Design and Construction
Blomstergren gave the Trio 92 a solid, hand-laid fiberglass hull with a negative stern. The spade rudder hangs on an internal skeg arrangement, while the lead fin keel is carried on a fiberglass blade.
Her 9.2 m overall length is paired with a 7.45 m waterline, 3.2 m beam, and 1.73 m draft, increasing to 1.83 m under load. The boat displaces 3,700 kg and carries 1,800 kg of lead ballast. That produces a ballast ratio of 49 percent, which period analysis confirms gives her a firmly weighted keel for her size.
A length-to-beam ratio of 2.87 and a displacement-length ratio near 256 further define the Trio 92 as a moderately heavy, beamy design. Her wetted surface is roughly 28 m², and an immersion rate of 159 kg/cm describes a hull that settles predictably as stores and crew come aboard.
Rig and Sail Plan
The Trio 92 has a masthead rig with a through-deck mast. Sail area includes a 19 m² mainsail and a 35 m² genoa, with a second 28 m² genoa also listed. For downwind sailing, she carries a 75 m² spinnaker.
The sail-area-displacement ratio is 15.9 with the reference sail plan and 19.1 with a 135 percent genoa. Writing in yachtdatabase.com, one reviewer noted that the Trio 92 carries more rig than only 31 percent of comparable sailboats, suggesting that she is slightly underrigged for her displacement. Her SRS rating is 0.927, dropping to 0.904 without downwind sails.
Running-rigging dimensions are thoroughly documented. The mainsail and genoa halyards are each 28.7 m long and 10 mm in diameter. Jib and genoa sheets measure 9.2 m at 12 mm, while the mainsheet is 23 m at 12 mm.
Performance and Seakeeping
The Trio 92’s calculated maximum speed is about 4.9 knots, compared with a theoretical displacement-hull speed of 6.6 knots. Her Relative Speed Performance index is 46, while the Motion Comfort Ratio ranges from 20.9 to 22.0. Together with the sail-area ratios, these figures describe a modestly powered boat balanced for relaxed sailing rather than all-out pace.
Her capsize screening value of 2.05 means she wouldn’t be accepted in ocean races, placing her firmly in the coastal-cruiser category.
Accommodations
Below, the Trio 92 has a teak interior and 1.85 m of cabin headroom, described as above average for the class. The galley is to starboard and the navigation station to port. A quarter berth behind the navigation seat also provides seating at the chart table.
The saloon has a slight U-shaped settee and a straight settee. Forward, the forepeak contains two full-length berths, with the toilet positioned between the saloon and bow.
Sources disagree on total berth capacity: one lists four, while another gives six. Depending on how the settees are used, the layout can accommodate a small family or two couples for coastal cruising.
Verdict
The Trio 92 is a compact, well-ballasted Swedish cruiser with honest construction and a practical teak interior. Her rarity reflects a brief and turbulent production run. She is best suited to sheltered-water and coastal cruising rather than offshore passage-making.
Pros
- Lead fin keel and a ballast ratio near 49 percent for stiffness
- Above-average headroom and a full teak interior
- Well-documented, rational sail-control dimensions that simplify rig upkeep
Cons
- A capsize screening value of 2.05 excludes her from ocean racing
- Slightly underrigged compared with similar 30-foot sloops
- Fewer than 100 built, limiting spares and fleet support
