or...
ignoring the whole crappy plot issue, and with a different paint job,
the tri in Waterworld
The cat in the Thomas crown affair was (according to the
IMDB was a D class :
The catamaran that Thomas Crown is seen racing in Long Island Sound is a D-Type Catamaran, an extremely fast and highly unstable yacht design from the 1980s. The D-Type's were designed by California based aeronautical engineers to try to break inshore multihull speed records. Today there are only a handful of them left in the world.
The Tri in Waterworld was a re-painted (old) 60 footer.
