We have a cradle for sale, used to support a Contessa 26 for at least the previous 4 winters. I would advise a boat of this size is about the limit.
I rubbed it down and repainted it with Hammerite earlier this year. One of the supports is seized (in the right place for the Contessa...) and will either need to be left as is, replaced, or chocked up for a different boat.
It's stored in a garage in central Exeter, viewing possible by arrangement
