The Hunter 28.5, produced between 1985 and 1988, represents a pivotal era for Hunter Marine as the company transitioned toward the high-volume, performance-oriented cruising market. Designed by naval architect Cortland Steck, the 28.5 was intended to offer a "big boat" feel within a footprint that remained manageable for a shorthanded crew or a young family. During its four-year production run, nearly 800 hulls were completed, making it one of the more successful mid-sized cruisers of the 1980s. It effectively replaced the earlier Cherubini-designed Hunter 27, offering a more modern hull shape with a wider beam carried well aft and a significantly more sophisticated interior.

Sailing Performance & Handling

The Hunter 28.5 is frequently characterized by its surprising stiffness and agility, a result of its high ballast-to-displacement ratio of approximately 43%. Unlike many modern "light air" cruisers that rely on extreme beam for stability, the 28.5 uses a substantial lead keel—offered in both a 4’ 0” shoal draft and a 5’ 2” deep draft configuration—to maintain a low center of gravity. This makes the vessel remarkably capable in a breeze, though its relatively light displacement of 7,000 lbs allows it to accelerate quickly in light-to-moderate conditions.

According to technical specifications archived by Marlow-Hunter, the boat features a high-aspect rig with a large mainsail and a relatively small foretriangle. This sail plan makes the boat easy to tack and balance, though it requires early reefing; most owners find the boat performs best when kept upright, as excessive heel can lead to weather helm. The T-shaped cockpit is ergonomically designed for sail handling, with primary winches positioned within reach of the helm, facilitating single-handed operation. While not a dedicated racer, the 28.5 maintains a respectable PHRF rating (typically around 180), allowing it to remain competitive in casual club racing.

Interior Comfort & Variations

For a vessel under 30 feet, the Hunter 28.5’s interior was considered revolutionary at its launch. Cortland Steck utilized the 10' 6" beam to create an open, airy salon with a headroom of roughly 6' 2". The layout follows a standard but refined path: a V-berth forward, a central salon with opposing settees, and a functional galley to starboard. High-authority editorial reviews, such as those from Practical Sailor, note that the use of a "wraparound" settee and the omission of a full bulkhead between the salon and V-berth enhances the sense of space, though it sacrifices some privacy.

The 28.5 was one of the first boats in this size range to offer a dedicated aft cabin, which features a double berth tucked under the cockpit sole. While the overhead clearance in this berth is tight, it provides a permanent sleeping area that does not require converting the salon table. The galley is equipped with a two-burner stove and a deep icebox, reflecting its purpose as a coastal weekender. Throughout its production, the interior aesthetic remained consistent, utilizing teak veneers and molded fiberglass liners for a balance of traditional warmth and modern ease of maintenance.

While the Hunter 28.5 does not have a single "hero voyage" recorded in maritime literature, it is widely cited in sailing media as a benchmark for the "performance cruiser" category of the 1980s. It appeared frequently in period-specific technical comparisons in Sail Magazine and Yachting, often praised for its value-to-performance ratio. Its cultural footprint is most visible today in the secondary market, where it remains a frequently recommended "first boat" for coastal sailors transitioning from dinghies to keelboats.

Known Issues & Buyer’s Checklist

Prospective buyers should approach the Hunter 28.5 with an eye toward the structural realities of 1980s production boatbuilding. Synthesizing data from owner technical exchanges and marine surveyors, several specific areas require scrutiny:

  • Compression Post Support: A common "gotcha" on this model is the deterioration of the wooden block located beneath the cabin sole, which supports the compression post. If this block rots due to bilge water, the deck can sag at the mast step, leading to rig tension issues and interior door misalignment.
  • The "Hunter Smile": Like many boats of this era with external lead keels, the 28.5 can develop a hairline crack at the leading edge of the keel-to-hull joint. While often cosmetic, it should be inspected to ensure the keel bolts are torqued to factory specifications.
  • Portlight Leaks: The original plastic framed portlights are prone to UV degradation and leaking. Many owners replace these with upgraded stainless steel or aluminum units to prevent moisture damage to the teak interior.
  • Deck Coring: Standard moisture testing is essential around the chainplates and stanchion bases. If hardware was not re-bedded periodically, the balsa core in these areas may have suffered delamination.

Community & Resources

The Hunter 28.5 benefits from one of the most robust owner networks in North America. The Hunter Owners Association (specifically the technical archives at HunterOwners.com) provides a massive repository of owner-contributed modifications, parts lists, and structural repair guides tailored specifically to this hull. Because Marlow-Hunter still supports many of its legacy models, original parts and technical drawings are often available through their customer service portal, providing a level of longevity rarely seen in discontinued 28-foot models.

The Verdict

The Hunter 28.5 is an exceptionally balanced coastal cruiser that offers more "living room" and sailing performance than its price point typically suggests. While it requires the diligence of a seasoned owner to manage 1980s-era maintenance, it remains a stiff, fast, and remarkably comfortable vessel.

Pros

  • Performance: High ballast-to-displacement ratio ensures a stiff, stable ride in coastal chop.
  • Interior Volume: 6' 2" headroom and an aft cabin are rare and welcome features for a 28-foot boat.
  • Ease of Use: Simple rig design and T-shaped cockpit make it an ideal platform for single-handers.

Cons

  • Structural Aging: Common issues with the compression post and deck core require careful pre-purchase inspection.
  • Engine Access: While the Yanmar diesel is reliable, the engine compartment can be cramped for major repairs.
  • Draft Sensitivity: The deep-draft version is significantly more weatherly but may limit access to some thin-water cruising grounds.
