Back in July we posted an article about Cresta IV, the prototype of the Swan 55. Cresta IV was launched in 1969. The Swan 55 was introduced the following year using the same tooling that was built for Cresta IV. The following article tells the story. Please double click for zoom. 16 boats were built to the design during a production run that lasted until 1974. Here are the plans.
