Grampian 28 Information, Review, Specs

Sailing Performance & Handling

Under sail, the Grampian 28 is characterized by its predictable, if somewhat conservative, motion. With a Displacement/Length (D/L) ratio typically hovering in the 340 range, it sits firmly in the heavy-displacement category for its size. This mass provides a significant amount of momentum, allowing the hull to punch through head seas that would stop lighter boats in their tracks. However, the trade-off is found in light-air performance; with a Sail Area/Displacement (SA/D) ratio of roughly 14.8, the boat requires a substantial headsail, such as a 150% genoa, to remain competitive in breezes under 10 knots.

The boat’s underwater profile features a swept-back fin keel and a skeg-hung rudder, a configuration praised in Canadian Yachting's technical review for providing excellent tracking and protection for the steering gear. Owners often report that the boat is exceptionally well-balanced, carrying a slight weather helm that provides communicative feedback through the tiller or the optional pedestal steering. While it is not a "pointing" machine and typically struggles to match the close-hauled angles of more modern performance cruisers, it excels on a reach, where its waterline length and beam provide a stiff, stable platform.

Interior Comfort & Variations

The interior of the Grampian 28 was a revelation at the time of its release, offering a level of "liveability" usually reserved for 30-footers. The cabin provides approximately 6 feet 2 inches of headroom, a significant upgrade over the Grampian 26. The layout is traditional but efficient: a V-berth forward, followed by an enclosed head to port and a hanging locker to starboard. The main salon usually features a dinette that converts into a double berth, with a settee opposite that doubles as a sea berth.

A notable variation in the production run involves the galley location and the engine access. Earlier models often featured the universal Atomic 4 gasoline engine, while later versions occasionally saw diesel repowers. The cabinetry is typically finished in teak veneers and solids, which, when maintained, give the boat a warm, traditional aesthetic. Because the hull was used consistently across the production run, there are no major structural variants like the 4-cabin versions found in larger European yachts; the Grampian 28 remained focused on the private owner rather than the charter market.

Known Issues & Buyer’s Checklist

Prospective buyers should approach a Grampian 28 with a focus on structural longevity, as these boats are now reaching five decades of age.

• Deck Delamination: Like many boats of this era, Grampian used a balsa-cored deck. Moisture ingress around stanchion bases, cleat mounts, and the mast step is common. Soft spots in the cockpit sole or side decks are high-signal indicators of core rot.
• Rudder Integrity: The skeg-hung rudder is robust, but the internal steel skeleton can corrode if water penetrates the fiberglass skin, leading to "rudder bloom" or delamination.
• Chainplates: The stainless steel chainplates are bolted through the bulkheads. Over time, leaks at the deck joint can rot the plywood bulkheads, compromising the structural integrity of the rig.
• Engine Serviceability: If the original Atomic 4 remains, check the manifold for cracks and the cooling passages for scale buildup. Many owners prefer the reliability of a newer Yanmar or Beta Diesel, which significantly increases the vessel's resale value.

Community & Resources

The Grampian 28 benefits from one of the most dedicated owner associations in North America. The Grampian Owners Marina serves as a vital technical repository, offering digitized copies of original manuals and crowd-sourced solutions for specific repair tasks. This community is particularly active in the Great Lakes region, where regional "Grampian Rendezvous" events are still occasionally held.

The Verdict

The Grampian 28 is a "stout" cruiser that prioritizes safety and comfort over raw speed. It remains an excellent entry-level yacht for those looking to explore coastal waters or the Great Lakes on a budget.

Pros:

• Exceptional interior headroom and volume for a 28-foot boat.
• Heavy displacement provides a sea-kindly motion in rough weather.
• Skeg-hung rudder offers superior protection and tracking.
• Robust construction and active owner community.

Cons:

• Luggish performance in light winds (under 10 knots).
• Potential for significant deck core issues if neglected.
• Original Atomic 4 engines require meticulous maintenance.
