I have an oday 32 CC, which is the earlier, smaller sistership of the oday 37. It sails
very well even in fairly heavy weather
(35 kts, gusting 45). Light air performance is not as great, because it is a heavily built boat, as is the 37. Oday made very good hulls, with moderate quality interiors.
My boat has survived two hurricanes on moorings. Hurricane
Gloria in the Thames River at New London, and Hurricane
Bob in provincetown harbor. The late 70s and early 80s odays were overbuilt and very strong.
Can't comment on the CSY
Hope this is somewhat helpful.
