Lookouts scan the horizon, searching for any boat or vessel that looks out of place, careful eyes watch the radar screen. The entire crew is on edge; radio chatter between ships is nearly constant. Fishing vessels, normally a routine part of ocean travel, get extra scrutiny and wide passage. Any small boat approaching the ship sets off alarm bells. Anyone who makes their living on the sea knows these waters, one of the corridors of global commerce for as long man has been writing things down, are a dangerous place to travel.
