I just read that Cruising World article about the 70 foot wooden cat built a long time ago (70's?) just restored and it hit a rock at anchorage and partially sank.

It has a mizzen and broke all kinds of records in it's prime

There is also a commercial production cruising cat (maybe 40'?) with what looks like two furling jibs and no main.

Someone here posted pics of a cat with what looked like two windsurf rigs (one on each hull).
