Because it is often moist inside a boat and the conditions where boats are located are often humid, it is common on sailboat lifelines to see towels, rags, clothing and other things that got wet during the day or night. It dews heavily at night in the places that I've cruised so far, so towels and such have to be brought in or they get even wetter. They must also be brought in when the winds kick up, especially underway. I lost a dishrag overboard leaving the anchorage before Oriental. I guess I shouldn't complain since that's all I lost this trip.
