The Marlow-Hunter 31, introduced in 2014, represents a significant evolution in the mid-size cruising market, blending the accessibility of the legacy Hunter brand with the refined construction standards introduced by David Marlow. Designed by Glenn Henderson, this model was engineered to feel and perform like a much larger vessel, utilizing a hull form that emphasizes volume without sacrificing the sailing characteristics Henderson is known for. Unlike its predecessor from the 1980s, the Marlow-Hunter 31 features a distinctive hard chine carried well aft, a wide beam of 11 feet 10 inches, and a sleek profile that reflects modern European design influences. It serves as a pivotal "entry-level" cruiser for families, offering a sophisticated balance of stability and interior luxury that was once reserved for yachts in the 35-to-40-foot range.

Sailing Performance & Handling

Under sail, the Marlow-Hunter 31 benefits significantly from Glenn Henderson’s "Grid" construction and a hull design that incorporates a slight hollow in the bow to improve entry, coupled with a hard chine that provides a powerful righting moment. As noted in a detailed review by Sail Magazine, the boat exhibits impressive stability when pressed, with the chine acting as a longitudinal "rail" that helps the boat track straight even in gusty coastal conditions. The sail plan is built around the signature B&R rig—a tripod-style arrangement with swept-back spreaders and no backstay. This configuration allows for a high-aspect mainsail with a large roach, providing the primary driving force for the vessel.

With a displacement-to-length ratio that leans toward the moderate-cruiser end of the spectrum, the MH31 is not a light-air racer, but it is remarkably nimble in a breeze. The absence of a backstay allows for an easy-to-handle fractional rig where the mainsail can be shaped aggressively. Handling is further simplified by the lead-at-cockpit lines and a high-clearance stainless steel cockpit arch, which keeps the mainsheet traveler out of the way of the crew. Owners often remark on the boat's ability to maintain a comfortable heel angle, a direct result of the wide beam and low center of gravity afforded by the optional deep keel or the standard wing keel.

Interior Comfort & Variations

The interior of the Marlow-Hunter 31 is where the "Marlow" influence is most palpable, moving away from the more utilitarian finishes of earlier Hunter models toward richer hardwoods and more robust joinery. The layout is optimized for four to six people, featuring a surprisingly large master aft cabin that spans the width of the beam. This cabin provides a level of headroom and horizontal space rarely seen in 31-foot hulls, often a deciding factor for buyers comparing it to older 33-foot models. The forward V-berth is adequate for guests or children, while the salon features a drop-leaf table that integrates seamlessly with the settees.

The galley is positioned to starboard and is equipped with a stainless steel sink, a two-burner stove, and sufficient refrigeration for weekend or week-long coastal hops. One of the technical variations available for this model includes the choice between a standard slab-reefing mainsail or an in-mast furling system; while the latter sacrifices some sail area and performance due to the lack of horizontal battens, it is the more popular choice for shorthanded couples. The MH31 shares design DNA and structural components with its larger sibling, the Marlow-Hunter 33, utilizing the same HKT (Hunter Kevlar Technology) in the forward section of the hull to provide impact resistance.

The Marlow-Hunter 31 gained immediate industry recognition upon its release, being named a "Best Boats" winner by Sail Magazine in 2015. The judges specifically highlighted its innovative use of space and the quality of the "Marlow" upgrades to the interior. It has also been featured in technical walkthroughs by Cruising World, which praised the vessel's accessibility for new sailors. While it has not been the subject of high-profile circumnavigations like the larger Hunter 50 or the record-breaking Thursday’s Child, it has become a staple of modern "how-to-sail" media and charter fleets focused on coastal education.

Known Issues & Buyer’s Checklist

Prospective buyers of a pre-owned Marlow-Hunter 31 should focus their inspection on several specific areas common to the B&R rig and the Marlow-era construction:

  • B&R Rig Tension: Because the rig lacks a backstay, the tension on the swept-back shrouds is critical for mast stability. Buyers should ensure the standing rigging has been professionally tuned to prevent mast "pumping" in heavy seas.
  • Swim Platform Hinges: The fold-down transom is a hallmark of this model, but the manual cables and hinge points are subject to high stress and saltwater corrosion. Check for smooth operation and any hairline fractures around the mounting points.
  • Sail-Drive Seal: Most MH31s are powered by a Yanmar diesel engine with a sail-drive unit. It is vital to verify the age of the rubber bellows seal; manufacturers typically recommend replacement every seven to ten years.
  • Deck Hardware Bedding: While Marlow improved the overall build quality, checking the bedding of the cockpit arch is essential. Any signs of moisture ingress around the arch bases can lead to core issues over time if not addressed.

Community & Resources

Owners of the Marlow-Hunter 31 benefit from one of the most robust support networks in the sailing world. The Marlow-Hunter Owners Association serves as a central hub for technical documentation, including original wiring diagrams and plumbing schematics. Additionally, the Hunter Sailing community is active on various technical wikis where Henderson-specific design questions regarding the hard chine and HKT hull reinforcement are frequently discussed.

The Verdict

The Marlow-Hunter 31 is a quintessential modern coastal cruiser that punches well above its weight class in terms of interior volume and stability. It is an ideal vessel for sailors transitioning from daysailers to overnight cruising or for those downsizing from larger, more maintenance-intensive yachts.

Pros:

  • Exceptional interior volume and headroom for a 31-foot boat.
  • The hard-chine hull provides excellent stability and predictable handling.
  • Cockpit arch keeps the mainsheet traveler clear of the crew, enhancing safety.
  • High-quality Marlow-era interior finish compared to older Hunter models.

Cons:

  • The B&R rig configuration can make downwind sailing more challenging due to the inability to square back the mainsail fully.
  • Moderate sail-area-to-displacement ratio means it may struggle in very light air without a Code 0 or asymmetrical spinnaker.
  • Limited storage for long-term blue-water cruising, as it is primarily designed for coastal use.
