Is the Mooshuloo (or perhaps mushulu) still afloat? Last I heard she was a Resturant on the east coast. I know much of her hull was filled with sand. Some folks I knew were considering spending a large fortune on sailing her again. After some initial exploration, they figured that she was too far gone.
Ther might be another one or two in the Falkalands. There is a collection of rotting and rusting old square riggers there, many still float, but most are wood.
