'k, thanx!
I probably misinterpreted the reference...
In "Constitution Close Up: Minutiae for the Modeler and Artist" by Cmdr Tyrone G. Martin, U.S. Navy (retired}, he writes "1804 - Ship fitted with single wheel. [Quarter Bill, American Antiquarian Society.] Inferred from the fact that the bill provides for only two men on the wheel." And then
"Feb 1809 - Ship fitted with double wheel. [Midshipman John M. Funck Quarter Bill, USSCM.] Inferred from the fact that four men are provided for the wheel."
Maybe the ship's wheel was damaged and they had to use a single until proper repairs were made...?
