cabin suitable for weekend "pocket" cruising. The layout typically features a V-berth forward and two short settee berths in the main cabin area. Storage is surprisingly ample for a vessel of this vintage, with lockers tucked beneath the berths and a small area dedicated to a portable head.

Materials vary significantly between the early Miami-built hulls and the later Maine productions. The Able Marine (Maine) versions often incorporate higher-end teak trim and more sophisticated joinery, reflecting the builder's shift toward the luxury market. One notable variation mentioned by owners is the companionway configuration: while most models feature a companionway that extends down to the cockpit sole for easier access, some specific Maine-built hulls were reportedly constructed with a bridge deck, which increases structural rigidity and safety in following seas but makes ingress slightly more challenging.

Known Issues & Buyer’s Checklist

• Deck Core Integrity: Like many fiberglass boats of the 1970s and 80s, the Able 20 utilized a balsa or plywood core for the decks. Prospective buyers should perform a "tap test" with a plastic hammer to check for delamination or soft spots, particularly around high-load areas like the stanchion bases and the mast step.
• Keel-to-Hull Joint: While the long keel is integrated into the hull form, the internal ballast and the transition area should be inspected for "smiles" or stress cracking that might indicate groundings or structural fatigue.
• Water Tank Drainage: Older models occasionally suffer from plumbing issues where fresh water tanks lack a dedicated low-point drain, making winterization or cleaning difficult without a manual pump.
• Rudder Attachment: The attached rudder is a robust design, but the pintles and gudgeons should be checked for excessive play. Wear in these components can lead to a "clunking" sensation at the tiller and reduced steering efficiency.
• Wood Maintenance: Hulls built with extensive teak trim (common in the Maine variants) require regular oiling or varnishing to prevent bleaching and checking, which can lead to water intrusion behind the wood.

Community & Resources

Technical information for the Able 20 is often preserved through regional maritime history associations. The Mystic Seaport Museum is noted for maintaining archives of Loughlin Boat Works and early Able Marine documentation. For modern owners, the Chuck Paine Yacht Design website remains a high-authority resource for the design philosophy of the Maine-based yard that built these boats, even though the 20 was a Loughlin design.

The Verdict

The Able 20 is an ideal choice for the traditionalist who prioritizes stability and craftsmanship over outright speed or modern aesthetics.

Pros:

• Exceptionally stable and seaworthy for its size.
• Classic New England aesthetics that remain timeless.
• Easy to single-hand due to excellent tracking and a simple rig.
• Maine-built hulls offer a level of finish rarely seen in 20-foot production boats.

Cons:

• Heavy displacement makes it difficult to trailer without a powerful vehicle.
• The long keel limits maneuverability in crowded marinas.
• Slow performance in very light winds without the "tall rig" option.
