I have tryed the Virtual Sailor 7 DEMO, which is timed, and great to me, like Ship Simulator 2008. I tryed VSD(Virtual Sailor Demo)'s large ship, Baltic, I think it is Adriatic, and it is as good as SS08 to me. Besides in VS, you can set the depgh of the sea, the height of the waves, and either sink or capsize a ship. I think if the builders of Virtual Sailor 7 makes a Virtual Sailor 8, they should make their demo untimed. Besides, Ship Simulator 2008 and 2006 demos are untimed.
