Design and Construction
Gibert Marine built both the hull and deck in solid fiberglass. The keel is iron rather than lead, with 6,850 pounds of ballast and a ballast ratio of 34 percent. That ratio is higher than those of 21 percent of comparable sailboat designs, and the 6,850-pound ballast contributes to the boat's settled, deliberate character.
The hull has a length-to-beam ratio of 3.11, reflecting the designer's choice of a slightly more voluminous form. Compared with similar sailboats, the 126 is roomier than 73 percent of all other designs.
Wetted surface is about 484 square feet, while the immersion rate is approximately 1,565 pounds per inch. In practical terms, she sits heavily and changes trim slowly as weight is added.
Rig and Handling
The 126 has a conventional masthead-sloop rig. Estimated jib and genoa sheet lengths are about 41 feet, using 14 mm line. The mainsheet is a much longer 103-foot run, also using 14 mm line, while the estimated spinnaker sheet length is about 91 feet. These are estimator figures, but they describe a boat sized for serious offshore canvas rather than day-sailing shorthand.
Theoretical hull speed is 7.8 knots, consistent with the boat's displacement and 33.8-foot waterline. Her fin keel draws roughly 5.9 to 6.2 feet, depending on load. That draft restricts her to major marinas and keeps her out of shallow anchorages.
Accommodations
Breadth and hull volume define the 126's accommodations. With a 13.3-foot beam and a hull form explicitly chosen for roominess, she offers living quarters that outclass most contemporaries of similar length.
The combination of a 33.8-foot waterline and a 3.11 length-to-beam ratio gave Joubert-Nivelt a generous platform for a cruising interior with genuine room to stretch out.
Verdict
The Gib'Sea 126 Croisiere is a heavy, roomy, solidly built French cruiser from the early 1980s. She prioritizes volume and stable load carrying over sparkling performance. Her iron keel, deep draft, and high immersion rate suit long-distance cruising where marina depth isn't a constraint.
She will appeal most to buyers who value interior space and a proven displacement hull more than shoal draft or racer-like acceleration.
Pros
- Roomy hull—more spacious than 73 percent of similar designs
- Solid-fiberglass hull and deck construction
- High 34 percent ballast ratio for stability
- Conventional, well-understood masthead-sloop rig
Cons
- Deep draft limits her to major marinas
- High immersion rate means slow changes in trim under load
- Iron keel rather than lead
