Design and Construction
The 302 is a solid-fiberglass monohull with a fiberglass deck, built by the French yard Gibert Marine anchor. At a length overall of just under 30 feet with an 11-foot beam, the design carries a length-to-beam ratio of 2.67 and a ballast ratio of 35 percent, the latter built around 2,400 pounds of iron ballast in a 7,060-pound displacement. The wetted surface is about 312 square feet, and the immersion rate of roughly 1,136 pounds per inch speaks to a hull that sits with moderate reserve but responds visibly to load.
Keel Options and Draft Profile
One of the 302's defining traits is its multiple keel alternatives, all iron. A drop-keel version draws only about 2.3 to 2.6 feet depending on load, letting the boat into shallow marinas anchor, while two fin-keel variants bracket it: one at roughly 6.0 to 6.3 feet that limits the boat to major marinas, and a shallower fin at about 5.4 to 5.7 feet that suits most marinas anchor. The spread of draft choices means a used buyer can select for either gunkholing or windward bite without leaving the same mold line.
Rig and Sail Plan
The 302 is a masthead sloop, and the rig is its most unusual attribute: the boat carries more sail rig than 90 percent of comparable sailboats, which the review describes as significantly overrigged anchor. That excess shows up in the running rigging dimensions as much as the sail area. Halyards for the mainsail, jib or genoa, and spinnaker each run 93.8 feet at 5/16 inch, while sheets scale up to 3/8 inch, with the mainsheet at 73.7 feet and the spinnaker sheets at 64.9 feet. A cunningham and kicking strap of 12.8 and 25.5 feet respectively, plus a 25.5-foot clew outhaul, round out a control suite sized for a boat that expects to fly a lot of canvas. The masthead rig and tall mast—about 46 feet above the waterline—reinforce the sense of a small hull carrying a large sail plan.
Accommodations and Layout
The available review does not describe the interior arrangement in detail, so the accommodations must be framed by what is known: a 29-foot hull with an 11-foot beam and 47 gallons of water against 16 gallons of diesel, a single 18-horsepower Yanmar diesel, and a masthead rig tuned for power. The proportions suggest a compact cruiser oriented toward short-handed sailing rather than charter-scale volume, and the keel choices imply an owner who weighed draft against mooring access.
The Verdict
The Gib'Sea 302 is a small French cruiser with a distinct personality: a modest-production Joubert-Nivelt design whose overrigged masthead rig outclasses most peers its size, paired with a keel program that lets the same boat chase shallow creeks or stand up to a breeze on a deeper fin. The construction is straightforward solid glass from the Gibert Marine era of the early 1990s, and the numbers describe a boat that rewards an owner who values rig power and draft flexibility over interior square footage.
Pros
- Three iron keel options including a shallow drop keel for marina access
- Significantly overrigged masthead rig for a 29-foot hull
- Solid fiberglass hull and deck from period Gibert Marine practice
Cons
- Deep fin-keel version limited to major marinas by 6-foot-plus draft
- Modest production run limits broad used-market familiarity
- Accommodation detail not documented in available review material
