Jonmeri 33
Description
The Jonmeri 33 is a Finnish fiberglass cruising sailboat designed by Jorma Nyman for Jonmeri Yachts (Jonmeri Oy) in Jakobstad, Finland, with production starting in 1979 and continuing into the 1980s (exact end date varies by source, but around 200 hulls built total). It features solid fiberglass (GRP) construction with a fin keel (with bulb) and spade rudder for balanced performance and stability, a masthead sloop rig, and a reputation for reassuring seaworthiness, excellent craftsmanship, and comfort suitable for serious coastal/offshore cruising or club racing—often described as a "fantastic family cruiser" with nice lines, well-balanced handling in all conditions, and high structural standards typical of Scandinavian builds.
