Cape Dory 27 Information, Review, Specs

Sailing Performance & Handling

The Cape Dory 27 is a displacement-oriented cruiser that excels when the wind picks up, offering a stable and predictable ride that lighter, modern fin-keel boats often lack. With a displacement of 7,500 pounds and a ballast-to-displacement ratio of 40%, the vessel carries its weight in a full keel with an encapsulated lead ballast. This configuration provides exceptional directional stability, allowing the boat to "track" effectively on long reaches with minimal helm correction.

Technical ratios reveal a boat designed for comfort rather than light-air racing. The Sail Area-to-Displacement (SA/D) ratio typically hovers around 15.1, which indicates a need for more breeze to get the hull moving compared to contemporary performance cruisers. However, as noted in technical evaluations by the Cape Dory Owners Association, the boat’s narrow 8’6” beam and 4’0” draft allow it to heel to a certain point and then "stiffen up," providing a secure feel in heavy weather.

Handling under power can be challenging for those accustomed to spade rudders. The full keel and aperture-mounted propeller mean the boat has a significant turning radius and exhibits pronounced "prop walk" in reverse. Sailors often report that the CD27 requires a proactive approach to maneuvering in tight marinas, often relying on the boat's momentum rather than quick bursts of throttle.

Interior Comfort & Variations

For a 27-foot boat designed in the mid-1970s, the interior of the Cape Dory 27 is remarkably functional, though it reflects the narrow hull proportions of the era. It provides approximately 6 feet of headroom, which was a significant upgrade over the smaller Cape Dory 25. The layout is a classic "four-berth" configuration: a forward V-berth, a head compartment with a hanging locker, and a main salon featuring two longitudinal settees.

The use of high-quality materials is a hallmark of the builder. The interior is heavily accented with solid teak and teak veneers, which, when combined with the signature bronze opening ports from Spartan Marine, creates a warm, traditional nautical ambiance. The galley is typically located aft, split between the port and starboard sides of the companionway, providing a secure spot for the cook while underway.

Sibling models built on similar design philosophies include the Cape Dory 25D (a "diesel" version with a redesigned hull) and the Cape Dory 28. While the CD27 shares the Alberg aesthetic with the 28, the 28 offers a slightly beamier hull and a different deck mold, providing a more spacious feel at the cost of the 27's more nimble proportions.

Known Issues & Buyer’s Checklist

Prospective buyers should focus their inspections on the specific structural characteristics of 1970s and 80s fiberglass construction.

1. Chainplate Leaks: Like many boats of this vintage, the chainplates pass through the deck and are prone to slow leaks. If left unaddressed, this moisture can migrate into the plywood bulkheads, leading to rot and structural compromise.
2. Balsa Core Integrity: The decks are cored with balsa. Testers and owners frequently cite "soft spots" around the mast step and stanchion bases. A thorough percussion test (hammer sounding) or moisture meter reading is essential during a survey.
3. Engine Access and Maintenance: Most CD27s were equipped with the Westerbeke 10 or Volvo Penta diesel engines. While reliable, these units are now decades old. Buyers should check the cooling system and exhaust riser for corrosion, as parts for older Volvo models can be expensive and difficult to source.
4. Rudder and Aperture: The rudder is attached to the trailing edge of the keel. Inspect the bronze gudgeons and the fiberglass around the propeller aperture for signs of stress cracking or delamination.
5. Bronze Portlights: While the Spartan Marine bronze ports are a premium feature, the gaskets eventually dry out and leak. Replacing these gaskets is a common "first project" for new owners.

Community & Resources

The Cape Dory 27 benefits from one of the most dedicated owner communities in the American sailing world. The Cape Dory Owners Association (CDSOA) serves as a massive technical clearinghouse, offering original brochures, wiring diagrams, and a robust forum for maintenance advice. Because many Cape Dory models share hardware produced by Spartan Marine, owners can still source authentic replacement parts through the Spartan Marine division, which survived the original company’s closure.

The Verdict

The Cape Dory 27 is an ideal vessel for the traditionalist who prioritizes build quality and heavy-weather safety over interior volume and light-air speed. It remains a premier choice for solo sailors or couples looking for a "forever boat" capable of coastal cruising and occasional offshore hops.

Pros:

• Exceptional Build Quality: Solid fiberglass hull and high-grade bronze hardware.
• Sea-kindly Motion: Full-keel design provides a comfortable ride in choppy conditions.
• Timeless Aesthetics: Classic Alberg lines that retain resale value and "dock appeal."
• Strong Support: Excellent owner association and availability of original hardware.

Cons:

• Tight Interior: Narrow beam makes the cabin feel smaller than modern 27-footers.
• Slow in Light Air: High displacement and conservative sail plan require a stiff breeze.
• Difficult Reverse: Full-keel maneuverability in tight quarters requires practice.
