some more pictures of Queimarala, a KHSD 42 world cruising catamaran.

I helped build the hulls to this boat back in the 80s. I flew around the world building people’s CM hulls back in those days, when CM was new.

If I remember correctly, they sailed her almost around the world and turned back before crossing the strings. It looks like a serious ocean boat to me.
