What does seaboard mean?
Seaboard means the coast or the coastal region of a country, island, or other geographical area. It is especially common in formal and literary contexts, as in references to the eastern or western seaboard. Unlike shoreline, which usually denotes the precise boundary between land and water, seaboard can refer to an entire coastal zone and its communities. The word is also used to identify the coast associated with a particular sea, such as the Atlantic seaboard. Its image suggests a long, continuous edge of land beside the sea, making it useful in geography, journalism, travel writing, and political or economic discussion. The expression is not usually restricted to coastal regions in tropical or temperate zones; it can describe any substantial coastline.

Where does seaboard come from?
Seaboard is a compound formed from sea and board. The word board in this sense developed from an older Germanic meaning associated with a ship's side or edge, and the compound appears in English in the early modern period. The expression was influenced by the older nautical use of board for the side of a vessel, as in overboard. The word shares its nautical and coastal associations with related forms such as aboard, seaside, and seashore.
How seaboard is actually used
The term is formal and somewhat literary in general use. It often names a broad coastal region, especially when discussing a country's coast, rather than a specific shoreline.
Easily confused with seaboard
Seaboard refers more broadly to a coastal region or the coast of a country, whereas shoreline usually means the precise line where land meets water.
Seaboard is already a term for a coast or coastal region; the phrase 'seaboard coast' is redundant.
