The United States Revenue Cutter Crawford was the first of the 13 cutters of the Morris-Taney Class to be launched. These cutters were the backbone of the Service for more than a decade. Samuel Humphreys designed these cutters for roles as diverse as fighting pirates, privateers, combating smugglers and operating with naval forces. He designed the vessels on a naval schooner concept. They had Baltimore Clipper lines. The vessels built by Webb and Allen, designed by Isaac Webb, resembled Humphreys' but had one less port.
