Yes, slower cats may roll, but they roll much less than monohulls. At rest they don't roll much at all. |
The difference between a cat and a monohull in movement is that the cat is "rolled" by different waves at the same time, making the hulls move less rythmic which is not always nice. I donīt know if there are stabilizers specially developed and used on big cats, but I have not seen it. I think the SWATH system with submerged sponsons might be a better solution to prevent this rocky movement. There are also other hulls with three or four submerged sponsons that could be good options, so there are solutions coming which we will probably first see on passenger vessels. But if the yacht buyer will go for such exotic hulls remains to be seen...
