Hunter 31 Information, Review, Specs

Sailing Performance & Handling

The Hunter 31 is characterized by a fractional B&R rig, a design choice that allows for a larger mainsail and smaller, more manageable headsails. This configuration, combined with a displacement-to-length (D/L) ratio of approximately 240, places the boat firmly in the "medium displacement" category. It is a capable coastal performer that feels surprisingly light on the helm. Owners frequently report that the boat excels in light-to-moderate air, thanks to a relatively high Sail Area-to-Displacement (SA/D) ratio for a cruiser of its vintage, which keeps the hull moving when heavier traditional cruisers might stall.

Under sail, the 31 exhibits a fair amount of initial heel due to its significant beam, but it stiffens up considerably once the hull finds its "sweet spot" at roughly 15 degrees. The boat’s tracking is aided by a balanced spade rudder, though the large mainsail requires early reefing—typically around 15 to 18 knots of true wind—to maintain control and prevent excessive weather helm. While not a bluewater yacht by modern standards, its 41% ballast-to-displacement ratio provides a level of stability and sea-kindliness that makes it a trusted platform for crossing the Great Lakes or navigating the Chesapeake Bay.

Interior Comfort & Variations

At the time of its release, the Hunter 31’s interior was considered revolutionary for its size. By pushing the beam to nearly 11 feet, the design team created a salon that feels significantly larger than contemporary rivals like the Catalina 30. The layout features a traditional V-berth forward, but the standout feature is the "athwartships" double berth located tucked under the cockpit sole. This aft sleeping area, while tight on headroom, provided a level of privacy rarely seen in 31-footers of the early 1980s.

The galley is L-shaped and positioned to starboard, equipped with a two-burner stove and a deep icebox. High-authority editorial reviews from the era noted the use of teak veneers and solid teak trim, which provided a warmer, more traditional aesthetic than the "all-white" fiberglass interiors of cheaper competitors. Variations of this hull were largely limited to the keel depth, though the Hunter 31’s success directly informed the development of its larger sibling, the Hunter 34, which shared nearly identical design DNA and construction methods. For buyers looking for more modern iterations, the "Hunter 310" and the later "Hunter 31-2" (released in the 2000s) are entirely different hulls and should not be confused with this 1980s classic.

Known Issues & Buyer’s Checklist

Prospective buyers should approach a vintage Hunter 31 with a focus on structural maintenance common to production boats of this age.

1. Compression Post Decay: A high-signal issue for this model is the deterioration of the wooden block located at the base of the compression post beneath the cabin sole. If the bilge has been kept wet, this block can rot, causing the deck to sag slightly at the mast step.
2. Deck Delamination: Like many boats from the 80s, the Hunter 31 uses a balsa-cored deck. Rigorous moisture testing around the chainplates, stanchion bases, and the T-shaped cockpit is essential, as hardware bedding often fails over four decades.
3. Rudder Integrity: The foam-filled spade rudder is prone to "wicking" water if the fiberglass skin is breached. Buyers should check for "weeping" or rust-colored stains at the bottom of the rudder when the boat is hauled.
4. Engine Maintenance: Most units were powered by the Yanmar 2GM20F. While these are "bulletproof" engines, the mixing elbow is a known failure point that can lead to carbon buildup or engine flooding if not replaced every few years.

Community & Resources

The Hunter 31 benefits from one of the most robust owner networks in the marine industry. The Hunter Owners Association (often found via the Marlow-Hunter archives) provides an exhaustive repository of original manuals, wiring diagrams, and parts lists. Because so many of these vessels were built, technical support for specific upgrades—such as replacing the original gate valves with modern seacocks—is readily available through these dedicated technical wikis.

The Verdict

The Hunter 31 remains an excellent entry-level cruiser for sailors who prioritize interior volume and ease of handling over heavy-weather ruggedness. It is a "honest" boat that delivers exactly what it promises: comfortable coastal cruising at an accessible price point.

Pros:

• Exceptional interior volume for a 31-foot vessel.
• Reliable Yanmar diesel powerplants are standard on most hulls.
• Nimble light-air performance due to the B&R fractional rig.
• Active owner community makes parts and advice easy to source.

Cons:

• Requires early reefing to manage weather helm in heavy air.
• Original deck hardware and ports are prone to leaks if not re-bedded.
• The "T-shaped" cockpit can feel cramped with more than four adults.
