Walter, I did a search several months ago on Chinese junks and turned up boats similar to what you show here. Frankly I didn't see enough similarity, and that's what threw me off.
The one in Sausalito was for sale. Don't know if it still is. Why don't you look into that. Last I saw, it had been reduced from $60K to $40K. I really don't see how you can pass that up! With the $20K you save, you'll have the junk half paid for, bringing the total to about $20K. You could cover that by charging for rides. ;-) I'd go, though it would cost me airfare to SF.
