Bottle Message

The Bottle messages are a series of paper notes in Fallout 4.

Locations
Bottle message 2 is located behind The Castle only the bottom of the bottle is visible.

Bottle Message 5 is located behind Mahkra Fishpacking, South East corner, near the rowboat with the Plastic pumpkin on it. When picked up, it marks a location on the surface of the water near a Buoy East of the packing plant with a misc. objective. Diving deep below that marker is a coffin and a steamer trunk with assorted loot. Taking this loot completes the objective.

Bottle message 6 is located by the Nahant Oceanological Society (coordinates 28X, 17Y), on the tiny sand island just off the coast to its south east.
