Design and Construction
The hull and deck are both hand-laid fiberglass, while the deck uses a balsa-cored sandwich intended to moderate the cabin climate. The core also creates the boat’s main structural vulnerability: every deck penetration must be carefully sealed to prevent water from reaching the wood. The balsa-cored sandwich is intended to moderate the cabin climate.
Because some Omega 28s were sold as home-completion kits, finish quality and structural follow-through can vary from hull to hull in ways less likely on a production-line boat. The design combines a lead keel, fractional rig, and fin underbody—a modern-for-its-day, planing-oriented package rather than that of a heavy coastal slug.
Dimensions and Performance
With a length-to-beam ratio of 2.92, the Omega 28 is beamy for its length. Its 2645 pounds of lead ballast, set against roughly 6000 pounds of displacement, produces a ballast ratio near 44 percent.
The capsize screening value is 2.11, which would bar the boat from sanctioned ocean racing under that metric’s rule. A displacement-length ratio of 196 puts it among what reviewers called “moderate racers,” while its 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, while a Bukh diesel variant was calculated at about 4.7 knots. Both drivetrains use shaft drive.
Sail-area-to-displacement is 16.4 using the ISO reference sail and 18.9 with a 135 percent genoa. The relative speed performance index is 62.
Rig and Handling
The fractional sloop rig keeps the masthead unloaded and makes the mainsail dominant. Sail area is 338 square feet. Draft varies with load from 1.58 to 1.68 meters (5.18 to 5.48 ft), allowing the boat to enter most marinas.
With about 269 square feet of wetted surface and an immersion rate of roughly 802 pounds per inch, the Omega 28 sits sensibly in the water for a 28-footer and responds predictably to trim. Its fin keel gives it the maneuvering footprint of a modern small cruiser rather than a long-keel ancestor.
Accommodations
Headroom below is near the class average. Like many boats of its period, the Omega 28 has a teak interior, giving the otherwise conventional small-cruiser cabin a warm appearance.
The layout is better suited to weekend cruising than offshore living. Its near-average standing room reflects a boat proportioned for its length rather than one stretched beyond it.
Known Issues
The principal documented construction concern is the balsa-cored deck. Any through-deck fitting, winch bolt, or antenna mount that penetrates the sandwich must be properly bedded so moisture can’t migrate into the core. If left unsealed, the balsa can deteriorate from within.
The home-completion option adds another variable. On kit-built boats, the original work around deck penetrations may not meet the yard’s standards, and overall build quality can differ among individual hulls.
Verdict
The Omega 28 is a thoughtfully engineered Scandinavian small cruiser. Its fractional rig, lead-ballasted fin keel, and balsa-cored deck were modern features in the mid-1970s.
Buyers must account for the water-sensitive deck core and the variable quality possible among home-completed boats. Apart from those caveats, the figures describe a quick, comfortable coastal cruiser.
Pros
- Beam-forward hull and a ballast ratio near 44 percent
- Fractional rig, with a 135 percent genoa raising sail-area-to-displacement to 18.9
- Hand-laid fiberglass hull and sandwich deck intended to improve cabin comfort
Cons
- Balsa deck core requires meticulous sealing around every penetration
- Home-completed boats may have inconsistent build quality
- Capsize screening value of 2.11 excludes the design from sanctioned ocean racing under that metric
