S&S design #1710.31
The SWAN 36 sold by Palmer Johnson.
In turn, based on the GAIA CLASS (1965, 19 were built by Benello of Italy.)
There were a number of other variants of this particular design including the SIGMA 36 by Cheoy Lee.
This was the first 'Swan'. Ole Enderlein was hired (by Nautor) to design a new interior.
Originally designed to the RORC handicap rule, the rig was changed in order to rate more favorably under the newly adopted IOR.
