A lookout or look-out is a person on a ship in charge of the observation of the sea for hazards, other ships, land, etc. Lookouts report anything they see and or hear. When reporting contacts, lookouts give information such as, bearing of the object, which way the object is headed, target angles and position angles and what the contact is. Lookouts should be thoroughly familiar with the various types of distress signals they may encounter at sea.

Lookout Records was an independent record label, initially based in Laytonville, California and later in Berkeley, focusing on punk rock. Established in 1987, the label is best known for having released the seminal album of Operation Ivy and the first two albums by platinum-selling punk artists Green Day and for having pioneered the American pop-punk sound of the 1990s.
