Professional Ship Simulator is an open-world maritime sim with two large scenery areas and more than 40 harbors. Exact region dimensions still need a primary-source build check.
Confirmed world scope
The Steam listing confirms two large environments and more than 40 harbors, with authentic navigation infrastructure and open-world exploration.
Can large ships operate here?
Container ships, bulk carriers, LNG tankers, ferries, and cruise ships are part of the published class range. Large-vessel play focuses on planning, harbor access, traffic, weather, and assisted maneuvering rather than assuming every small harbor fits every class.
Dimensions under verification
Community material cites roughly 60 × 120 km for Rügen and 140 × 140 km for the Strait of Dover. We are not presenting those dimensions as official until they are verified in a primary source or public build.
