Jeff, I beg to differ on this point. The IOR boats from IIIA on (at least) had wet noodle rigs that required expertise just to keep them up - have you forgotten the "oil derrick" 3 and 4 spreader rigs from the late 70's on? The C&C design Evergreen, a two tonner built for the Canada's Cup required the onboard presence of Tim Stearn (the mast builder) just to keep the rig UP. The Santana under discussion is, I believe, the 30-30, not the 1/2 ton derived 30 from the mid 70's.
My own 1975 custom 1/4 tonner was built for the Corpus Christie Worlds in 76 and it had HYDRAULICS on the backstay & headstay as well as running backs, without which the top 1/2 of the mast would "wow" to leeward about 4 or 5 inches. When the backstay & babystay were pumped up, the rig looked like it came from a Finn!
Hardly a focus on "stiff" or "In column".
