- The lowest full-length deck of early sailing ships.
15th century. From the Dutch word, overlope, meaning overlap, and then from Middle English.
The orlop deck can be a partial deck on smaller vessels and the term is still used on some modern merchant ships. The original Dutch meaning appears to come from this definition.
