A Low Profile vessel (LPV) intercepted by the Colombian Navy in March may represent the first sighting of a new family of nacrosubs. The camouflaged vessel combines the once-standard layout of having the payload in the bow, cockpit amidships and single internally mounted engine in the stern with the recent trend to Very Slender Vessels. VSV-narcosubs started to be seen spring 2017 and have evolved into two distinct lineages, but all have featured aft-mounted cockpits and outboard motors. The boat is 20 meters long and just two meters wide giving a fineness ratio of 10:1.
