Hinterhoeller HR-28 Information, Review, Specs

Sailing Performance & Handling

The HR-28 is characterized by a high ballast-to-displacement ratio (approximately 42%), which provides a level of stability often missing in contemporary 28-footers. With a displacement of roughly 6,500 pounds and 2,750 pounds of lead ballast, the boat is remarkably stiff, standing up well to its canvas as the wind freshens. Its underwater profile features a swept-back fin keel and a spade rudder, a configuration that George Hinterhoeller favored for its balance of tracking and maneuverability.

Under sail, the HR-28 feels deliberate and balanced. The masthead sloop rig is conservatively stayed, providing a reliable platform for offshore coastal hops. According to historical technical reviews often cited by the Niagara Owners Association, the boat avoids the "skittish" feel of lighter-displacement racer-cruisers, maintaining its momentum through a chop. While it lacks the raw acceleration of a Shark 24, its motion is more comfortable for long-distance cruising. The Sail Area to Displacement (SA/D) ratio of approximately 15.5 indicates a moderate power plan—it requires a headsail of at least 135% to perform optimally in light air, but it truly shines in the 12-to-18 knot range.

Interior Comfort & Variations

The interior of the HR-28 reflects George Hinterhoeller’s European apprenticeship, featuring high-quality joinery and a layout that maximizes every inch of its 9' 2" beam. The traditional arrangement includes a V-berth forward with an overhead hatch for ventilation, followed by a full-width head compartment. In the main salon, two settee berths flank a central folding table, with a compact galley to port and a dedicated navigation station and quarter berth to starboard.

A defining characteristic of this model is the extensive use of teak and the quality of the fiberglass moldings. The HR-28 was built alongside the HR-25, its smaller sibling, but offered significantly more "elbow room" and standing headroom (roughly 6' 1"), making it a viable long-term cruiser for a couple. While the HR-28 remained largely consistent in its layout, minor variations exist in the galley configuration depending on whether the original owner opted for a gimbaled stove or a simpler two-burner setup. The hull’s solid laminate and balsa-cored deck provide a quiet, insulated cabin environment that remains dry even in heavy weather.

Known Issues & Buyer’s Checklist

Prospective buyers of the HR-28 should prioritize a thorough inspection of the deck and structural components, as these boats are now approaching their fifth decade of service.

• Deck Core Saturation: Like many boats of this era, the HR-28 uses a balsa-cored deck. Moisture ingress around the chainplates, stanchion bases, and the mast step is common. Soft spots or elevated moisture readings in these areas are high-signal indicators of needed core replacement.
• Chainplate Leaks: The chainplates on the HR-28 pass through the deck to the bulkheads. If the sealant is not regularly maintained, water can migrate into the plywood bulkheads, leading to rot. Inspect the wood where the chainplates bolt through for staining or softness.
• Original Engine Condition: Many HR-28s were originally fitted with the Universal Atomic 4 (gasoline) or the early Universal 5411 diesel. While the Atomic 4 is reliable if maintained, many cruisers prefer the safety and efficiency of a modern diesel. Check the exhaust riser and cooling passages for scale buildup.
• Rudder Post and Bearing Wear: The spade rudder is a robust unit, but the bearings can develop play over time. A "clunk" felt through the tiller or wheel while underway usually indicates that the bushings require replacement.

Community & Resources

The HR-28 benefits from a highly active and technically proficient community. Because it shares construction techniques and philosophies with the larger Niagara and Nonsuch lines, owners often find support through the Nonsuch Owners Association and the various Niagara technical wikis. These groups maintain archives of original Hinterhoeller blueprints and parts lists that are invaluable for restoration projects.

The Verdict

The Hinterhoeller HR-28 is a "sailor’s sailboat," designed for those who value craftsmanship and sea-kindliness over modern "condo-maran" volume. It is an ideal vessel for a couple or small family looking to cruise the Great Lakes or coastal waters in a boat that feels significantly more substantial than its length suggests.

Pros:

• Exceptional Build Quality: Superior fiberglass work and teak joinery compared to mass-market contemporaries.
• Stiff and Stable: A high ballast ratio ensures a safe, upright sailing experience in heavy weather.
• Timeless Aesthetics: Classic lines that avoid the dated look of many 1970s designs.

Cons:

• Small Cockpit: The cockpit is prioritized for safety and sailing efficiency rather than dockside entertaining.
• Aged Systems: Original plumbing and wiring will likely require updates to meet modern standards.
• Deck Maintenance: Balsa-core decks require vigilance to prevent costly saturation issues.
