About the JONMERI 33
Design updated by Strahlman.
The Jonmeri 33 is a robust cruising sloop designed by Jorma Nyman/Strahlman and built by Jonmeri, with a production run of 200 hulls completed in 1979. Its substantial displacement of 13228.0 lb and high D/L ratio of 314.83 reflect a heavy, stable platform intended for serious offshore passage-making.
- Best for:
- This boat is best suited for experienced coastal and offshore cruisers who prioritize seakeeping and comfort over high-speed performance, particularly those willing to manage the maintenance demands of a 1970s fiberglass construction.
- Bluewater capability:
- With a low capsize ratio of 1.86 and a comfort ratio of 29.45, the Jonmeri 33 is well-regarded for bluewater cruising, though owners report significant structural concerns regarding deck core moisture and keel integrity that must be addressed before offshore passage.
- Comparables:
- Comparable boats include the Hallberg-Rassy 33 and the Tartan 33, as they share similar heavy-displacement characteristics, fin keel configurations, and a reputation for solid offshore capability within the 33-foot cruising segment.
