Gib Sea 84
Description
The Gib'Sea 84 (also styled Gib Sea 84 or Gib'Sea 84) is a compact French family cruiser-racer designed by Joubert/Nivelt (Michel Joubert and Bernard Nivelt) and built by Gibert Marine (Gib'Sea/Gibert Marine) in France from 1983 to 1988. With moderate production (likely several hundred hulls, though exact numbers aren't widely documented), it's a fiberglass monohull masthead sloop that combines solid sailing performance with surprisingly comfortable accommodations for its sub-28 ft size—forgiving handling, good stability (often with fin keel and skeg-hung rudder for protection and tracking), and a generous sail plan for capable light-to-moderate wind performance. It's well-suited for coastal cruising, family weekends, or club use, with a practical interior: typically 2 cabins plus saloon (V-berth forward, convertible settees, compact galley, enclosed head with chemical toilet or pump-out), berths sleeping 4–5 modestly (headroom around 5 ft 9 in–6 ft / 1.75–1.83 m), and teak/practical finishes.
