Design and Construction
At 16,100 pounds displacement with a 27-foot waterline that is just 75 percent of the 36-foot overall length and 9 feet of overhangs, the Cape Dory 36 carries the long, narrow proportions Alberg favored. The hull is hand-laid in a rotating, one-piece mold with alternating layers of fiberglass mat and woven roving, while the deck is balsa cored except in areas of high load and stress where it is solid glass, plywood, or aluminum. The hull-and-deck joint sits on a wide 3-inch inward flange and is through-bolted on 12-inch centers, and separate molds were used to lay up the headliner and the pans in the V-berth and galley. A fiberglass subfloor adds athwartships support but further limits hull access. Ballast is cast in two pieces placed inside the keel cavity, secured with several layers of fiberglass and covered with gelcoat for a smooth, clean bilge finish. The rudder combines two fiberglass half shells filled with a polyester compound and is built around a beefy 1 ½-inch stock.
Rig and Handling
The full keel is cutaway forward with an attached rudder, and the propeller is enclosed in an aperture — a protected arrangement suited to offshore work. Most Cape Dory 36s were rigged as cutters with a club boom, though a few left the factory as sloops, and most have wheel steering with a T-shaped cockpit designed to accept a pedestal and decent-sized wheel. The single-spreader mast is keel-stepped and heavily stayed. With an SA/D of 15.7 and a displacement-length ratio of 356, the boat is not fast, but it tracks well and resists pounding in a seaway, and heaves-to very well, a quality bluewater sailors find reassuring.
Accommodations
The interior reflects the narrow beam rather than fighting it: although 6-foot, 4-inch headroom helps, the saloon reads as distinctly narrow. The cutter rig with its original staysail on a club boom defined the forward working area, and many boats have since refit the staysail with furling gear. The standard auxiliary was the old reliable Perkins 4-108 4-cylinder 50-horsepower diesel, paired with a fiberglass fuel tank, though some owners have retrofitted an aluminum tank.
Known Issues
On hulls before No. 71, a mild steel web attached the lower shrouds and the backstay to the hull, and that unusual bracket was prone to trouble; after hull No. 71 an aluminum angle bar was fiberglassed to the hull just below the deck flange, with chainplate tangs bolted to this weldment so rig loads distributed evenly and corrosion was slower. Some owners have had problems with the rudder delaminating, a point worth weighing on any early or hard-used example.
Refits and Ownership
The staysail club boom is the most common period refit, swapped for furling gear on many boats. The fuel system is another owner-touched area, with aluminum tanks replacing the original fiberglass on some hulls. The Robinhood 36 continuation means a small number of semi-custom sisters exist, but the Cape Dory-built fleet of 165 is the body of boats most owners will meet.
The Verdict
The Cape Dory 36 is a deliberate bluewater cutter that trades speed and interior volume for seakindly tracking, a protected prop, and a thoroughly conventional Alberg hull structure. Its weaknesses are concentrated in early-chainplate corrosion and potential rudder delamination, both addressable with survey diligence.
Pros
- Proven offshore record with circumnavigations logged
- Hand-laid solid hull with robust through-bolted deck joint
- Enclosed prop and cutaway full keel for protected maneuvering
- Excellent heaving-to behavior in heavy weather
Cons
- Narrow saloon limits livable beam
- Mild steel web chainplate attachment on early hulls below No. 71
- Rudder delamination reported by some owners
- Low SA/D and high D/L mean modest light-air performance
