The boat's debut validated the concept immediately. At Cowes Week 1976, Thomas's own Piccolo trounced most of the quarter-tonners boat-for-boat and then took the production boat trophy at the eighth-ton cup in Lymington. That kind of debut under the International Offshore Rule created instant attention, but Hunter understood that IOR glory alone was no foundation for a long production run; few IOR designs stayed competitive beyond two or three seasons. What made the Sonata special was everything else it brought alongside the race results.
Hull Design and Construction
The Sonata's hull reflects Thomas's deliberate thinking about who would actually sail the boat. He designed her to be, in his own words, a "killer to windward," and achieved this partly through a pronounced tuck in the hull beneath the cockpit. That tuck prevents the boat from breaking free from her quarter wave on downwind legs — which makes her less spectacular in a reaching or running breeze — but it sharpens the effective waterline going upwind in a way that translates directly to boat speed. Thomas explicitly chose a non-planing hull because, as he put it, "we thought too much planing might frighten family crews and granny." It is a candid admission that shaped a genuinely usable boat.
Construction used techniques that were ahead of the production norm at the time. Hunter were among the first companies to use unidirectional and woven rovings in a production boat, which gave the Sonata a hull that is light without being fragile. Structurally the record is clean, though owners should know that the minimal sweep-back on the shrouds contributed to the occasional mast failure in heavy weather on early examples — a known characteristic that later class rules addressed by allowing runners for downwind support.
Production ran from 1976 until 1990, reaching 479 hulls in total. The same basic hull underpinned two further models: the Duette, which used twin fins to allow the boat to dry out upright, and later the Horizon 23.
Rig and Sailing Behaviour
On the water, the Sonata delivers an experience that consistently surprises sailors stepping aboard for the first time. The helm carries what one reviewer described as a "trademark Thomas feel" — not heavy, but with constant, reassuring pressure that keeps the helmsman engaged. She tacks through roughly 75 degrees by the compass in harbour chop and carries very little weather helm at most angles of heel, which means she does not fight the helmsman as conditions build.
Her windward performance on an 18-foot waterline is the boat's headline quality. She sits in a definite groove going to windward, but she is not nervously twitchy about it — lapses of concentration do not punish the way they might on some more highly strung competitors. What she cannot do is match that upwind performance downwind in a blow. The hull design that makes her so effective to weather is, by design, the same feature that caps her downwind pace. Spinnaker sailing in moderate conditions is perfectly manageable; it is only when the breeze builds behind the beam that the non-planing hull becomes a limitation rather than just a characteristic.
The cockpit layout has quirks worth knowing. The traveller, bridging the gap between the seats, is shorter than ideal in standard form, though class rules permit a full-width replacement. A footbar fitted across the cockpit midpoint helps the helmsman brace on the beats, but can become an obstacle during tacks for anyone not used to small-boat choreography.
Accommodation
For a 22-footer designed in the mid-1970s, the Sonata's interior is genuinely generous. Sitting headroom over the saloon bunks runs to a comfortable 40 inches, and there are two further six-foot berths in the forepeak — spaces that on racing Sonatas typically serve as sail stowage. The absence of standing headroom is simply the honest consequence of building a well-proportioned hull of this length; owners who have come to terms with that accept it without rancour.
The accommodation responds well to modest fitting-out. Original owners often added shelves and lockers along the hull sides beyond the standard specification. Racing owners tend to strip back in the other direction, removing weight wherever possible — the standard stainless steel cooker and chemical head being common early casualties. The boat handles both approaches without complaint, which reflects a design that was always intended to serve cruising as readily as racing.
The outboard motor is the one ergonomic compromise that remains genuinely inconvenient. It must be moved in and out of the cabin depending on whether the boat is racing or cruising, because leaving it on the transom adds weight and compromises competitive measurement. It is a small frustration, but a persistent one.
Known Issues and Ownership Considerations
The structural record is largely positive. Apart from the mast-standing issue on earlier boats — which is tied to the shroud geometry rather than any fault in the laminate — the hull has not produced the chronic problems that dog some designs of this vintage. The class has maintained active one-design rules that limit the scope for expensive equipment escalation, which has kept the boat accessible and the racing reasonably level.
The one persistent owner wish is for an inboard engine, which the hull size makes impractical without adding weight and compromising the boat's value in a competitive one-design context. Anyone buying a Sonata primarily to race should accept the outboard arrangement as a given.
The Legacy and Class Life
The Sonata's longevity as a class owes much to decisions made early in its production life. Hunter pursued and received National Class status from the RYA — the first racer/cruiser of her size to receive that recognition — and the boat was selected by the Design Centre in London, a formal acknowledgement of the thinking behind her layout. Both endorsements arrived because the Sonata offered something beyond pure racing performance: she could serve a family on a weekend cruise and then line up in a fleet of thirty or more at Cowes Week the following Tuesday.
That breadth of purpose has kept a substantial number of boats actively sailed and raced decades after production ended. Fleets remain active under CHS and local handicap rules as well as pure one-design formats. The simplicity of the boat — no complicated systems, a straightforward rig, accommodation that is honest rather than aspirational — has meant that maintenance demands stay within reach of ordinary owner-sailors.
The Verdict
The Hunter Sonata is a genuinely coherent design: Thomas knew what he was optimising for and accepted the trade-offs that came with those choices. The non-planing hull, the outboard arrangement, the lack of standing headroom — none of these are oversights. They are the consequence of building a fast, manageable, good-looking 22-footer that families could cruise and racers could campaign without either group feeling short-changed.
Pros
- Exceptional upwind performance for a 22-footer with an 18-foot waterline
- Light but durable hull construction using woven and unidirectional rovings
- Active one-design class with strict rules that limit escalating costs
- Responsive, confidence-inspiring helm with minimal weather helm
- Genuine cruising accommodation for a boat of this size
- Sailed well single-handed
Cons
- Non-planing hull caps downwind speed in a breeze — a deliberate compromise, but a real one
- Outboard must be moved between racing and cruising configuration
- Standard traveller is narrow; full-width replacement is an improvement but adds minor expense
- Early examples can show mast issues linked to minimal shroud sweep-back
- No standing headroom — inherent to the hull proportions, not a build defect
