Design and Construction
Briand’s hull has a 28-foot 10-inch waterline and an 11-foot 11-inch beam, giving a length-to-beam ratio of 2.81. It’s a relatively beamy design that favors volume over outright speed.
The Espace 1000 displaces 12,787 pounds and carries 4,564 pounds of iron ballast, for a ballast ratio of 38 percent. Its displacement-length ratio of 237 places it firmly in the loaded-cruiser camp, rather than among light racers. A capsize screening value of 2.02 and a Motion Comfort Ratio of 24.3 describe a stable hull with easy motion rather than a lightweight racer.
Wetted surface is about 409 square feet. An immersion rate of 1,188 pounds per inch indicates how gradually the boat settles as provisions and cruising gear come aboard. Construction is straightforward for a production boat of the period: a hand-laid fiberglass hull beneath a sandwich-construction fiberglass deck.
Keel Options and Draft
The choice of keel affects where the Espace 1000 can cruise. The stub-centerboard version draws just 4 feet 0 inches to 4 feet 4 inches, depending on load, allowing access to even shallow marinas.
The fin-keel version draws 5 feet 5 inches to 5 feet 9 inches. That’s suitable for most marinas, though not the shallowest. Both keels are iron, so their grounding behavior and antifouling requirements differ from those of lead keels, but the structural arrangement is simple and robust.
Rig and Sail Plan
The masthead rig carries 473.6 square feet of mainsail and jib. The running-rigging guide specifies 33.1-foot jib and genoa sheets at half-inch diameter, an 82.8-foot mainsheet of the same diameter, and 72.9-foot spinnaker sheets.
The theoretical hull speed is 7.2 knots, a natural ceiling for a displacement hull of this waterline length. Its sail-area-to-displacement character suits a comfortable cruising tempo rather than planing performance.
Engine, Fuel, and Water
Jeanneau offered two inboard diesel alternatives, both driving through a shaft. The 40 hp version has a calculated maximum speed of about 7.1 knots, while the 60 hp version reaches a calculated maximum of about 8.7 knots. Both figures are close to the boat’s 7.2-knot displacement hull-speed limit, so the extra horsepower provides more thrust margin rather than much additional speed.
A 52-gallon stainless-steel fuel tank supports the diesel installation. Fresh-water capacity is 66 gallons.
Accommodations
The deck-saloon arrangement provides a sheltered interior, with some loss of cockpit intimacy. Below, the Espace 1000 has six berths, a galley, and a toilet facility. The interior is finished in mahogany, as were many production cruisers of the period.
The production run totaled 228 boats, and spare parts and peer knowledge are reasonably findable among the French and northern-European fleets.
Verdict
The Espace 1000 is a pragmatic early-1980s deck-saloon cruiser: beamy, stable, and available in a shallow-draft centerboard version that opens tidal and shallow marinas most 35-footers can’t reach. Construction is conventional hand-laid fiberglass with iron ballast, and the rig is a workmanlike masthead sloop. The two diesel options give buyers a clear choice between adequate and generous auxiliary power.
Pros
- Shallow 4-foot centerboard draft improves marina access
- Stable, comfortable motion, with a Motion Comfort Ratio of 24.3 and a capsize screening value of 2.02
- Mahogany interior with six berths, a full galley, and a toilet facility
- Choice of 40 hp or 60 hp shaft-drive diesel
Cons
- Iron keel and ballast require vigilant antifouling and monitoring for corrosion
- A displacement-length ratio of 237 confirms that she’s a heavy cruiser, not a light airliner
- Fin-keel draft of 5 feet 5 inches to 5 feet 9 inches limits access to the shallowest anchorages
