About the Cape Dory 27 Sailboat

Designed by renowned naval architect Carl Alberg, this classic 27-footer exemplifies traditional American cruising yacht design from the late 1970s and early 1980s. Cape Dory built 277 of these sturdy vessels between 1977 and 1985, establishing a reputation for solid construction and seaworthy handling that continues to attract devoted owners today. The boat's full keel with attached rudder configuration provides exceptional tracking and directional stability, making it an excellent choice for coastal cruising and short-handed sailing. With a displacement of 7,500 pounds and 3,000 pounds of ballast, this masthead sloop offers the kind of motion comfort that made Cape Dory famous among cruising sailors. The generous beam of 8.5 feet provides surprising interior volume for a 27-footer, while the moderate draft allows access to many shallow anchorages. Carl Alberg's design philosophy emphasized seaworthiness over speed, and this boat delivers exactly that. The conservative sail area and robust construction make it forgiving for newer sailors while providing the reliability experienced cruisers demand. Though not built for racing, its excellent comfort ratio of 30.28 and favorable capsize screening numbers reflect its suitability for serious coastal exploration and weekend cruising adventures.

The deck hardware on Cape Dory 27s is typically through-bolted into balsa-cored deck sections. Water intrusion around chainplates, stanchion bases, and cleats causes balsa core rot that can be widespread before it becomes visible. Compression testing and core sampling around all deck fittings is essential.
High
The external lead keel is attached with bronze keel bolts that can corrode or loosen over time. The joint between the keel and the fiberglass sump is prone to cracking and water intrusion, allowing water to sit against the keel bolts internally. Inspection of bilge area around keel stub for weeping or staining is critical.
High
Most Cape Dory 27s were fitted with the Universal Atomic 4 gasoline engine. This engine is aged, carbureted, and presents fire risk if fuel system components (rubber fuel lines, carb gaskets, fuel pump diaphragm) are not regularly replaced. Many owners have converted to small diesel auxiliaries; verify engine type and condition before purchase.
