Our fourth day at sea since we left Vava'u, Tonga. Tomorrow we reach Aitutaki Atoll, Cook Islands and, hopefully, use a tender boat to go ashore. The waves are pretty high today and if they continue tomorrow we most likely won't be able to tender ashore in Aitutaki.
I've taken a few pictures and one video to show how rough the seas are today but not sure it really captures it. From the picture you can see how much the motion is causing waves in the midship pool.
Modern cruise ships have stabilizers which do a great job of reducing the effects of rough seas. But stabilizers only help side to side rocking, not the up/down motion of the bow. That's why in the picture above you see waves caused by the bow going up and down with the motion of the waves.
