Kowan class ASR submarine rescue ship LOA 275′ TDISP 2,100 tons probable catamaran hull. This was apparently built in the 1980s in Najin. It may have elements in common with the slightly smaller Soho class above. There is a single photo online, from Morning Fog’s blog, which appears to be of this vessel, which shows a catamaran with conventional raked stems with trawler-like lines. This ship also shares some features with the retired USN Pigeon class submarine rescue catamarans.
