Design and Construction
At 31.3 feet overall, the Grand Surprise has a 29.3-foot waterline, a 9.78-foot beam, and a 6.73-foot draft. Displacement is 5,842 lb, including 2,315 lb of lead ballast. That gives a ballast-displacement ratio of 39.6 percent—near 40 percent—which keeps the boat stiff without burdening the hull.
Archambault built both the hull and deck in solid fiberglass-polyester. The deep lead bulb keel gives the boat quick acceleration and efficient upwind tracking. Countersunk thru-hull fittings help keep the underwater profile clean. This example also has two hatches to storage rooms, where the standard boat has only one.
A capsize screening value of 2.17, together with the ballast-displacement ratio, places the Grand Surprise at the lively, seaworthy end of the performance-cruiser spectrum rather than in the ponderous cruising mainstream.
Rig and Handling
The fractional sloop rig includes a retractable bowsprit and has benefited from several rounds of renewed rigging. Dyform stays and a Spectra backstay were fitted in 2011. Dyneema racing halyards and sheets followed in 2017, alongside replaced deck hardware.
Harken tufluf genoa inhaulers allow the headsail to be pulled close to the centerline for tight-angle reaching. An aluminum spinnaker pole complements the bowsprit, giving the crew options for asymmetric or conventional kite work. Four Lewmar self-tailing winches and a Spinlock tiller extension keep the controls within reach of the helm.
The 544-square-foot sail plan drives a hull-speed calculation of 7.25 knots.
Accommodations
Below, the Grand Surprise is a functional cruiser-racer rather than a floating apartment. A vacuum Lavac marine head is paired with a 40-liter drain tank. One 100-liter flexible water tank supplies the galley, which has a two-burner gas cooker and a separate 5-liter gas tank.
A Waeco compressor refrigerator is noted as new, while Ebensprächer D2 electronic diesel heating extends the sailing season. LED interior lighting reduces electrical demand, and a folding table can also be used in the cockpit. The comfort ratio of 14.48 reflects a boat designed to sail first and entertain second.
Engine, Electrical System, and Refit History
This 2005 hull comes with a disciplined refit history. The standing rigging was changed to Dyform in 2011, while Dyneema racing running rigging and replacement deck hardware were added in 2017. In 2019, the hull was fully stripped, refaired with new epoxy, and finished with Hempel silicone antifouling.
The original 2005 Nanni 2.50 diesel produces 14 hp and had logged roughly 600 hours. It turns a two-bladed folding propeller through a single shaft. The 35-liter fuel tank is fitted with a Racor filter.
The electrical system includes two batteries from 2020, a Mosfet splitter, and a Quick 2x12 amp charger with a NASA monitor.
The Verdict
The Grand Surprise is a crisp, well-documented example of a modern French performance cruiser. She’s light on her feet, stiff to windward, and backed by a refit record that removes much of the guesswork. She best suits sailors who want to cover ground quickly and are content to live simply aboard.
Pros
- Deep lead bulb keel supports quick acceleration and efficient upwind performance
- Thorough rig and hull refit history through 2019
- Solid-GRP construction, countersunk thru-hulls, and an extra storage hatch
Cons
- Modest 7-gallon fuel and 26-gallon water capacities limit extended off-grid cruising
- Two-burner galley and non-CE gas installation are basic for longer stays
