Naval architects Mortain & Mavrikios drew the design, and Groupe Poncin Yachts built the yacht from around 2004 to 2008. The 47-foot model later became a familiar charter boat in the Greek islands and across the wider Mediterranean.
Design and Construction
The hull is fiberglass-reinforced polyester, built using vacuum-infused sandwich construction around a PVC foam core. This method keeps seasonal maintenance to a minimum.
During lay-up, the ribs are pre-positioned and become integral with the hull when the resin is injected, creating a notably stiff structure. Kevlar reinforcement in the high-stress keel zone provides a further safety margin. Experienced skippers who operated Harmony 47s in charter fleets praised the solid construction and described the boats as quick and vice-free.
Two keel configurations were offered. The standard deep fin gives roughly 2.10 to 2.20 meters of draft, while the tandem shallow cast-iron keel draws just 1.60 meters. The shoal-draft version opens up more cruising grounds, although discussions note that it reduces stability and motion comfort compared with the deeper configuration.
Rig and Handling
The standard fractional sloop rig carries a full-batten mainsail with lazy jacks and a roller-furling genoa on a Facnor headsail system. Lewmar 44 ST winches handle the sheets, while Lewmar 40 ST winches handle the halyards. A quick-release wheel on a slim helm pedestal is a practical touch. However, the charter version has drawn criticism for having only two cockpit winches.
Performance
With a displacement/length ratio of 153, the Harmony 47 falls into the light-racer band; 82% of comparable sailboats are heavier. Its sail-area-to-displacement ratio of 19.41 puts it in the cruiser-racer category. The theoretical hull speed is 8.6 knots over a 12.47-meter waterline.
The ballast ratio, at 33%, is on the lower side, while the Motion Comfort Ratio of 25.4 falls in the lower quartile for the type. The yacht carries CE Class A (ocean) certification and has a capsize screening value of 1.95.
Accommodation
Below deck, the Harmony 47 has four cabins, sleeps eight to ten people, and provides two heads. The interior is finished in wood and white lacquer and reads as tasteful and modern.
The galley is arranged for extended cruising, with a work surface, drained sink, cooker, and double-door fridge. Owners have also singled out the large anchor locker, fold-down transom with boarding ladder, and substantial fridge as useful practical details. Fresh-water capacity is about 500 liters.
Known Issues and Ownership Considerations
A rigging surveyor with direct experience of three charter-operated Harmony 47s described them as problematic and poor at aging. Rigging has also been flagged as a concern on well-used examples, regardless of their documented service history.
The main charter-specific concern is accelerated wear from heavy use. With production now ended, the smaller dealer and parts network relative to competing brands is another material ownership consideration.
Verdict
The Harmony 47 is a thoughtfully engineered, light-displacement cruiser-racer. Its vacuum-infused sandwich construction, stiff integral structure, and modern interior are important strengths, and the interior wears well in service. The shoal keel broadens access to cruising grounds, but at a cost in stability and motion comfort. Its charter pedigree also means a prospective buyer must account for potentially heavy wear and a thinner support network than those of the dominant production marques.
Pros
- Vacuum-infused, PVC-core hull with integral ribs and Kevlar reinforcement in the keel zone
- Light-racer displacement, a cruiser-racer sail plan, and an 8.6-knot theoretical hull speed
- Four-cabin layout, modern lacquered interior, and practical galley and cockpit details
- CE Class A ocean certification and a capsize screening value of 1.95
Cons
- Lower-quartile Motion Comfort Ratio and a 33% ballast ratio
- Rigging flagged as a concern on well-used boats, with accelerated charter wear
- Shallow keel reduces stability and motion comfort
- Smaller dealer and parts network since production ended
