It primarily depends on the hull design and engineering plant. Fin Stabilizers can help...
Displacement also makes a difference. I have been in a lot of heavy seas some upwards of 35 ft (10 meters), never with fin stabilizers. You want to point into the seas and ride up the wave and down the wave. You don't want to ride wave top to wave top because it can hog and sag the hull. Stay out of the trough and quartering seas can also be very unpleasant. We felt the seas on the destroyers and cruisers I was on, USS Enterprise and USS Saipan, not nearly as much.
Once on USS Kidd (DDG-993) the mission required us to escort USS Canisteo, an old AO, back from the Baltic to the US in the winter. We were heading into the wind and because of her required speed (she plowed through), we were at the exact wrong speed and pitched violently for a week, cracking aluminum welds in cold weather.
See you in Chattanooga?
