Having all these sources of standards is why the world of mil specs seems to be, to use the military's acronym, FUBAR (F---ed Up Beyond All Recognition). Also, most mil specs are for components rather than a complete boat-and as you know, there are a lot of components that go into a boat. For instance, ABYC has a standard for a nonmetallic fuel hose (P-4, 188.8.131.52). This same fuel hose will meet UL spec 1114 and SAE specification J1527, Class 1. Oh, brother! There is, however, no one simple specification for "boat, marine, attack."
