Like in your house, there are small cabinets in the galley where dishes, glassware (above the sink) and spices (above the refrigerator) are stored.
And like in your house, there are cabinets in the bathroom where small bottles and other containers are stored. We put the same kinds of things in there that you do in your medicine cabinet.
Now, imagine what would happen to your house if you tilted it to one side at 10 or 15 degrees, and then shook it for an hour or two.

Before we leave the dock, there is a routine list of tasks we have to undertake to get ready for sea. One of these is to make sure that the sliding door on the cabinet over the sink is closed. But on one particularly boisterous passage in the Strait of Georgia, the motion of the boat caused the sliding panel to open of its own accord, and the glassware that had been trapped inside began to escape, one after the other, like little transparent skydivers. Jane thought quickly, and subdued them by stuffing bath towels into the cabinet.
Unless you live in California, I'm guessing that you don't have to deal with this.
We had two good sails across Puget Sound this weekend... and judging by the shifting of the contents of the cabinets, they were great sails!
