After a long absence, here is a ship from the MARAD program of WW2.
The C1 M AV1 were small shallow draft vessels, which were designed for supplying the US forces in the Pacific islands. Many of these ships were sold after the war to commercial companies and were also converted to various uses, among them as drill ships foe oil exploration (Cyclone and Hurricane). Here is the basic design ship, unnamed and under the US flag
Ships which were sold commercially will be appearing later.
