Galleys get 3 damage boxes, 2-1-1. Gunboats get 2, 1-1. How about a 45 or 60 degree forward firing arc? This is because galleys typically had 1 big gun supplemented with small guns firing forward. The gunboats can have a 2-1 if they are only carrying a carronade. Galleys have a stern arc that is -1 of the bow arc strength.
