Boat (Fallout 3)

A tugboat was a large boat used by people before the Great War.

Fallout 3
Tugboats appear frequently in the Tidal Basin, Potomac River, and some small lakes. They can also be found in the Fallout 3 add-on Point Lookout. Many have loot inside them.

Fallout: New Vegas
They only appear infrequently in Lake Mead, and never house loot. Another tugboat can be found inside the Collapsed Overpass Tunnel in Lonesome Road, there is no given reason why it was placed there.

Appearances
Tugboats appear in Fallout 3 and Fallout: New Vegas.
