Blackfin (and Ondine III) were more-or-less contemporaries of Windward Passage. Blackfin and Windward Passage had a lot of what amounted to match racing rivalry on Transpac, Big Boat Series, etc. As I recall, WP won most of their meetings. WP was far and away the better looking of the two. Blackfin simply had too much freeboard and looked clunky alongside Windward Passage.
I think up until De Meuse's unfortunate death, he still owned Serena which was a gorgeous yacht -- much better looking than Blackfin but no longer capable of winning the Barn Door against the modern maxies.
