Design and Construction
Both hull and deck are hand-laid fiberglass, but the deck alone is a balsa-cored sandwich meant to soften the cabin climate anchor. The same core that helps insulation is also the boat's structural Achilles' heel: because balsa sits inside the sandwich, any penetration of the deck must be sealed with real care so water never reaches the wood. A number of Omega 28s were sold as home-completion kits, so the quality of finish and structural follow-through can vary hull to hull in a way a production-line boat would not. The keel is lead, the rig fractional, and the underbody a fin — a modern-for-its-day planing-oriented package rather than a heavy coastal slug.
Dimensions and Performance Character
At a length-to-beam ratio of 2.92 and a ballast ratio near 44 percent, the Omega 28 is beamy and firmly weighted for its size; the 2645 pounds of lead on roughly 6000 pounds displacement give it a capsize screening value of 2.11, which by the rule of that metric would bar it from sanctioned ocean racing. Its displacement-length ratio of 196 places it among what reviewers termed "moderate racers," and the Motion Comfort Ratio of 18.0 suggests a settled ride rather than a soft float. The theoretical hull speed is 6.6 knots; a Yanmar YSM8G-powered example was clocked at 7.3 knots and a Bukh diesel variant calculated near 4.7, with both drivetrains using shaft drive. Sail-area-to-displacement reads 16.4 on the ISO reference sail and 18.9 with a 135 percent genoa, and the relative speed performance index lands at 62.
Rig and Handling
The fractional sloop rig keeps the masthead unloaded and the mainsail dominant, a configuration that pairs with the 338 square feet of sail area and the draft of 1.58 to 1.68 meters (5.18 to 5.48 ft) dependent on load to let the boat slip into most marinas. With a wetted surface near 269 square feet and an immersion rate of about 802 pounds per inch, she sits sensibly in the water for a 28-footer and responds predictably to trim. The fin keel gives her the maneuvering footprint of a modern small cruiser rather than a long-keel ancestor.
Accommodations
Below, headroom is near the average for the class, and the interior is teak like most contemporaries — a warm but otherwise conventional small-cruiser cabin. The layout serves weekend cruising rather than offshore living, and the near-average standing room confirms a boat sized for its length rather than stretched beyond it.
Known Issues
The one documented construction caveat is the balsa-cored deck: any through-deck fitting, winch bolt, or antenna mount that breaches the sandwich must be bedded so moisture cannot migrate to the core. Left unsealed, the balsa will degrade from within, and because some hulls were home-finished, the original penetration work may not meet yard standards.
The Verdict
The Omega 28 is a thoughtfully engineered Scandinavian small cruiser whose fractional rig, lead-ballasted fin, and balsa-cored deck read as ahead of its mid-seventies moment. The home-completion option and the water-sensitive deck core are the two caveats a buyer must respect; otherwise the numbers describe a quick, comfortable coastal boat.
Pros
- Beam-forward hull with 44 percent lead ballast for stability
- Fractional rig with genoa option lifts sail-area-to-displacement to 18.9
- Hand-laid glass hull with sandwich deck for cabin comfort
Cons
- Balsa deck core demands meticulous through-deck sealing
- Home-completed hulls may show inconsistent build quality
- Capsize screening of 2.11 excludes it from ocean racing
