The Twister 28 is widely regarded as one of the most successful small offshore cruisers ever designed, a masterpiece from the board of naval architect Kim Holman. Originally conceived in 1963, the design’s reputation was cemented when Holman’s own boat, Twister of Mersea, dominated the East Coast racing circuit. While the design began as a bespoke wooden build at the J.W. & A. Upham yard in Brixham, its success necessitated a transition to semiproduction construction. This evolution saw the Twister move from traditional clinker or carvel wooden hulls to a "composite" construction—featuring a GRP hull molded by the Tyler Boat Company with wooden decks and coachroofs finished by Upham—and eventually to the full GRP Mk II version. This vessel represents the pinnacle of the "English Folkboat" evolution, offering a more powerful, spacious, and seaworthy alternative to its predecessors while maintaining the timeless aesthetics of a traditional longkeeled yacht.

Sailing Performance & Handling

The Twister 28 is defined by its exceptional sea-kindliness and an "all-weather" capability that belies its modest length. With a displacement-to-length ratio that leans toward the heavy side and a ballast ratio often exceeding 45%, the boat is remarkably stiff. This stability is largely due to its deep-V hull sections and a heavy encapsulated lead or iron keel. According to technical assessments by Yachting Monthly, the Twister tracks with remarkable precision, a direct benefit of its long keel, which allows the helmsman to leave the tiller for extended periods even without an autopilot.

Under sail, the boat is not a light-air flyer, but it comes alive when the breeze freshens. It handles a blow with grace, maintaining a predictable motion in a head sea where lighter, modern designs might slam. The rig—typically a masthead sloop—is manageable and robust. While it lacks the sheer speed of modern fin-keelers on a racecourse, its ability to maintain a high average speed in rough conditions makes it a favorite for "short-handed" coastal and blue-water voyaging. Its sibling, the Stella, served as a smaller, more racing-oriented predecessor, but the Twister 28 refined those lines into a true offshore thoroughbred.

Interior Comfort & Variations

The interior of the Twister 28 reflects the era of its birth: functional, cozy, and built with traditional maritime sensibilities. The layout generally accommodates four berths, consisting of a V-berth in the forward cabin and two settee berths in the main saloon. Because the hull features deep-V sections, the floorboards are set low, which provides surprising headroom (roughly 5'11" or 1.8m) for a 28-foot yacht of this vintage.

Materiality varies significantly between the different "marks" of the boat. The early Upham-built composite models are prized for their high-quality mahogany joinery and traditional atmosphere. In these versions, the warmth of the wood offsets the compactness of the galley, which is typically located aft to one side of the companionway. The full-GRP Mk II models, while often more practical regarding maintenance, sometimes lack the intricate timber detailing found in the earlier Brixham builds. Storage is plentiful for a boat of this size, intended for genuine cruising rather than mere day-sailing, though the narrow beam (8' 1") inherently limits the "social" space in the saloon compared to modern wide-stern designs.

The Twister 28 occupies a legendary status in British yachting literature and has been the vessel of choice for several high-profile long-distance sailors. Most notably, Trevor Robertson spent years living aboard and voyaging in the Arctic and Antarctic on his Twister, Iron Bark, demonstrating the model's incredible resilience in extreme environments. The boat is also a frequent subject in the works of nautical writers who prize the Holman design philosophy of "beauty that works." The Twister Class Association maintains an extensive archive of these voyages and historical milestones, documenting the boat's transition from a regional racer to a global cruiser.

Known Issues & Buyer’s Checklist

Prospective buyers should prioritize an inspection of the hull-to-deck join, particularly on "composite" models. These versions feature a wooden coachroof and deck mated to a GRP hull; over decades, the different expansion rates and fastener fatigue can lead to persistent leaks or freshwater rot in the deck beams and carlings.

  • Osmosis: Early Tyler-molded hulls are known for high-quality laminates, but like all GRP boats from the 1960s and 70s, they should be checked for osmotic blistering, especially if they have been kept in warmer waters.
  • Chainplates and Rigging: The original chainplate attachments should be inspected for "crevice corrosion" or movement, as the Twister’s rig exerts significant tension on these points during heavy weather.
  • Engine Access: Many Twisters were originally fitted with small Stuart Turner or Petter diesels. While many have been repowered with modern Betas or Yanmars, the engine space is notoriously tight, making routine maintenance tasks like impeller changes a challenge.
  • Rudder Stock: The transom-hung or semi-skeg rudders are robust, but the pintles and gudgeons can develop play over time, leading to a "knocking" sensation in the tiller that requires bushing replacement.

Community & Resources

The Twister community is exceptionally active, centered primarily around the Twister Class Association (TCA). This organization is a vital resource for owners, providing technical drawings, historical registries of hulls built at Upham’s, and a network of experts who specialize in the restoration of Kim Holman designs. The association organizes annual rallies, particularly on the South Coast of England, where the sight of a dozen Twisters together remains a common and celebrated occurrence.

The Verdict

The Twister 28 is a "sailor’s sailboat," offering a level of security and aesthetic satisfaction that few modern production boats can match. It is an ideal choice for the traditionalist who values sea-kindliness over interior volume.

Pros:

  • Exceptional heavy-weather performance and directional stability.
  • Timeless, elegant lines that draw admiration in any marina.
  • High build quality, particularly those finished at the Upham yard.
  • Strong resale value and a dedicated class association.

Cons:

  • Narrow interior and limited beam by modern standards.
  • Composite models require significant maintenance of wooden upperworks.
  • Tight engine compartments make mechanical work difficult.
