1983–1987 · designed by Cortland Steck · built by Hunter Marine
The Hunter 31 was designed by Cortland Steck as an affordable performance-cruiser for the US market, prioritizing interior volume and ease of sailing over offshore capability. Built to a price point for the 1983–1987 production run, it offered coastal cruisers and weekenders a spacious, beamy hull with relatively light displacement. The class developed a reputation as a comfortable daysailer and coastal boat but is not regarded as a serious bluewater passage-maker.
This is a general read on the Hunter 31 class — informed
background, not a verdict on any individual boat. Condition, refit history,
and how a particular hull was sailed and stored matter far more than class
reputation. Use it to know what to look for; for a read on a specific

What the Hunter 31 is known for
Above-average interior volume and headroom for a 31-foot production boat, making the cabin genuinely livable for weekend use.
Simple fin-keel/spade-rudder layout sails well short-handed and the rig is easy to manage solo.
Hunter bonded a full-length internal frame and stringer system of unidirectional fibreglass directly to the hull. It is a better structural approach than the price point suggests, and it is why well-kept hulls hold up despite the class's reputation.
Large Hunter production run means parts, used sails, and class knowledge are widely available in the US used-boat market.
Resale values are modest, meaning a well-maintained example represents reasonable value for a first cruising boat on a tight budget.
Known trade-offs
Production-grade laminate and balsa coring throughout make deck moisture intrusion a near-universal finding on unrestored hulls.
Deck-stepped rig concentrates compression loads on the cabin top structure, which ages poorly when water intrusion is present.
Cast-iron fin keel. Rust forms along the joint where the iron meets the fibreglass — the factory gelcoat over that joint wears away, the crack opens, and a rust line appears. Unrestored examples frequently show weeping keel bolts and internal corrosion that is easy to underestimate on a cursory inspection.
Light displacement and moderate ballast ratio limit ultimate stability and seakeeping in rough offshore conditions.
Many examples carry deferred maintenance from budget-conscious owners; the low purchase price often masks a significant refit cost to bring the boat to a reliable standard.
Owners quoted in the marine press are candid that she was not built with the notion that she would still be sailing far into the next century, and single out substandard winches and the joinery below. Buy her for what she is — a roomy, easily-handled coastal boat at a low entry price — not for longevity.

Systems to check before you buy
Deck core and chainplate kneespriority: offshore, coastal, liveaboard
Balsa or plywood deck core common on this era of Hunter. Chainplate penetrations and stanchion bases are the primary water-entry points. Probe and moisture-meter the entire side deck and chainplate area; soft spots are common and repair can escalate quickly if structural knees are involved.
Standing rigging and mast steppriority: offshore, coastal, racing
Deck-stepped rig means compression loads transfer through the cabin top. Inspect the compression post below for softness or separation. Rigging wire on unrestored hulls is likely original or near end-of-life; budget a full replacement unless documented recently.
Keel-to-hull joint and cast-iron keel conditionpriority: offshore, coastal, liveaboard
Bolt-on cast-iron fin keel; inspect the keel sump and bilge for rust weeping, keel bolt corrosion, and any cracking in the hull laminate at the stub. Cast iron rusts from within, so surface rust on the keel alone understates the risk. Keel bolt replacement on a badly weeping keel is a significant haulout job.
Engine and raw-water cooling systempriority: coastal, liveaboard, motor
All production Hunter 31s were fitted with Yanmar diesel engines (13 hp early, 16 hp later). These are well-regarded but now 40-year-old installations. Check raw-water impeller service history, heat exchanger condition, and exhaust elbow — elbows corrode from the inside out on aged installations. Budget a repower if the engine shows signs of neglect or has no service history.
Hull blister and laminate conditionpriority: offshore, coastal, liveaboard, weekending
Early hulls (1983–1985) are candidates for osmotic blistering. Haulout inspection under the waterline is essential; active blistering with liquid-filled voids indicates ongoing laminate moisture ingress. Barrier coat application after full blister repair is the standard remediation.
How it fits your plans
Offshore
Not recommended for offshore passagemaking. Light displacement, deck-stepped rig, and production-grade laminate make this a coastal boat that should not be pressed into bluewater service without significant upgrades most buyers won't find worthwhile.
Coastal
A reasonable coastal cruiser for sheltered and semi-exposed waters. Spacious for its length, easy to sail short-handed, and parts support exists. Keep it in its intended environment and it performs well.
Liveaboard
Interior volume is above average for a 31-footer, making it a viable liveaboard in a protected marina berth. Expect to invest in systems upgrades (electrical, water, refrigeration) that will stress an aging hull.
Weekending
This is the class's sweet spot — weekend sailing in protected or semi-protected waters with a comfortable, sociable interior for 2-4 people.
Racing
Not a competitive racer by modern standards; PHRF handicap sailing only, and performance will depend heavily on bottom paint condition and rig tune.
