"But at anchor
, 5 blasts is going to get most people out asking, "what was that?". "
You must know a different class of sailors. The ones I have met have a higher tolerance for background noise
. "What was that?" "Dunno, nothing here." and they go away back to whatever they were doing before the interruption. Yeah, there's danger
all around, but it isn't incoming at you, and you don't see it or hear it, you ignore it. You don't go chasing around looking for it.
"Help! Help! Medic!" would work a whole lot better. Horn signals? That's for ships underway,doesn't mean squat on the docks to anyone I've ever met. Just gets tuned out in the background noise
