CHANT.
WWII Standard Design Channel Tanker.
The CHANT channel tanker was designed during WWII to carry petrol and oil products for the Allied invasion of Europe in 1944, in all 43 were built, some inland in sections. Their straight line designs had no curved or twisted plates and with no sheer gave them a rather ugly appearance which resulted in them being nicknamed "Churchills Holy Answer to the Nazi Terror".
A total of 25 vessels of the dry cargo version was built, after the war many were decommissioned and sold into civilian use, some are still believed to be trading in the Mediterranean.
