Question: What does neaped mean in reference to a ship?

Answer: A boat that is neaped has gone aground on a mild tide and needs a spring tide or stormy waters to float it off. The boat is only barely aground, as opposed to being hard aground, where even a very high tide or rough waters might not be enough to set it free. The expression comes from the term “neap tide,” which is a moderate tide. Neap tides occur when Earth, Moon, and Sun are in quadrature. In other words, instead of being lined up in a straight line, as at syzygy, they are more nearly at right angles. True quadrature happens at regular intervals, about twice a month, at the first quarter and last quarter Moons, but neap tides occur for several days around those dates. Take a look at the tides on the right-hand calendar pages of The Old Farmer’s Almanac, and you’ll notice that high tides are considerably higher around the full Moon and new Moon than around the first and last quarters.
