Design and Construction
The 522 has a solid fiberglass hull and deck, consistent with Gibert Marine's typical 1980s laminate practice. She was offered with different keel alternatives—both a fin and a shallow iron keel.
The fin-keel version draws about 8.5 to 8.8 feet, depending on load. Even the shallow keel draws 6.6 to 6.9 feet, so either configuration restricts the boat to major marinas.
Her proportions reflect her cruising purpose. She has a length-to-beam ratio of 3.39, a 33 percent ballast ratio based on 11,000 pounds of lead, and a displacement-length ratio near 195. These figures mark her as a heavy, volume-oriented offshore hull rather than a light racer. A capsize screening value of 1.88 and a Motion Comfort Ratio of 30.4 place her firmly in the stable-passage-candidate bracket.
Rig, Performance, and Handling
The 522 carries a cutter rig. Her reference sail area produces a sail-area-to-displacement ratio of 18.9, rising to 22.6 with a 135 percent genoa—modest but workable for a 33,000-pound hull.
Wetted surface is about 753 square feet. An immersion rate of roughly 2,226 pounds per inch means she sits heavily and resists heel-driven changes in trim. Her theoretical hull speed is 8.7 knots, the natural limit for a displacement hull of this length. Owners planning passages should regard that as the practical ceiling under power or sail.
The standing and running rigging dimensions are substantial. The mainsheet alone is 128 feet of 5/8-inch line. Halyards are 155 feet long and 14 mm in diameter, while the jib and genoa sheets are 51 feet of 5/8-inch line. Those lengths and diameters suit a big-boat cockpit, where mechanical advantage and durability matter more than featherweight speed.
Tankage and Power
The 522 carries 343 US gallons of fresh water, a serious provision for extended cruising that underlines her passage-making intent rather than weekend use. A 132-gallon diesel tank and an 80-horsepower Perkins single further support long, autonomous stretches.
Verdict
The Gib'Sea 522 is a heavy, comfortable, solidly built 1980s cruiser from a respected French design partnership. She suits sailors who value tankage, stability, and the versatility of a cutter rig more than shallow draft or light-air acceleration. Her iron keel options keep her to deep-water ports.
Pros
- Solid fiberglass hull and deck from Gibert Marine's 1980s construction era
- High ballast ratio and capsize screening suited to offshore passage-making
- Generous 343-gallon water and 132-gallon fuel capacity for autonomy
- Cutter rig with strong sail-area potential under genoa
Cons
- Deep draft, even with the shallow-keel version, limits marina access
- Heavy displacement and substantial wetted surface blunt light-air performance
- Iron keels rather than lead invite corrosion vigilance
