# Talk:CSS Maurepas

I have changed the measure of this vessel's size from displacement (which is mass) to tonnage, which does not convert to mass. The article from the Encyclopedia of Arkansas does assert that the vessel "weighed" 399 tons, which supports the displacement assertion.  But the cite from DANFS, the Naval History and Heritage Command source, states that 399 is the tonnage (the abbreviation t means tonnage; were it displacement dp would be used).  DANFS is a specialized naval source, and more authoritative on ship matters than is the Arkansas encylopedia.
It is likely that the tonnage of Maurepas is tons burthen, which is more akin to volume and has nothing to do with mass (weight).  See this source for the evolution of tonnage measurements in the United States. 
But we do not have to get into which measurement of tonnage applies; I have simply converted the "displacement" field to "tonnage".  Kablammo (talk) 15:37, 14 November 2021 (UTC)
