I am building several new tankers for the Merchant Fleet Mod's next beta version (or the final release!). One of them is a large, American-style tanker based on the Isherwood design system. These ships were unusual-looking compared to most WWII tankers; the most notable feature was the extended poop deck/sterncastle. This was designed to increase cargo capacity by allowing for bigger stern tank sections. The Isherwood method was originally a British innovation, and was used on many small British coastal vessels. For some reason, no large British merchant vessels seem to have used this design.

To my knowledge only one of these ships was completed before America entered the war (S.S. "Virginia"). She was sunk by a U-Boat in 1942, and "Pan Pennsylvania" was lost in 1944 to U-550:

About 11 other near-sisters were constructed between 1942 and 1945. At 10,700-11,000 GRT they were among the largest tankers in the world at the time. After the war they were all sold to civilian operators based in the US and Greece, serving well into the 1970's.

They were constructed by welding together massive prefabricated sections of hull, in order to save time. Interestingly, this design seems to have shared some of the same structural issues found with T-2 Tankers and Liberty Ships. "Keo" (ex-"Bulkoil") broke in two off Nantucket in November 1969 with no survivors. "Pacocean" (ex-"Bulkoceanic") broke apart and sank in a storm off the Taiwanese coast less than three weeks later. "Amphialos" (ex-"Bulkstar") broke up and sank near Cape Cod in 1964. "Golden Drake" (ex "Bulktrader") exploded in 1972 and sank after a towing attempt failed. At least 39 crewmembers were lost in these incidents. For more details, click here:

BTW, sincere apologies to everyone for the additional delays with my mod.
