Dead Astern
Return To Index
"Dead astern" in sailing refers to a position or direction directly behind a vessel's stern (rear), specifically at a relative bearing of 180°. It indicates an object, hazard, or wind direction aligned directly behind the centerline of the boat, opposite to "dead ahead".
Key Aspects of Dead Astern:
Location: Directly behind the boat, in line with the keel.
Usage: Used in navigation and lookout reporting to identify the precise location of objects or wind direction.
Relative Bearing: The 180° point in the relative bearing system.
Wind/Sailing: "Dead downwind" means the wind is coming from directly behind the boat (dead astern), which often requires specialized sailing techniques like wing-on-wing.
