Privateer 20 Information, Review, Specs

Sailing Performance & Handling

The Privateer 20 is often described by experienced owners as a "dinghy with a lid," reflecting its light displacement and reactive handling. With a Displacement/Length (D/L) ratio of approximately 147, the hull is relatively light for a cruiser, allowing it to accelerate quickly in light airs. However, its stability relies significantly on its lifting keel (centerboard) and internal ballast. Technical evaluations, such as the Oliver Shaw Review, highlight that the boat is best suited for coastal and inland waters, with a capsize screening formula of roughly 2.41—well above the threshold typically recommended for blue-water ocean racing.

Under sail, the boat can be prone to significant weather helm if the lifting keel is not handled correctly. Unlike modern performance yachts where the keel is simply "down" for upwind work, the designer’s original intention was for the centerboard to act as a trim tab to balance the aft skeg. In standard conditions, sailing with the board only halfway down often improves helm balance. The gaff cutter rig, while complex to tune, offers a flexible sail plan; the ability to "scandalize" the mainsail (dropping the peak) allows for rapid depowering in squalls. Conversely, in light winds, the addition of a topsail can significantly boost the boat’s modest sail area-to-displacement ratio of 15.6.

Interior Comfort & Variations

For a vessel with a hull length of just under 20 feet, the interior arrangement is remarkably ambitious, offering four berths in a single open-plan cabin. The layout typically features a V-berth forward and two long quarter berths extending under the cockpit seats. Headroom is limited to a sitting position, a necessary compromise to maintain the boat's low-profile, traditional silhouette.

Construction quality varies slightly between the early Small Craft of Blockley models and later versions. The interior is largely GRP-molded with timber accents, providing a clean but basic environment. Storage is notoriously sparse, with much of the "useful" space taken up by the centerboard trunk which bisects the cabin. Most examples were equipped with a rudimentary galley shelf for a two-burner stove and a dedicated locker for a chemical toilet, though privacy is non-existent as the head is usually unscreened. Owners often modify the cabin to improve ventilation, as the original hinged companionway hatches were known for poor sealing and a lack of adjustable "cracked" positions for overnight airflow.

The Privateer 20 is the larger sibling of the Norman Howard-designed Shipmate Senior. While the Shipmate Senior is a smaller dayboat variant, the Privateer 20 adds the clipper bow and the volume necessary for weekend cruising.

Popular Mentions & Media

The Privateer 20 maintains a dedicated following in the UK and Northern Europe, particularly among enthusiasts of traditional rigs. The boat has been featured in several independent sailing logs and amateur film series, most notably the "Liverpool to Anglesey" voyage documented by John Turner, which showcases the boat’s ability to handle coastal passage-making in moderate conditions. It is also a frequent subject of discussion in British nautical periodicals like Practical Boat Owner, where it is praised for its "mini-tall ship" character.

Known Issues & Buyer’s Checklist

• Weather Helm & Keel Alignment: Potential buyers should verify the operation of the lifting keel. In some units, the keel was mounted slightly too far forward relative to the mast, leading to persistent weather helm. Inspect the pivot bolt and lifting cable for corrosion or "slop," which can cause the keel to vibrate or jam.
• Deck & Hatch Integrity: The original main companionway hatches were often made of timber or lightweight GRP and are prone to rot or storm damage. Many owners have replaced these with custom-fabricated sliding hatches to improve safety and waterproofing.
• Ballast Distribution: Early models were noted for being "light" and required significant crew weight in the cockpit to stay on their lines. Buyers should check if permanent lead or water ballast has been added under the cabin sole, a common aftermarket modification to improve stiffness.
• Chainplates and Rigging: On gaff-rigged versions, the tension on the bowsprit and the complexity of the running rigging put significant stress on the chainplates. Look for spiderweb cracking in the gelcoat around these attachment points, indicating structural fatigue.
• Outboard Well Maintenance: The Privateer 20 features an engine well for an outboard. These wells can become traps for exhaust fumes or sea spray; ensure the well is properly drained and that the surrounding GRP is not delaminated from the weight of modern, heavier four-stroke engines.

Community & Resources

The most active repository for technical data and owner support is the Privateer 20 Owners Group, a community that preserves original manufacturer literature and designer instructions. Technical discussions regarding rig tuning and keel repairs are also frequently archived on the YBW (Yachting British Weekly) Forums, a high-signal resource for UK-built vintage yachts.

The Verdict

The Privateer 20 is an aesthetically striking pocket cruiser that offers a "big boat" feel in a trailerable package. It is an ideal entry-point for sailors captivated by traditional gaff rigs and clipper-style aesthetics, provided they accept the limitations of its size.

Pros

• Striking traditional aesthetics with a classic clipper bow.
• Easily trailerable and capable of exploring shallow, shoal-draft waters.
• Versatile gaff cutter rig allows for easy sail management in varying winds.
• Active owner community provides a wealth of DIY technical knowledge.

Cons

• Significant weather helm if the keel and sail plan are not perfectly balanced.
• Cramped interior with only sitting headroom and minimal storage.
• Light displacement makes it less suitable for heavy weather or offshore use.
• The centerboard trunk significantly obstructs the living area.
