The Harbors 
Several harbors are available for docking, Honolulu & Nawiliwili, Hawai'i;  New York, NY; Fort Lauderdale, Florida; Long Beach, California; Sydney, Australia; Southampton, UK and Apia, Samoa. All except Apia have high resolution graphics of the harbor and surrounding areas like Honolulu harbor shown below. The target dock is indicated by a yellow line in this case at Aloha Tower. So long as you keep your ship in the bright blue water, and do not violate the navigational buoys, you will not run aground. But if you venture slightly out of the blue or ignore the channel markers, the ship comes to an abrupt halt and damage accumulates.
