About the G-CAT 5.0
The G-Cat 5.0 is a lightweight, high-performance catamaran designed by Hans Geissler and built by G-Cat (USA) in 1975. With a displacement of 340.0 lb and a beam of 8.0 ft, this vessel represents an early example of recreational multihull design, though the exact number of hulls built remains unknown.
- Best for:
- This boat is best suited for coastal day-sailing and light cruising in protected waters, appealing to sailors who prioritize speed and ease of handling over heavy offshore capability.
- Bluewater capability:
- With a very low displacement of 340.0 lb and a comfort ratio of 2.08, the G-Cat 5.0 is not designed for bluewater cruising and is limited to coastal and sheltered water sailing.
- Comparables:
- Comparable vessels include other early 1970s recreational catamarans such as the Microcat or early Hobie Cat models, which share similar fractional sloop rigs and lightweight construction aimed at casual weekend use.
