At sea, I have ridden through some storms that made it a little hard to walk around, but sleep was not a problem. Ship motion at sea is a bit different from bus motion on a road, but not as far as whether it is predictable. Sometimes we're rolling along and then there is a sharp jolt, as if an odd wave came by. * From Emerald Princess at sea
