I owned a new CS30 for 20 years, sold it in 2004. Berthed mostly in Alameda, we sailed San Francisco bay and the California coast from Monterey to Bodega Bay. It was great boat. I once considered sailing to Hawaii, but finally determined it did not have enough storage for food and water for a safe trip for more than one person. The only drawback I recall was that it would round-up too easy with a spinaker in a gust due to the short fin keel pitching out. The spars were seriously supported by the oversized rigging
. It sailed fast but was handicapped by PHRF so we never won any races. It could be set up for singlehandling easily. Handling was excellent in heavy or light air.
