I like this boat. Saw yesterday at Shearwater (wasn't bad) and last weekend at Oatland.
Well worth a closer look if you are sailing near it. 
I've got a mate who sails a 42ft cat called "Two Up", but I thought he was still up north. Can you confirm what the 'Two Up' you are referring to is.
With thanks.....
^ Let's just say it is a party boat, popular with buck's parties.
It's a cat, but powered, so probably not your mate.
