Jonmeri 33 Buyer's Guide
The Jonmeri 33, sometimes seen listed as the Jon Meri 33, is a 33-foot masthead sloop designed by Jorma Nyman and built by Maestro Boats with at least one other yard involved in production. For a shopper scanning the used market, she presents as a solid fiberglass cruiser with about 200 hulls produced from 1979 onward, six berths below, and a rig that makes gear replacement straightforward.
Layouts on the Used Market
Jonmeri 33 hulls were produced at more than one yard, so interior fit and minor detailing can vary from boat to boat even though the core layout delivers six berths in a 33-foot sloop. A buyer should treat each example as a slightly individual specimen rather than assuming uniform factory specification across the fleet.
Equipment and Common Upgrades
The boat may be fitted with a 30-horsepower diesel, a meaningful item to confirm on any candidate since it drives charging and propulsion expectations. Beyond that, the period specifications give full rig dimensions — halyards near 102 feet on 3/8-inch, sheets on 1/2-inch — so a used boat with replaced running rigging should be checked against those lengths rather than assumed correct.
What to Inspect
Because the boat was built at other yards as well, inspect for specification drift — fasteners, deck hardware bedding, and rigging terminals may not match a single factory standard, so compare the example in front of you against the rig measurements rather than a presumed norm. Confirm the bulb keel profile on the specific hull through hull-number records or haul-out photos before committing.
Availability and Buyer's Takeaway
- Confirm the keel profile on the specific hull before purchase
- Check running rigging lengths against documented specs
- Verify diesel horsepower and condition on viewing
- Inspect deck hardware bedding for yard-to-yard variation
