The Cape Dory 25D arrived in the fall of 1981 as Carl Alberg’s reworking of the original Cape Dory 25. Compared with George Stadel III’s earlier design, it had a beamier, deeper, and heavier hull, plus an inboard diesel—the “D” stands for diesel.

Practical Sailor described the 25D both as a miniature cruising yacht and as a serious cruising boat in miniature. This heavy-displacement 25-footer was conceived less as a daysailer than as a pocket voyageur. Cape Dory produced 189 hulls from 1981 to 1985. As Alberg’s replacement for the Stadel 25, the 25D retained the marque’s solid-glass construction ethos while pushing the concept toward genuine offshore capability.

Design and Construction

The 25D stands out for its thorough glasswork and ballast encapsulation. The hull is a moderately heavy, solid layup of mat and roving. Its lead ballast casting sits in a hollow keel molding; the surrounding voids are filled with polyester slurry and heavily glassed over inside the hull.

The decks and cabin top are cored with end-grain balsa, and the deck is bonded to the hull with a semi-rigid polyester compound. A heavy aluminum plate is glassed to the underside of the hull flange with unidirectional roving, reinforcing the joint loaded by the shroud lugs.

Practical Sailor judged the 25D probably one of the strongest boats of her size on the market. The same review noted that a full molded hull liner carries the major furniture components and adds stiffness below. This liner is a heavy, solid layup nearly as thick as the hull.

The rudder hangs from the back of the keel. All deck hardware is through-bolted with stainless steel bolts and aluminum backing plates, while Spartan seacocks serve every below-water through-hull. Teak toerails, rubbing strake, cabintop handrails, and cockpit coamings soften the otherwise glass-and-bronze structure. Gelcoat quality is excellent.

Rig and Handling

The 25D’s rig is substantially more modern than the 25’s. Its mast is 4½ feet taller, the J measurement is more than a foot longer, and the mainsail has a higher aspect ratio. Jiffy reefing is standard.

Although the mast was originally drawn to step through to the keel, the production mast is deck-stepped. An aluminum compression column directly beneath it transfers rig loads to the keel. The shrouds attach to cast bronze lugs that rest on the deck over the hull/deck flange. Each lug is fastened with two 3/8-inch stainless machine screws. This is an immensely strong installation for a boat of 5,000 pounds displacement and is less prone to leakage than conventional bulkhead-mounted flat-bar chainplates.

A recessed inboard jib track complements the rail-mounted genoa track. A full-width mainsheet traveler spans the aft end of the cockpit.

Changes below the waterline matter as much as the taller rig. Compared with the 25, the 25D has an additional 6 inches of draft, 9 inches of beam, hard bilges, and 350 pounds more ballast. These changes should make her quite stiff, and Practical Sailor allowed that the 25D may actually have better performance potential than the 25.

The two-bladed solid-bronze propeller sits in an aperture at the aft end of the keel that extends into the rudder. This arrangement tucks the gear securely out of the way, though cross-ventilation through the aperture costs a little rudder efficiency under sail.

Power and Systems

The 25D’s inboard is a raw-water-cooled Yanmar 1QM diesel producing 7½ horsepower. At 154 pounds, it was one of the lightest small diesels available. It turns a 2.62:1 reduction gear through a conventional installation that met ABYC standards.

A 13-gallon fuel tank beneath the cockpit provides roughly 250 miles of powered range. The 20-gallon polyethylene water tank is under the starboard quarterberth, which the review called the best berth aboard. The galley has a recessed two-burner Kenyon alcohol stove with an integral tank.

Accommodations

The 25D has an unusual interior for a boat of this size. Instead of a forward cabin, it has a large head with room for a shower. The compartment provides 5′9″ of headroom, two hanging lockers, a small sink, and solid towel-rack grab rails. A Bomar hatch and two opening ports provide ventilation.

Dropping the cabin sole into the bilge creates honest main-cabin headroom of about 5′11″. Ash, rather than teak, lines the hull outboard of the settees. The settee backs are properly angled and padded, and the starboard settee can be extended into a double with some maneuvering. Altogether, the boat nominally sleeps four.

Four opening bronze ports provide excellent cross-ventilation in the main cabin. The settees continue through the head bulkhead to form dresser alcoves. Stowage includes a shallow locker to starboard above the quarterberth and a deep locker to port; the port locker also provides access to the stuffing box.

Known Issues

Bilge access is limited to a small trap in the main-cabin sole, restricting both inspection and pumping reach. If the optional shower is installed, it drains directly into the bilge—an arrangement the review found wanting.

The propeller aperture’s intrusion into the rudder slightly reduces rudder efficiency under sail. A few 25Ds were delivered with pedestal steering. Although it frees up cockpit seating, the pedestal looks oversized for the boat.

The Verdict

The Cape Dory 25D is a deliberate pocket cruiser: heavily built, stiff, and laid out for a couple to live aboard and venture offshore. Its rig and underbody reach beyond the earlier 25’s more modest ambitions. It isn’t a racer, but its disciplined construction and genuine cruising layout make it a durable small yacht.

Pros

  • Immensely strong chainplate and hull-flange structure for her size
  • Lead ballast encapsulated in a hollow keel molding with slurry fill
  • Genuine cruising interior with a large head and honest headroom
  • Stiff hull with more beam, draft, and ballast than the 25
  • Inboard diesel with a securely tucked, aperture-mounted bronze propeller

Cons

  • Bilge access limited to a small trap in the cabin sole
  • Optional shower drains into the bilge
  • Propeller aperture slightly reduces rudder efficiency
