Do some research on Sailnet it has been discussed. I had a Nonsuch 30 and loved it for the kind of sailing that most people do. Less work, decent performance unless you absolutely need to point really high - I had considerable success in no spinnaker class racing with mine.
The masts are seriously tapered and the top of the mast can bend up to 4'. The bending absorbs a lot of load when gusts hit so the ride is smoother. BTW, I can tell you nothing about the Hunter version of an unstayed mast.
Finished the circumnavigation in early February in Grenada. Have to work on a book project for the next several months so the boat will be waiting for next year.
