Design and Construction
Built in France, the Challenger Bravo is a solid-fiberglass monohull with a fin keel. The manufacturer rated the boat as unsinkable.
The Challenger Bravo (sans jupe) measures 7.90 meters overall with a beam of 2.95 meters, according to the manufacturer. A later technical review gives a hull length of 7.70 meters and a beam of 2.90 meters; both sets of figures describe the same cruising-sailboat program.
Displacement is listed at about 1,820 to 1,900 kg, with 1,543 lbs of lead ballast. That produces a ballast ratio near 38 percent—higher than 42 percent of similar designs, but still associated with below-average resistance to heeling. A length-to-beam ratio of 2.76 and wetted surface near 24 square meters reinforce the picture of a roomy, moderate-draft coastal cruiser rather than a slender racer.
Rig and Handling
The Bravo carries a masthead sloop rig with a stated sail area of 36.50 square meters. Its listed sail-area-to-displacement ratio is 22.94, a moderate figure consistent with the boat’s cruising brief rather than a lightweight planing hull.
The capsize screening value is 2.28, which would exclude the Bravo from ocean-race acceptance. Its immersion rate is about 155 kg per centimeter (870 lbs per inch), so the boat settles predictably as weight comes aboard.
Standard sheet specifications call for 10 mm line throughout:
- 8.0-meter jib and genoa sheet
- 20.0-meter mainsheet
- 17.6-meter spinnaker sheet
Depending on load, the fin keel draws roughly 1.85 to 1.95 meters. That creates a genuine shoal-water limitation despite the boat’s modest hull length.
Accommodations
The Bravo has six berths. That supports the manufacturer’s five-person homologation while leaving one spare sea berth for a child or another crew member.
Period comparisons put its interior volume above 82 percent of similar sailboats, in keeping with the beamy 2.90-meter hull form. This is first and foremost a habitable cruising design, with its volume devoted to weekending and short coastal passages rather than offshore self-sufficiency.
Design Limits and Known Issues
The main cautions lie in the Bravo’s design numbers. Its ballast ratio is associated with below-average resistance to heeling, so it will heel earlier than a more heavily ballasted contemporary. The capsize screening value of 2.28 also confirms that the boat wasn’t conceived for ocean racing.
These are design limits rather than faults. The hull itself carries an unsinkable rating, and its construction is straightforward solid fiberglass.
Refits and Ownership
The Bravo may be fitted with an inboard engine, although no specific make or horsepower is named. Since production ended in 1984, any surviving example is a candidate for age-related systems work. The engine, wiring, and standing rigging should therefore be judged by their present condition rather than their original specifications.
The simple fiberglass hull and fin keel make a structural survey straightforward. The unsinkable certification also reduces concern over minor penetrations if they’re properly repaired.
The Verdict
The Challenger Bravo is a compact, beamy French cruiser with more interior space than its length might suggest and a genuine manufacturer-issued unsinkable rating. It’s a sensible coastal and second-category cruiser, not a racer or ocean passagemaker. Gaubert’s design is clear about its limits, while the solid-fiberglass construction keeps ownership relatively easy to understand.
Pros
- Beamy hull with more interior volume than most similar designs
- Manufacturer-rated unsinkable, solid-fiberglass construction
- Predictable immersion and a moderate sail plan suited to relaxed cruising
Cons
- Below-average heeling resistance associated with a 38 percent ballast ratio
- Capsize screening value of 2.28 excludes ocean-race use
- Fin-keel draft approaching 1.95 meters limits access to very shoal anchorages
