Designed by Csj Roy and built by Atlanta Marine in the UK starting in 1977, this 28-footer stands out as a practical coastal cruiser with distinctive twin-keel configuration. The twin keels provide excellent stability in shallow waters and allow the boat to sit upright when beached or dried out, making it particularly appealing for exploring tidal areas and shallow anchorages where traditional deep-draft boats cannot venture. With a displacement of 7,286 pounds and substantial ballast of 3,500 pounds, the Atlanta 28 offers reassuring stability for coastal cruising. The masthead sloop rig carries 275 square feet of sail area, providing adequate power for leisurely sailing while remaining manageable for small crews. Her beam of 9.16 feet creates reasonable interior volume for weekend cruising, while the moderate draft of 4.67 feet (when keels are down) allows access to a wide range of harbors and anchorages. The comfort ratio of 23.66 suggests this is a motion-conscious design suited to those who prefer steady, predictable sailing characteristics over racing performance. The capsize screening formula of 1.89 indicates good stability margins for coastal waters. This fiberglass construction boat appeals particularly to sailors seeking shoal-water capability without sacrificing seaworthiness for protected coastal exploration.
