> The proportions of the yards on a British naval vessel (the wooden timber 
> from which a square or lateen sail is furled) are determined by odd 
> fractions of an inch to a yard of length.  As it happens the minimum 
> diameter of the top gallant, mizzen topsail, and spritsail topsail yards 
> is eight thirteenths of an inch to each yard of length.  Thus a yard say 
> 27 feet long, or nine yards, will be nine times eight/thirteenths of an 
> inch or about 5 1/2 inches, at the ends.  The yards of other sails are 
> vaiously measured in sevenths, nineths and other fractions of an inch, per 
> yard of length.
