Nassau Class Nassau Class.  The hexagonal layout of the main turrets mainly necessitated by the machinery layout.  This was not seen completely a waste as the offside turrets were considered a reserve in battle that could be used by turning the ship around if the nearside turrets were knocked out.   The class is also unusual in having the distinctive "goose necked" crane abreast the aft funnel.

Comments:
The first German Dreadnoughts.  The main armament layout was dictated mainly by the retention of triple expansion machinery rather than using less bulky turbines.  Unlike the early British Dreadnoughts they retained a heavy anti-torpedo boat armament.  The ships were not good sea-boats and bilge keels were fitted which improved the problem.  For the wing turrets the magazines were above the shell rooms.  Crew of 40 officers and and 968 men.
