Design Brief & Intent
The Maxfli 28 was conceived to bridge the gap between uncompromising IOR race boats and conservative, slow-moving cruising yachts. Julian Everitt sought a design that could perform admirably in weekend club races without requiring a large, highly trained crew or subjecting the family to Spartan accommodations. Compared to dominant models of the era, such as the Scandinavian Pelle Petterson-designed Maxi Fenix 8.5 or the English Sadler 29, the Maxfli 28 emphasized a slightly broader, more voluminous hull shape. Its beam of nearly ten feet gave it a structural presence that felt much larger than its twenty-eight feet of length would suggest. Below decks, Gilmax finished the interior with classic teak joinery and a traditional layout, creating a warm and comfortable cruising cabin. This robust, wood-trimmed accommodation package appealed directly to the cruising couple or young family who valued comfortable interior volume and the secure, heavy-duty feel of British fiberglass craftsmanship over stripped-out, lightweight racers.
Sailing Performance & Handling
At the helm, the Maxfli 28 displays a reassuringly stiff and stable character. The high ballast-to-displacement ratio of 42% indicates a boat with tremendous resistance to heeling, allowing it to stand up to its sail plan long after lighter cruiser-racers have begun to round up or require aggressive reefing. This inherent stiffness is further complemented by a displacement-to-length ratio of 274.35, placing the yacht firmly in the moderate-to-heavy cruising camp. This translates to a predictable, comfortable motion when carving through chop, rather than the rapid, jerky accelerations of lighter sportboats.
The sail plan, carrying a sail-area-to-displacement ratio of 14.56, suggests a conservative mainsail area that can feel slightly under-canvased in light summer breezes. However, like most masthead sloops of the late seventies, the Maxfli 28 is designed to generate its real horsepower from its headsails. Carrying a large overlapping genoa raises the effective sail area ratio closer to 17.5, giving the hull the driving power it needs in lighter airs. With a capsize screening ratio of 2.03, the boat features a wide beam that contributes to its impressive initial stability and interior room, though it places the design just outside the rigid boundary typically accepted for extreme, deep-ocean racing. A comfort ratio of 21.56 completes the performance picture, guaranteeing a soft, fatigue-reducing motion on the water that makes long coastal passages comfortable.
Configurations & Accommodations
Throughout its brief four-year production run, the Maxfli 28 was constructed primarily in a single, highly cohesive configuration: a masthead sloop rig paired with a high-aspect fin keel and a spade rudder. This combination was chosen to optimize both windward performance and marina maneuverability. The fin keel, drawing a modest four and three-quarter feet, allowed the boat to access shallow coastal creeks and estuaries while still providing excellent lift when beating into the wind. The spade rudder offered a crisp, responsive feel at the tiller, making the boat highly agile in tight quarters, though requiring a touch more active helming on long downwind runs compared to full-keeled cruisers.
The layout below decks maximizes the yacht’s generous 9.7-foot beam. Upon stepping down the companionway, the layout is remarkably traditional, featuring a compact galley to one side and a navigation station to the other. Two longitudinal settees in the saloon double as comfortable berths, flanking a central dining table. Forward, a solid bulkhead separates the main cabin from a dedicated head compartment, which in turn leads to a classic V-berth in the bow. A single quarter-berth tucked aft under the cockpit provides additional sleeping space or excellent storage for sails and cruising gear.
Market Snapshot & Economics
With roughly 26 hulls built by Gilmax Ltd., finding a Maxfli 28 on the brokerage market today requires patience. They are exceptionally rare, especially outside of the United Kingdom and Northern Europe. Consequently, they do not command the premium prices of more ubiquitous marques like Westerly or Sadler, trading instead as an insider’s secret that represents immense value for money. For the buyer who values robust construction over brand name recognition, the Maxfli 28 is an exceptionally economical entry point into classic yacht ownership.
However, prospective owners must carefully weigh the economics of vintage boat ownership. Refitting a vessel of this vintage often involves a financial commitment that can exceed its market value. Common projects include repowering the original diesel engine, updating aging DC electrical systems, replacing standing rigging, and upgrading basic electronics. Because of this, the Maxfli 28 is best suited for hands-on, DIY-capable sailors who can undertake modernization projects themselves, turning a rare, well-built classic into a highly capable, individualized pocket cruiser.
Known Issues & Modernization
As with any fiberglass production sailboat from the late 1970s, the Maxfli 28 has aged in ways that require targeted maintenance. The most critical area for potential owners to inspect is the balsa-cored deck. Over decades, neglected deck hardware, stanchions, and chainplates can allow water to seep into the core, leading to delamination and soft spots. Triage of these areas involves drilling out the soft core, potting the penetrations with epoxy, or replacing sections of rotten balsa with modern synthetic coring materials.
The cast-iron fin keel also requires routine vigilance. If the protective epoxy barrier coat is breached, rust blooming can occur. Veteran owners suggest sandblasting the keel to bare metal, applying a modern multi-coat epoxy primer system, and refairing the keel-to-hull joint. In terms of mechanical systems, the original small marine diesel engines are reaching the end of their operational lifespans. Many owners are choosing to repower with compact modern three-cylinder diesels or, increasingly, converting these hulls to clean, lightweight electric propulsion systems, which fit beautifully into the existing shaft-drive configuration. Modernization efforts also frequently focus on installing lithium iron phosphate battery banks, converting to LED lighting, and installing simplified, single-line reefing led aft to the cockpit for safer short-handed sailing.
The Verdict
The Maxfli 28 is a standout example of late-1970s British boatbuilding that successfully brings Julian Everitt's clever racing pedigree into a solid, family-friendly cruising format. While its rarity means buyers will have to search far and wide to locate one, those who do will be rewarded with an exceptionally stiff, comfortable, and well-proportioned cruiser that punches well above its weight class in terms of interior volume and heavy-weather capability. It represents a fantastic value for hands-on sailors looking for a durable, classic pocket cruiser with a touch of vintage style.
Pros:
- High ballast ratio of 42% provides exceptional stiffness and safety.
- Predictable and gentle motion in a seaway due to its moderate-to-heavy displacement profile.
- Generous beam provides a spacious and comfortable cruising interior for a 28-footer.
- Classic British fiberglass construction with a durable, hand-laid hull.
- Agile and responsive handling under power and sail.
Cons:
- Under-canvased in light air without carrying a large, overlapping headsail.
- Extremely rare on the brokerage market, making parts and sister-ship advice difficult to source.
- Balsa-cored decks require careful inspection for moisture intrusion and soft spots.
- Aging original systems and engines often require immediate capital for a complete refit.
- Spade rudder requires active helming on downwind tracks compared to more directional skeg-hung designs.
