Design Brief & Intent
The Grampian 28 was conceived to bridge the gap between nimble club racers and comfortable family cruisers. Standing out from its predecessor, the Grampian 26, the 28-footer offered a dramatic increase in interior volume and structural stiffness, thanks to its generous 9-foot, 6-inch beam and a heavy-ballast layout. The higher freeboard and straight, plumb stem gave the boat a modern, "big boat" profile, maximizing both waterline length and interior headroom to an impressive 6 feet, 2 inches.
Below deck, the layout is highly traditional but exceptionally well-utilized. It features a classic V-berth forward, followed by an enclosed head to port and a hanging locker to starboard. The main salon incorporates a convertible dinette and a settee, with the notable inclusion of a starboard quarter berth that was considered a luxury for a vessel of this length in the mid-1970s. The joinery leans on rich teak or mahogany trim, providing a warm, robust feel that reflects the era's high standard of Canadian craftsmanship.
Variations & Configurations
Throughout its production run, the Grampian 28 was configured to satisfy both regional draft limitations and varying owner preferences.
- Keel Profiles: The standard configuration featured a fixed fin keel with a draft of 4 feet, 10 inches, maximizing lift and pointing ability. For thin-water cruising grounds, such as the Chesapeake Bay or portions of the Great Lakes, Grampian offered an optional shoal draft keel drawing just 3 feet, 9 inches.
- Auxiliary Propulsion: Though some hulls were initially equipped with the venerable, gasoline-powered Universal Atomic 4, many came straight from the factory with a Swedish-built Volvo Penta MD7A diesel. This engine was paired either with a standard shaft drive or, more commonly, a Volvo Penta 110S saildrive unit, which minimized vibration and freed up additional cabin space aft.
Sailing Performance & Handling
On the water, the Grampian 28 displays the predictable, stiff, and forgiving motion of a classic cruiser-racer. Its impressive ballast-to-displacement ratio of 44.35% makes the boat exceptionally stiff, allowing it to stand up to its canvas and carry a high degree of stability even when caught in sudden gusts. With a moderate displacement-to-length ratio of 209.46, the hull has enough momentum to punch through steep, confused head chop without losing steerage, a trait highly valued by Great Lakes and coastal sailors.
The sail-area-to-displacement ratio of 16.95 indicates a well-balanced masthead sloop rig. While it requires a large overlapping headsail (such as a 135% or 150% genoa) to remain lively in light air under 10 knots, the boat comes alive on a reach. Helming is highly communicative; the underwater profile, featuring a swept-back fin keel and a solid skeg-mounted rudder, tracks beautifully on all points of sail while protecting the steering gear from impact. A capsize screening ratio of 2.0 indicates it sits right on the boundary line for offshore work, meaning it is ideally and safely classified as a robust coastal cruiser.
Known Issues & Triage
For prospective buyers and current owners, a few age-related structural areas require careful inspection.
- Bulkheads & Chainplates: The stainless steel chainplates are through-bolted to the structural plywood bulkheads. If the deck chainplate seals are neglected, water tracks down into the bulkheads, causing rot that compromises the rig's structural integrity. This requires re-bedding the chainplates and, in severe cases, replacing or sistering the wooden bulkheads.
- Deck Core Rot: Like many production boats of the 1970s, the Grampian 28 utilizes a balsa-cored deck. Soft spots around high-load hardware, such as stanchion bases, the mast step, and cleat fittings, must be checked with a moisture meter and sounded with a mallet. Triage involves drilling out the soft areas, scraping back decayed balsa, and filling with epoxy resin or replacing the core.
- Saildrive Boot Maintenance: On diesel models equipped with the Volvo Penta saildrive, the rubber hull-diaphragm (the boot) has a manufacturer-recommended lifespan that is often ignored by owners. Any sign of cracking, leaking, or history of non-replacement calls for immediate haul-out and replacement to prevent catastrophic water ingress.
The Verdict
The Grampian 28 stands out as a highly successful evolution of a classic Canadian cruising lineage. By modernizing the hull profile and maximizing interior volume, Rolf van der Sleen created a vessel that feels like a 30-footer below deck while maintaining the nimble, easily managed handling of a 28-foot pocket cruiser. While its age means buyers must be diligent regarding deck cores and bulkhead rot, its heavy ballast ratio, skeg-hung rudder, and stiff sailing characteristics make it a premier choice for budget-conscious sailors seeking a sturdy, capable coastal cruiser.
Pros
- Exceptional interior volume and 6-foot, 2-inch headroom for a 28-foot boat.
- High stiffness and stability on the water, courtesy of a 44.35% ballast ratio.
- Skeg-hung rudder offers excellent tracking and steering gear protection.
- Pleasing, contemporary aesthetic that eschews the dated spoon bows of earlier eras.
Cons
- Original Volvo saildrive units require meticulous boot maintenance and can be difficult to source parts for today.
- Prone to deck soft spots and bulkhead rot if deck joints and chainplate seals are left unmaintained.
- Mediocre light-air performance without a large, high-maintenance overlapping genoa.
