whaleback
Arched ship deck
A whaleback is anything shaped like a whale's back—a rounded, humplike form.
The term applies to hills, rocks, cloud formations, and waves with this profile.
In maritime history, whalebacks were late 19th-century Great Lakes cargo ships with curved steel decks designed to shed water: The whaleback *Meteor* is the last of its kind still afloat.
