Our latest hull is the extremely versatile US C3 hull. In addition to their use as cargo ships, they were used as Bogue class escort carriers and tenders for destroyers, submarines, and seaplanes. 465 ships were made based on the C3 hull.
The hulls were deliberately made tall to make is easier to cut them down to the correct configuration.
The plug for the C3 was made by George M under the codename Escargo.
