Cuckoo's Nest was sold mid 90s and renamed Rapscallion. It sailed in the 98 Sydney Hobart (I was on it). Then sold to Tasmania and renamed Interum it sailed another couple of Sydney Hobarts I believe, last I heard it had been renamed Bombora and was perhaps in Victoria. Lovely boat, wicked offwind. Just so-so uphill, Would do well with a carbon rig and a tweaked keel IMHO.
Here's a couple more-
Micropay Cuckoos nest
Windward Passage 2
Castaway New Zealand/ Gatorade
