Two of the U.S. Navy's WWI era cargo ships had fewer than three hull islands. Each had different characteristics and is listed separately. Three had flush decks with different numbers of kingpost pairs, two were flush decked except for a short well forward, and two had two hull islands, a forecastle and a poop. One of these ships had three masts, the others had the usual two. One, built in the 1870s, was the Navy's last non-refrigerated supply ship.
This page features a table (with links to individual ships) of World War I era U.S. Navy supply ships and refrigerated cargo ships with fewer than three hull islands, plus a photograph of each ship in this group.
