Operational history

In a 2010 review Steve Henkel wrote, "best features: She is fast and easy to sail. A 46% B/D ratio, with a bulb keel concentrating her ballast low, gives her good stability. An outboard well located in the cockpit keeps the engine under the helmsman’s control. And for those looking for camaraderie, the big network of Cal 20 fleets (largely on the West Coast) will be attractive. Worst features: Fin keel with bulb makes the boat a chore to launch at shallow ramps. Also, the boats are among the oldest fiberglass boats around, and most will require more strenuous than ordinary maintenance to keep in top condition. The keel (made of iron, which rusts), keel bolts, and surrounding fiberglass are common causes of concern."Henkel, Steve: ''The Sailor's Book of Small Cruising Sailboats'', page 89.
