Harmony 47 (Poncin) Information, Review, Specs

The Harmony Yachts brand emerged around 2001 as a strategic expansion within the Poncin Yacht Group, formally founded in 2003 by Olivier Poncin. The Harmony 47, entering production in 2005, embodied the group's manufacturing ethos of quality and robustness, essential for the demanding blue-water cruising segment. Designers Mortain & Mavrikios, alongside Olivier Poncin, were instrumental in its conception, with a specific focus on creating boats that possessed an excellent righting moment to enhance navigation comfort and safety. The hull was constructed from fiberglass, emphasizing durability and ease of maintenance. While significant model variations like MkI or MkII are not widely noted, the Harmony 47 offered optional tandem keel configurations and choices in interior and exterior finishes, such as "Elegance" or "Esprit" packages, allowing for a degree of customization [7,.

Sailing Performance and Handling

The Harmony 47 is characterized as a light sailboat that delivers good performance. With a Sail Area to Displacement (SA/D) ratio of approximately 19.41, she is poised to perform well even in lighter air conditions. Her Ballast to Displacement (B/D) ratio of about 33.3% indicates moderate stiffness, contributing to a stable sailing platform. Furthermore, a Displacement to Length (D/L) ratio of approximately 153.15 places the Harmony 47 in the lighter to moderate displacement category, suggesting a design oriented towards efficient performance. She is described as being reasonably stable and stiff, possessing good righting capability. The design philosophy also emphasized a strong righting moment, directly translating to enhanced comfort and safety for cruisers. Equipped with a fractional sloop rig, the Harmony 47 aims to offer a balance of power and ease of handling suitable for various sea states.

Accommodations and Layout

The interior of the Harmony 47 was designed to provide ample living space and comfort for extended voyages, aligning with its blue-water cruising aspirations. Common configurations often featured four cabins and accommodated up to ten berths, making it suitable for larger crews or families. These layouts typically included two heads with showers, enhancing onboard convenience. While specific details on maximum headroom are not consistently documented, the overall design prioritizes comfortable living spaces. Owners had options for customizing the interior and exterior finishes, with "Elegance" and "Esprit" packages providing different aesthetic choices. The vessel's water capacity of 133 US gallons (505 liters) further underscores its design for self-sufficiency during longer passages [2,.
