Harstad 31 Information, Review, Specs

Sailing Performance & Handling

The Harstad 31 is defined by its heavy-displacement profile and a hull shape that prioritizes tracking over agility. With a displacement of approximately 8,000 pounds and a narrow 8-foot beam, the boat has a relatively high displacement-to-length ratio compared to its lighter sibling, the Clipper Marine 32. This mass, combined with a full-length keel and a transom-hung rudder, results in exceptional directional stability; the boat is noted for its ability to hold a course with minimal helm correction, a hallmark of Crealock’s "sea-kindly" design philosophy.

Rigged as a masthead ketch, the Harstad 31 offers a versatile sail plan that is easily managed by a solo sailor or a couple. The ketch configuration allows for numerous sail combinations, such as the "jib and jigger" (headsail and mizzen) setup, which is ideal for maintaining stability in heavy weather or while motoring. However, the narrow beam and relatively low ballast ratio (roughly 24%) mean the boat can be somewhat tender initially, though it gains stability as the deep hull settles into its lines. Owners frequently report that while the boat is not a "pointing machine" upwind, its performance on a reach is steady and predictable. Under power, most models are equipped with a 20-hp Yanmar diesel, which is sufficient for hull speed in calm conditions but may feel underpowered when battling significant headseas.

Interior Comfort & Variations

One of the most surprising features of the Harstad 31 is its vertical volume. Despite its narrow beam, the design incorporates a prominent doghouse or pilothouse that provides exceptional headroom, reaching over 7 feet in the main cabin areas according to owner accounts on SailNet. This architectural choice transforms what would otherwise be a cramped "needle-hull" into a light, airy living space. The interior layout typically features a large V-berth forward, a central head, and a galley located under the doghouse to take advantage of the standing room.

The use of a pilothouse also provides a protected interior steering station or at least a sheltered "observation deck" for the crew, a rare luxury in a boat of this size. Materials used in the mid-70s production runs were utilitarian, focusing on fiberglass liners and teak accents. Because the Harstad 31 was essentially a refined, heavier version of the Clipper Marine 32, it shares some aesthetic DNA with that model, but the Harstad's build quality is significantly higher, featuring thicker laminates and more robust hardware.

Known Issues & Buyer’s Checklist

Due to the extremely low production numbers, finding a Harstad 31 is difficult, and those that appear on the market often require specialized inspection.

• Deck Core Integrity: Like many fiberglass boats from the 1970s, the Harstad 31 used a balsa-cored deck. Buyers should check for soft spots around the chainplates and the base of the doghouse, where water penetration over five decades can cause significant rot.
• Fuel and Water Tankage: Original specifications included relatively small tanks (approximately 25 gallons of fuel and 45 gallons of water). For serious cruising, many owners have had to retrofit additional capacity or inspect original aluminum tanks for pitting and corrosion.
• Ballast and Keel Sealing: While the full keel is robust, the interface where the ballast is encapsulated or attached should be checked for "smiles" or signs of movement, especially if the boat has been frequently trailered.
• Engine Accessibility: While the doghouse provides headroom, the engine compartment tucked beneath the cockpit can be difficult to access for routine maintenance. Prospective buyers should inspect the condition of the 2QM20 Yanmar (if original) for signs of cooling system scaling common in older raw-water-cooled units.

Community & Resources

Due to its rarity, there is no formal "Harstad Owners Association." However, because the design is so closely linked to the Clipper Marine 32, owners often find technical support and hardware compatibility advice through the Clipper Marine Owners groups and forums like SailNet, where former Harstad owners have documented their refits. Technical data on the designer’s broader philosophy can also be found through the archives of the Crealock Design legacy, often referenced in historical nautical publications.

The Verdict

The Harstad 31 is a quirky, robust, and highly capable small cruiser that defies modern trends by remaining trailer-legal without sacrificing the "big boat" feel of a pilothouse. It is best suited for the sailor who values stability and headroom over raw speed and cockpit space.

Pros

• Exceptional Headroom: Rare 7ft+ clearance in a 31-foot hull.
• Trailerability: The 8-foot beam allows for transport without wide-load permits.
• Sea-Kindliness: Excellent tracking and heavy-weather stability thanks to the Crealock hull and ketch rig.
• Exclusivity: A conversation-starting classic with very few sister ships in existence.

Cons

• Narrow Beam: Can feel tender initially and has a smaller cockpit than modern 31-footers.
• Rarity: Sourcing specific replacement parts for the doghouse or unique trim can be challenging.
• Maneuverability: The long keel makes backing in tight marinas difficult for the uninitiated.
