About the MARSHALL 22 CAT
A sloop rigged version was also available. See MARSHALL 22 SLOOP.
The Marshall 22 Cat is a rare, single-year production catamaran designed by Breckenridge Marshall and built by The Marshall Company in 1965. With an unknown total build count, this vessel represents a unique snapshot of early American multihull design, featuring a 22.18 ft LOA and a distinctive gaff rig.
- Best for:
- This boat suits adventurous cruisers seeking a lightweight, trailerable multihull for coastal exploration or those interested in preserving a historic piece of sailing heritage. Its shallow draft and manageable size make it ideal for owners with limited storage space who prioritize ease of handling over heavy offshore endurance.
- Bluewater capability:
- With a displacement of 5660.0 lb and a capsize ratio of 2.29, the Marshall 22 Cat is primarily suited for protected coastal waters rather than extended bluewater passages. Its light ballast of 850.1 lb and narrow beam relative to its length suggest it requires careful handling in heavy weather.
- Comparables:
- Comparable vessels include other early 1960s experimental catamarans and small trimarans from the same era, such as the Hobie Cat or early Pacific Seacraft designs, due to their shared role as pioneers in recreational multihull sailing. They are similar in their focus on light displacement and ease of single-handed operation.
