Notes

S&S design #1710.31
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.
Originally designed to the RORC handicap rule, the rig was changed in order to rate more favorably under the newly adopted IOR.
This was the first 'Swan'. Ole Enderlein was hired (by Nautor) to design a new interior.
