Design and Construction
Blomstergren’s hull is solid hand-laid fiberglass with a negative stern and a spade rudder hung on an internal skeg arrangement, while the fin keel is lead on a fiberglass blade. The 9.2 m overall length sits on a 7.45 m waterline, with 3.2 m beam and 1.73 m draft that can reach 1.83 m under load. The wetted surface of roughly 28 m² and an immersion rate of 159 kg/cm describe a hull that settles predictably with stores and crew. The 49 percent ballast ratio from period analysis confirms a firmly weighted keel for her size.
Rig and Sail Plan
The Trio 92 is a masthead sloop with a through-deck mast, carrying 19 m² in the mainsail and a 35 m² genoa (a second 28 m² genoa is listed), plus a 75 m² spinnaker for downwind work. Halyard and sheet dimensions are thoroughly documented: the mainsail and genoa halyards run 28.7 m at 10 mm, jib and genoa sheets are 9.2 m at 12 mm, and the mainsheet is 23 m at 12 mm. The sail-area-displacement ratio is 15.9 on the reference sail and 19.1 with a 135 percent genoa; writing in yachtdatabase.com, one reviewer noted she carries more rig than only 31 percent of similar sailboats, suggesting she is slightly underrigged for her displacement. Her SRS rating is 0.927, falling to 0.904 without downwind sails.
Performance and Seakeeping
Calculated maximum speed is about 4.9 knots against a theoretical displacement-hull speed of 6.6 knots, and the Motion Comfort Ratio spans 20.9 to 22.0. The capsize screening value of 2.05 means she would not be accepted in ocean races, placing her firmly in the coastal-cruiser category. The Relative Speed Performance index of 46 and the sail-area ratios together describe a boat that is modestly powered but balanced for relaxed sailing rather than all-out pace.
Accommodations
Below, the interior is teak throughout with 1.85 m cabin headroom described as above average for the class. The galley is to starboard and the navigation station to port, with a quarter berth behind the nav seat that doubles as seating at the chart table. The saloon holds a slight U-settee and a straight settee, while the forepeak offers two full-length berths and a toilet sits between saloon and bow. Berth counts differ between sources — one lists four, another six — so the layout supports a small family or two couples in coastal comfort depending on settee use.
The Verdict
The Trio 92 is a compact, well-ballasted Swedish cruiser with honest construction and a practical teak interior, limited in numbers and built during a brief, turbulent production run. She suits sheltered-water and coastal cruising rather than offshore passage-making.
Pros
- Lead fin keel with near-49 percent ballast ratio for stiffness
- Above-average headroom and full teak interior
- Documented, rational sail-control dimensions for easy rig upkeep
Cons
- Capsize screening of 2.05 excludes her from ocean racing
- Slightly underrigged relative to similar 30-foot sloops
- Fewer than 100 built, limiting spares and fleet support
