A friend had a Fontaine-Pagot catamaran, and that came with a specification about the maximum sail to carry in various wind strengths. It was definitely in the manual, but I think there may also have been a notice plate with those limits fixed to the boat, either in the cockpit or just inside the bridgedeck saloon.
Makes sense since the lack of heeling makes it way more difficult to judge wind pressure than on a mono.
There is a report somewhere ( from Southampton Uni I think) about catamaran capsize risk which highlights the under bridge area as a key factor along with deep keels. The ideal cruising cat has shallow keels to allow sideways slide together with a narrow format, but that tends to make them poor performers to windward. As my old Prout cat was.
