Patrol boats are generally not considered “oceanic war vessels”. The US Army has never differentiated between “oceanic”, “coastal” and “river” on an operational level. If a boat was needed it sailed. I’ve sailed the old 1466 class LCUs and Mike 8s in Pacific typhoons because of operational necessity.
And yes – the crews were banged up a bit, but that was part of the fun.

After posting, I was thinking about that (i.e. Patrol Coastal). I think NSW (who owned the PC's at the time) was trying to prove their new PC's could do ocean transits without too many difficulties. I'm not sure if it was rated a success.

Next time I'll have my first cup o' joe prior to posting ;-)
