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.
Back to Grenada in early December. Not sure I will remember how to sail. Will spend the winter and early spring in the Caribbean and then head to Bermuda and the northeast US. Still trying to decide if we will bring the boat to Canada, either in 2015 or 2016.
