A xebec is a small three-masted ship with both square and triangular sails.
One of my dictionaries suggests derivation from Arabic via French
chebec.
I don't know if the usage is archaic or inappropriate, but I have seen
'Oberstecher' equated to Overtaker in descriptions of an old German card
game (the name of the three of trumps in Karnõffel).
As for the Dragon and Murray Lion, I don't know if either has a customary
German name, but Hund strikes me as potentially appropriate for either
move.
I'd like to see the list when it is done. :)
