Power Catamaran Trawler Will A 12-metre Long, 2-metre Wide Power Catamaran Be Stable In Bad Conditions?

Will a 12-metre long, 2-metre wide power catamaran be stable in bad conditions? - power catamaran trawler

My plan is crazy, it's a Super-Cat Power time to build up a large dock work, everything has time for me to cruise at 12 knots, as all boats are smaller than it should not go faster than 5 knots ( that is the law, and if I would slowly in a small boat that take too long to go to work, so that the length).

My concern now: That's a heck of a long and narrow boat for the future. Will it remain stable? These are parameters that we speak of a catamaran, the duration of two sedans, and the width.
Thank you.
