Rough going

We've had a rocky time at sea the last 24 hours.  We've been lucky, neither of us has gotten sea sick and only have taken ginger pills to ward off distress.    The rolling has been punctuated with an occasional boom!  a loud smacking wave followed by an up and down motion.   A few crashes could be heard in the kitchen while we were at dinner, but they didn't close the kitchen, and all stationery objects seem to be groaning or creaking.
