....and, if a sailboat, rowboat, kayak or canoe does not have an engine (including an electric trolling motor), then all it needs is a single white light for night time navigation as opposed to the standard red/green and white nav lights and it can be a candle in a candle lantern, or a battery operated small lantern with a white light that is visible from 360-degrees, more or less, around the boat!
