Preliminary Design - Cygnet Class

On Tuesday we entertained about 50 members of the Sparkman & Stephens Swan Association here at our offices. It was very enjoyable to welcome such an enthusiastic group of Swan owners here to see the original plans of their boats and to see what other projects we are working on. Guests came from as far away as Finland, Sweden, Italy, England, Belgium, Australia and New Zealand.

We have obviously seen a trend in a new class of daysailers most evident in the success of the Morris Yachts M-Series. For fun we decided to go through a What if? exercise by designing a daysailer with the aesthetics of one of the favorite classic Swans, the Swan 43, design 1973. You can see the results here in these few renderings.

Here are the plans for the Swan 43.

67 boats of this model were built during this production run from 1969-1972.

Principal Dimensions Swan 43
LOA 43'-0"
LWL 31'-0"
Beam 11'-8"
Draft 7'-0"
Displacement 19,800 lbs


  1. Wasn't production 1967 - 1973? And the design is not 1973.

  2. Dear Reader,
    Interesting. The Classic Swan website shows production from 1967-1972. Our own records clearly state: "Prototype launched spring 1969."

    It is in fact S&S design #1973. You can double click and zoom in on the title blocks in the plans shown above.

  3. Dear Bruce Johnson,

    Thank you for you informative reply. I owned a Tartan 41 for many years and lived aboard for 2. I love S&S boats and hope to own another one day. Maybe the concept boat above!
