Design and Construction
Alberg’s hand shows in the full keel and attached rudder, which let the 33 track well both on and off the wind, and in the substantial overhangs that give her the profile of his cruisers. The hull itself is a solid laminate of plastic resin and fiberglass cloth, and the laminate thickness runs greater than average for a production sailboat in this size range — a deliberate heft that pairs with the 5,500 pounds of lead ballast and the 41-percent ballast-displacement ratio to explain the boat’s composure once loaded. Structurally, the hull is supported by fiberglass-encapsulated members, full and partial transverse bulkheads, and molded fiberglass liners, with attachments and secondary bonding generally sound. Decks are a different matter in composition: a composite of fiberglass, resin, and balsa wood core, a construction that serves weight and stiffness but introduces a vulnerability the solid hull does not have.
Rig and Handling
The 33 was offered with either a sloop or a cutter rig, and the choice is consequential. The cutter carries real advantages in heavy weather and offshore conditions, while the sloop, carrying a large genoa, is the better performer on the Chesapeake. Either way she shows her true heritage in moderate to heavy air: initially a little tender, she firms up nicely at about 15 degrees of heel and from there behaves like the steady Alberg cruiser she is. The full-keel tracking is a virtue in a seaway and under autopilot, though the same overhangs that grace her lines mean excessive weight in the ends will blunt her performance — a point worth remembering when loading anchors and ground tackle.
Accommodations
Below, the 33 follows a conventional Alberg sequence: a forward berth, then a port-side head and starboard lockers, then the main saloon with opposing settees, a starboard navigation station, a quarter berth, and a port galley. The forward berth is an L-shaped single that can be extended into a double with some effort, a layout the reviewing sailor noted he would rather have seen executed as a standard V. The later 330 corrected that, gaining a true V-berth cabin forward followed by a starboard head with shower, and in the saloon the settees were pushed further outboard for a more open feel with a large galley spanning the after cabin. The 33’s interior is functional and traditional rather than expansive, but the volume reads as honest cruising accommodation.
Known Issues
The balsa-cored deck is the boat’s weak point as she ages. Moisture saturation of the core and delamination are not uncommon, especially along the side decks near the chain plates and rigging attachments. Compounding the inspection difficulty, Cape Dory used a mild steel bracket for the lower-shroud chain plates, and that bracket is subject to considerable corrosion and wasting if leaks persist — yet those chain-plate areas are hard to inspect because of the installed fiberglass hull liners, so careful attention is required to head off serious problems. Beyond the decks, aging 33s commonly show water saturation and delamination of the rudders along with moderate osmotic blistering on the hull.
Refits and Ownership
Power came from either a 23-horsepower Volvo or a 24-horsepower Universal marine diesel depending on the year, and parts and service remain readily available for either; properly maintained, each is capable of several thousand hours of dependable running. The modest 21-gallon fuel and 74-gallon water capacities suit coastal cruising rather than long self-sufficient passages, and the solid-hull construction means a buyer’s refit energy is better spent on deck-core remediation and chain-plate access than on structural hull work.
The Verdict
The Cape Dory 33 is a quintessential Alberg cruiser: heavy, steady, and reassuring in a blow, with a build substance in the hull that few contemporaries matched. She asks her owner to respect the balsa deck and the hidden mild-steel chain-plate brackets, but in return gives a tracking, forgiving platform that rewards traditional cruising instincts.
Pros
- Solid fiberglass hull laminate thicker than average for the size
- Full keel and attached rudder track well on and off the wind
- Readily available engine parts for both Volvo and Universal diesels
- Composed, firm handling past 15 degrees of heel
Cons
- Balsa-cored decks prone to moisture and delamination near chain plates
- Mild-steel lower chain-plate brackets corrode if leaks persist, and are hard to inspect
- Rudder saturation, delamination, and moderate osmotic blistering as she ages
- Conservative 15.6 sail-area-displacement ratio limits light-air pace
