Design and Construction
Briand's Espace 800 carries a fiberglass hull with a solid lay-up and a centerboard keel that pivots, letting the boat run both open coast and shallow inland channels. The standard keel draught is 1.85 meters, yet with the board up the draft falls to roughly 3.22 to 3.52 feet depending on load, so it can tuck into marinas a fixed-keel boat of its length could never reach. At 3,500 kg displacement with a 34% ballast ratio, the design is lumped among "ultra heavy cruisers" by displacement-length metrics — only 3% of comparable sailboats are heavier, and its ballast share exceeds just 24% of similar designs. The length-beam ratio of 2.67 makes it roomier than 90% of its peers, a figure that explains the generous footprint below.
Rig and Handling
The boat is a fractional sloop carrying 430 square feet of sail area, returning a sail-area-displacement ratio of 17.62 — modest, consistent with the heavy-cruiser character. A wetted surface near 247 square feet and an immersion rate of about 703 pounds per inch speak to a voluminous hull that sits deep. Period manufacturer description holds that the hull form and deck fittings preserve true sailboat traits, promising speed and a fine touch in seas. The capsize screening value is 1.99, and the theoretical hull speed is 6.1 knots. Sheet specs are practical: mainsheet runs 65.6 feet, jib and genoa sheets 26.2 feet, spinnaker sheet 57.7 feet, all 3/8 inch diameter.
Accommodations and Cockpit
Jeanneau presented the Espace 800 as offering piloting at the engine in a totally new way, with comfort measures not previously seen on a sailboat hull. The cockpit gives maximum comfort, and the boat is rated for five to seven people. Fresh water capacity is 95 liters (25 US gallons), with fuel at 110 liters — figures that support extended weekends. The Motion Comfort Ratio of 25.3 places it ahead of 82% of similar designs for ride quality, a meaningful data point for a couple or small family cruising.
Known Issues
The only documented maintenance caveat is structural to the centerboard: keels with moving parts require regular inspection and upkeep per the owner's manual. A buyer or owner should treat the pivot gear as a scheduled-service item rather than a fit-and-forget system.
The Verdict
The Espace 800 is a distinctive early-eighties motor-sailer that trades outright sailing performance for versatility and volume. Briand gave it a beamy, heavy hull with a lifting keel that opens both coastal and inland cruising, and Jeanneau wrapped the package in a cockpit conceived around motoring comfort. For the sailor who wants one compact boat to do slack-water rivers and offshore bays, it remains a thoughtful answer.
Pros
- Pivoting centerboard permits coastal and inland-water sailing with 3.2-foot minimum draft
- Roomier than 90% of comparable designs, with comfort ratio exceeding 82% of similar boats
- Generator-class fuel and water capacity for its size (110 L fuel, 95 L water)
Cons
- Ultra-heavy displacement and low SA/D (17.62) limit light-air sailing spark
- Centerboard pivot demands recurring inspection and maintenance
