Who can compare the smoothness of cruise ships on the Japan-Korea route with that on the Nile River in Egypt?

I don't know what tonnage of the cruise ship you made before, but since it is on the Nile, the tonnage should be 4k to10 K. If it is this tonnage, it can't be compared with Japanese and Korean cruise ships. The smallest cruise ship in Japan and South Korea is Henna, with a displacement of 47,000 tons, and the largest two Royal Caribbean ships have a displacement of138,000 tons. Fortunately, these Japanese and Korean cruise ships have been on, and they are all very stable. It is no exaggeration to say that they are on the ground. If the wind and waves are heavy, the balance wing at the bottom of the cruise ship will stretch out to resist the influence of the wind and waves, unless it is extreme weather such as typhoon. You can ask me questions about cruise ships directly.
