About the GIB'SEA 20
The Gib'Sea 20 is a compact, trailerable sloop designed by M. Joubert and built by Gilbert Marine between 1975 and 1980, with a total production of 260 hulls. Its lightweight displacement of 2315.0 lb and fin keel configuration reflect a design philosophy focused on ease of handling and transportability rather than heavy offshore cruising.
- Best for:
- This boat is ideally suited for coastal cruising, weekend getaways, and trailerable sailing, appealing to owners who prioritize easy storage and transport over long-range bluewater capabilities.
- Bluewater capability:
- With a low displacement of 2315.0 lb and a comfort ratio of 14.12, the Gib'Sea 20 is not designed for serious offshore passage-making and is best restricted to protected coastal waters.
- Comparables:
- Comparable vessels include other trailerable sloops from the 1970s such as the O'Day 23 or Catalina 22, which share similar dimensions and roles, though the Gib'Sea 20 distinguishes itself with a lighter displacement and specific Joubert design lines.
