I think my issue is more about fresh air than motion. We find ways to leave hatches open in a cat that we can't seem to with a monohull.

Cat stoves gimble too (is that a word?). I've always seen a gimble bolt on them.

If I were chartering (not cruising) and it was just my wife and I, or two couples with a lot of sailing experience, we'd probably get a monohull. For cruising, in the future, we plan to live on a cat, just a personal preference I guess.
