This transition also marked the widespread implementation of Ericson’s signature Tri-Axial Force Grid (TAFG). Rather than relying on traditional wood stringers or a basic fiberglass liner, the TAFG utilized an engineered, molded fiberglass floor frame network bonded directly to the hull. This structural grid effectively distributed the immense loads of the keel and the rig throughout the entire hull structure. For the buyer of the era, the Ericson 28+ offered an unparalleled mix of structural rigidity, interior space, and lively Bruce King performance that set it apart from contemporary cruisers like the Catalina 27 or the O'Day 28.
Design Brief & Intent
The Ericson 28+ was conceived as an athletic, near-shore cruiser-racer tailored for sailing families and club racers. Bruce King's mandate was to optimize interior volume and cruiser comfort without sacrificing the sailing qualities that Ericson owners demanded. To achieve this, the design utilizes an expansive 10.5-foot beam, which was unusually wide for a boat under 29 feet in the early 1980s. This generous beam allowed King to push the accommodation spaces outward, creating an open-plan cabin that feels remarkably spacious.
Stepping below, the cabin's layout is traditional yet highly functional, boasting an impressive headroom of roughly six feet two inches along the centerline—a dimension that easily accommodates taller sailors who are typically forced to hunch in other 28-footers. The interior is warm and richly appointed, showcasing Ericson’s high-quality teak joinery and cabinetry 6. Accommodation includes a traditional V-berth forward with privacy doors, a central salon featuring opposing settee berths, and a fold-down dining table that mounts flat against the bulkhead to maximize cabin floor space when not in use. A functional U-shaped galley is situated to starboard of the companionway, while a dedicated navigation station and a roomy quarter berth sit to port. This layout makes the boat highly livable for a couple or a small family on extended weekend cruises, placing it a tier above its more spartan competitors of the same vintage.
Variations & Configurations
While the hull and deck footprint of the Ericson 28+ remained consistent throughout its four-year production run, the model was offered with a few critical configurations to suit regional sailing conditions. Below the waterline, the standard draft option was a deep fin keel drawing 5.0 feet, which offered the best upwind performance and lift. For sailors navigating the thin-water areas of the East Coast, the Chesapeake, or Florida, Ericson offered a shoal-draft keel drawing 4.0 feet.
The boat was standard with a fractional sloop rig, utilizing a highly tunable, tapered mast with swept-back spreaders 9. This configuration was engineered to allow precise control over mainsail draft and mast bend. Auxillary power was typically provided by a small, reliable inboard diesel engine. Most boats left the factory with an 11-horsepower Universal M-15 or M-12 engine, though some late-production models were delivered with Yanmar powerplants.
Sailing Performance & Handling
Under sail, the Ericson 28+ behaves like a true sailor's boat, rewardingly responsive to subtle sail trim. With a sail area to displacement ratio of 17.62, the 28+ is moderately powered and performs beautifully in light to moderate air, especially when paired with a larger 150% genoa 3. The boat is quick to accelerate and points exceptionally well upwind, holding a tight tacking angle and easily reaching speeds of 5.5 to 6 knots in a 12-knot breeze.
The boat's displacement to length ratio of 237.13 places it firmly in the moderate displacement category, ensuring it carries enough momentum to punch through light chop without stalling 3. However, with a comfort ratio of 19.86 and a capsize screening ratio of 2.15, the 28+ is fundamentally a coastal cruiser rather than a heavy displacement ocean voyager. It has a lively motion in a seaway and is relatively tender initially. The boat is designed to heel early to about 20 degrees, at which point its wide beam and 40% ballast-to-displacement ratio (provided by 3,000 pounds of external lead ballast) combine to provide strong secondary stability. Because it heels early, short-handed crews should plan to reef the main early—typically when true wind speeds push past 12 to 15 knots—to prevent excessive weather helm and keep the deep spade rudder fully effective.
Known Issues & Triage
As with any vessel built in the early 1980s, the Ericson 28+ has several age-related areas that demand thorough inspection. The most common structural concern is the "Ericson Smile," a hairline crack that can develop at the forward leading edge of the keel-hull joint where the lead keel meets the fiberglass stub. While this is often a cosmetic issue caused by the slight flexing of the joint over decades of use, it must be carefully inspected to ensure there is no structural movement or water weeping.
Another critical inspection area is the deck coring. Like most production builders of the era, Ericson utilized end-grain balsa coring in the deck construction. Moisture ingress around original deck hardware, the mast step, stanchion bases, and the chainplates can lead to localized core rot and soft spots. Chainplates, which pass directly through the deck to the structural bulkheads, are particularly prone to slow leaks that can rot the bulkheads if left un-rebedded.
Furthermore, while the Tri-Axial Force Grid is a major engineering strength, a prospective buyer must inspect the bilge to ensure the grid has not separated from the hull. Though rare, a violent, high-speed grounding can pop the fiberglass tabbing that bonds the grid to the hull liner. If the tabbing has fractured, it requires a meticulous grinding and re-glassing job to restore the boat's original structural rigidity.
Modernization & Upgrades
Due to the high build quality of the hull and the continuing support of an active owner's association, many Ericson 28+ models have been extensively modernized by their owners. The most significant upgrade is typically engine repowering. The original 11-horsepower Universal diesels are now decades old, and many owners choose to replace them with modern, lightweight two- or three-cylinder diesels, such as the Beta Marine 14 or 20, which fit easily into the existing engine compartment and offer vastly improved reliability and parts availability.
Electrical overhauls are also common. Owners frequently replace the original, basic DC panels and aging wiring with modern blue-sea distribution panels, high-output alternators, and lithium iron phosphate (LiFePO4) battery banks to support modern refrigeration and electronics at anchor. Other highly recommended upgrades include replacing the original aluminum-framed opening ports—which are prone to leaking—with new stainless steel or polymer replacements, upgrading to a dripless PSS shaft seal, and running all halyards and reefing lines aft to the cockpit to make the boat an effortless single-handed pocket cruiser 5 8.
The Verdict
The Ericson 28+ remains one of the finest, most well-rounded entry-level coastal cruisers on the brokerage market. Bruce King’s masterclass in interior packaging allowed the boat to deliver the comfort and accommodations of a 30-footer, while the fractional rig and balanced hull profile keep the sailing experience lively and highly rewarding. For a cruising couple or small family seeking a solid, elegant, and agile boat for coastal hops, the 28+ represents an exceptional value that punches far above its weight class.
