About the GIB'SEA 84
Also available with twin keel, tri keel, or keel/cb.
Designed by Joubert-Nivelt and built by Gilbert Marine, the Gib'Sea 84 is a compact, heavy-displacement cruiser produced from 1982–1988 with a total build count of 250 hulls. Its substantial displacement of 6172.0 lb and low capsize ratio of 2.18 reflect a design philosophy prioritizing stability and seakeeping over pure speed.
- Best for:
- This boat is ideally suited for coastal cruising and short offshore passages where comfort and stability are prioritized over high-performance racing. Its manageable LOA of 27.75 ft and robust construction make it a practical choice for couples or small families seeking a reliable, easy-to-handle package.
- Bluewater capability:
- With a displacement of 6172.0 lb and a capsize ratio of 2.18, the Gib'Sea 84 is well-suited for protected coastal and nearshore bluewater cruising, offering excellent stability and motion comfort, though its moderate SA/D ratio of 15.98 suggests it is not designed for high-performance offshore racing.
- Comparables:
- Comparable vessels include the Tartan 27 and O'Day 27, which share similar dimensions and a focus on safe, stable cruising. Like the Gib'Sea 84, these boats offer a comfortable interior and manageable sail plan, though the Gib'Sea distinguishes itself with a heavier displacement and distinct Joubert-Nivelt hull form.
