I'm the proud owner of GG30 "Lurianna". Some photos can be seen at:

Some posts from me (as GGFan) in the woodenboat forum deal with this (in my eyes) marvelous design. She sails very well, even to windward, and is quite stiff, no reef necessary up to the end of a force 4. After 4 seasons I'm still very happy with Lurianna.
Jollydodger, if you need further informations or if you would like to see some pics of the building process, please send me a pm.
Kind regards, Helmuth
