How rough of seas can a cruise ship handle?

Cruise ships are generally built to handle most waves in the ocean – they can routinely sail through 10-15 feet waves without issues. Waves up to 50 feet typically won't sink a ship, but can cause damage.

Gyroscopes, thrusters, and counterweights prevent the ship from swaying in the water. By reducing rolling and pitching, they maintain a stable experience for all passengers and crew on board the vessel, but, more importantly, they prevent the ship from tipping over, even in the roughest waters.

When the stabilizers aren't needed, they are retracted into the vessel's side. Older and smaller ships are less likely to have this technology and are much more apt to feel the motion of the ocean. A mega-ship, such as Royal Caribbean's Harmony of the Seas, might just be the best cruise ship to avoid seasickness.
