Design and Construction
The 522 carries a solid fiberglass hull and deck, consistent with Gibert Marine's typical 1980s laminate practice, and 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 dependent on load, while the shallow keel still needs 6.6 to 6.9 feet, so either configuration limits her to major marinas. Her proportions tell the cruising story: a 3.39 length-to-beam ratio, a 33 percent ballast ratio from 11,000 pounds of lead, and a displacement-length ratio near 195 mark her as a heavy, volume-oriented offshore hull rather than a light racer. The capsize screening value of 1.88 and a Motion Comfort Ratio of 30.4 place her firmly in the stable-passage-candidate bracket.
Rig and Handling
She is built with a cutter rig and a reference sail area that yields a sail-area-to-displacement ratio of 18.9, opening to 22.6 with a 135 percent genoa — modest but workable for a 33,000-pound hull. The wetted surface runs about 753 square feet, and the immersion rate of roughly 2,226 pounds per inch means she sits heavily and resists heel-driven changes in trim. Standing and running rigging dimensions are substantial: the mainsheet alone is 128 feet of 5/8-inch line, halyards run 155 feet at 14 mm, and jib and genoa sheets are 51 feet of 5/8-inch. Those lengths and diameters suit a big-boat cockpit where mechanical advantage and durability matter more than featherweight speed.
Accommodations and Tankage
The 522 was equipped with 343 US gallons of fresh water capacity, a serious provision for extended cruising and a figure that underlines her passage intent rather than weekend sailing. Combined with a 132-gallon diesel tank and an 80-horsepower Perkins single, the boat supports long autonomous stretches. The theoretical hull speed of 8.7 knots is the natural limit of a displacement hull of this length, and owners planning passages should treat that as the practical ceiling under power or sail.
The Verdict
The Gib'Sea 522 is a heavy, comfortable, solidly built 1980s cruiser from a respected French design partnership. She rewards the sailor who values tankage, stability, and cutter-rig versatility over shallow draft or light-air acceleration, and 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 on the shallow-keel version limits marina access
- Heavy displacement and wetted surface blunt light-air performance
- Iron keels rather than lead invite corrosion vigilance
