Design and Construction
Gibert Marine built the Gib'Sea 116 as a solid fiberglass hull with fin keel and skeg rudder, reflecting the yard's typical 1980s construction below the waterline. Her 6,200 pounds of lead ballast and 12.5-foot beam give a stable, predictable platform; the displacement-to-length ratio of about 232 marks her as a moderate cruiser rather than a spartan racer, and the comfort ratio of 25.8 is consistent with a boat meant for extended coastal and offshore passage work. The capsize screening value of 1.97 sits where you would expect for a 40-foot family cruiser — outside the extreme-survival envelope but well within normal recreational bounds. A shoal-keel version was offered, drawing just over five feet and carrying slightly more displacement and ballast than the standard fin, a useful alternative for shallow-water cruising grounds.
Rig and Handling
The Gib'Sea 116 is a masthead sloop carrying about 592 square feet of sail area, which against her displacement yields a sail-area-to-displacement ratio of 14.6 — enough to keep her moving in modest breeze without demanding a heavy crew. Her hull speed calculates to 7.54 knots, and the S# value of 2.1 places her performance squarely in the moderate cruiser category rather than the lively sportboat end. The skeg-hung rudder behind a fin keel gives good steering authority and protection against grounding damage, a sensible choice for a boat many of which went straight into the charter trade.
Accommodations
The standard Gib'Sea 116 was laid out as a cruising interior, but a MASTER or owner's version was also available for private buyers who wanted a different berth and stowage arrangement than the charter-spec boats. Many of the class were sold directly to the charter trade, which means a significant share of surviving examples will show the wear patterns and simplified systems of commercial service rather than careful private ownership. The 100-gallon water capacity and 41-gallon fuel capacity are generous for a 40-footer of this era and support extended cruising without constant reprovisioning.
Refits and Ownership
Because so many Gib'Sea 116s began life as charter boats, prospective owners should expect that any given example may have seen hard use in its early years before passing to private hands. The Volvo Penta diesel of 50 horsepower is a straightforward and well-supported installation, and the solid hull construction means there is no cored laminate below the waterline to trap moisture. The shoal-keel variant in particular may appeal to owners who prioritize gunkholing over absolute windward performance.
The Verdict
The Gib'Sea 116 is a thoughtfully proportioned moderate-displacement cruiser from the last independent decade of Gibert Marine, with a practical Joubert-Nivelt hull, sensible rig numbers, and a roomy interior backed by serious tankage. The heavy charter presence is the one caveat: many boats will need careful inspection for early-life abuse, but a well-kept example rewards its owner with a stable, capable 40-foot cruiser.
Pros
- Moderate 37.6 percent ballast ratio with lead keel for predictable stability
- Generous 100-gallon water and 41-gallon fuel capacity for a 40-footer
- Skeg-hung rudder protects steering gear behind the fin keel
- Owner's-version layout available alongside standard charter layout
Cons
- Many examples began in charter service and may show corresponding wear
- Single 1984 model year limits parts/commonality across a production run
