This portion of the Shipscribe web site contains four tables containing data on all the contracts let for construction of standard-design merchant ships during World War I by the Emergency Fleet Corporation, the shipbuilding arm of the U. S. Shipping Board. For the most part, the tables contain the same data and the main difference is the way they are sorted. The Hulls and Contracts tables, however, have some additional data on contract adjustments, and the Designs table has lines for designs that were never built. To better understand the contents of the tables see the "Key to Column Headings and Abbreviations" below. Note in particular that dates are in YYMMDD format.
