seondumast
Seondumast is a term used to describe a specific type of mast or spar, often encountered in nautical contexts or historical shipbuilding. While not a universally recognized technical term in modern maritime dictionaries, it appears in certain historical texts and regional dialects. The exact etymology and precise definition can vary, but generally, a "seondumast" refers to a secondary mast, distinct from the primary or mainmast of a vessel.
This secondary mast might be smaller in stature and positioned either forward or aft of the mainmast.
