Design and Construction
The hull and deck are solid fiberglass, and the fin keel carries a lead ballast of 6,900 pounds against a 13,500-pound displacement — a 53 percent ballast ratio that, with the capsize screening value of 1.83, marks her as a stiff, seaworthy hull form. Her length-to-beam ratio of 3.09 and displacement-length ratio of 258 place her among the heavier cruiser-racer designs, while the 211 kg/cm immersion rate tells you how little she sinks for a given load. The 37-square-metre wetted surface and 6.33-to-6.63-foot draft dependent on load give her the footing of a serious keelboat.
Rig and Handling
She is built with a masthead rig carrying a 623-square-foot sail plan, and the sail-area-to-displacement ratio reads 16.6 on the ISO reference sail and 19.9 with a 135 percent genoa — figures that, alongside the note that she carries more rig than only 27 percent of similar sailboats, mark her as slightly underrigged for her type. Halyard and sheet specifications are substantial: all three halyards run 34.1 metres at 12 mm, while the 14 mm sheets — jib and genoa at 10.8 metres, mainsheet at 27.1 metres, spinnaker at 23.8 metres — speak to a deck laid out for real offshore work. The calculated maximum speed is about 5.4 knots with a theoretical displacement-hull limit of 7.3 knots, and the ride is steady and forgiving in a seaway rather than twitchy.
Accommodations
Below, the Contessa 35 provides two cabins and seven berths, with a teak interior consistent with British yachts of the period. A galley, a toilet facility, and 180 litres of fresh water capacity support extended cruising, while the 40-litre fuel tank pairs with the optionally fitted 28-horsepower Watermota Sea Panther diesel. The arrangement is compact but functional — a weekender-and-passage boat rather than a floating apartment.
Known Issues
The one quantified character point the sources establish is that she is slightly underrigged relative to peers, a performance characteristic rather than a fault. The solid fiberglass hull and deck leave few of the cored-structure failure modes that plague later boats, and the low production run of under 100 hulls means individual hull history varies more than with a mass-produced class.
Refits and Ownership
Owners fitting the optional Watermota Sea Panther diesel at 28 hp will find a modest but adequate power plant for a 13,500-pound hull. The small fuel and water tanks — 40 and 180 litres respectively — mean that cruising refit thinking should centre on capacity and stowage rather than structural renewal, and the solid-glass build means a buyer is unlikely to face cored-deck rebuilds common to many contemporaries.
The Verdict
The Contessa 35 is a thoroughly conventional Peterson-designed cruiser-racer of the mid-seventies, built in small numbers by a respected British yard in solid fiberglass with a lead-fin keel and a seakindly motion profile. She is a serious little offshore boat whose only documented shortcoming is a rig on the light side for her class.
Pros
- Stiff, seaworthy hull with 53 percent ballast ratio and 1.83 capsize screening
- Solid fiberglass hull and deck — no cored-structure failure modes
- Seven berths and two cabins with teak interior for a 35-foot boat
- Forgiving motion-comfort ratio of 26.6 to 29.9
Cons
- Slightly underrigged relative to 73 percent of similar sailboats
- Small tanks (40 L fuel, 180 L water) limit passage autonomy
- Fewer than 100 built — sparse class support and varied hull histories
