...There have been plenty of 90' monohulls - but no multihull (to my knowledge) has ever been built this large with closed course racing in mind.
All cats in The Race were longer than 90 ft. Afterwards Orange II, Geronimo and Banque Populaire were built larger than 90 ft.
BMW/Oracle is unique in having been built with closed course racing in mind (as you wrote) and for having the largest sail area of any multihull to date - including the 135 ft Banque Populaire.
