Jonmeri 482 Information, Review, Specs

The Jonmeri 482 began its production run in 1988, extending its availability in the market until 2012. The design of the Jonmeri 482 evolved from its predecessor, the Jonmeri 48, with the firm making modifications to the established 48-foot model. This evolution notably included the integration of a new rudder and keel, a redesigned sail plan, and alterations to the layout of the sub-deck areas, aiming for a lighter and more maneuverable vessel. Karl-Johan Stråhlmann, a key designer, played a significant role in these refinements, contributing to the yacht's modern performance while upholding its inherent stability and offshore capabilities 1, 2, builder article. A notable variation includes a "Deck Salon" version, also known as the Jonmeri 48, and the availability of multiple keel options, allowing owners to tailor the yacht to their specific cruising needs.

Sailing Performance and Handling

With a sail area to displacement ratio of approximately 15.70, the Jonmeri 482 demonstrates a moderate performance profile, indicating a capable cruiser rather than a light-air racer. Her substantial ballast-to-displacement ratio of around 0.430, combined with a lead fin keel and spade rudder, contributes significantly to her stiffness and stability, enabling her to stand up well to a breeze and providing a comfortable motion in a seaway. The displacement to length ratio, calculated at a notably high 565.8, categorizes the Jonmeri 482 as a very heavy displacement yacht. This characteristic underscores its design as a solid, traditional offshore cruiser, prioritizing comfort and safety over outright speed. Owners often find the Jonmeri 482 to be a well-mannered boat, capable of handling diverse sea states with confidence, reflecting the designer's intent for a "spacy hull design" suitable for extensive cruising.

Accommodations and Layout

While specific interior headroom data for the Jonmeri 482 is not readily available, the vessel is known for its spacious and well-appointed living areas, aligning with Jonmeri Yachts' reputation for creating high-quality, comfortable offshore vessels. The design modifications of the 482 included changes to the layout of the sub-deck areas. The Jonmeri 48, closely related to the 482, has been noted for offering the interior layout advantages typically associated with center cockpit designs, even with an aft cockpit configuration, suggesting generous interior volume and thoughtful use of space. Consistent with Finnish boatbuilding standards, the interior typically features high-quality materials and hand-built craftsmanship, providing a durable and elegant finish. The layout generally includes ample storage, a functional galley, comfortable sleeping berths, and a proper head, designed to maximize comfort and practicality for extended voyages.
