Gibert Marine
Gib'sea 84
Fin keel

The Gib'Sea 84 is a small cruising sailboat well thought out. She offers 2 separate cabins and a beautiful saloon where you can really eat at 6 or sleep on each side. The design is classic except the portholes in the aft coachroof that provide light and ventilation.

Light enough she goes as soon as the wind blows and aft forms, wide for the time, gives power downwind.
