This Marine Map is fun to use. Long Beach, CA was added to the “Areas” section on the left vertical menu and was able to view Cargo Vessels, Tankers, and Tug, Pilot boats. Then, I clicked on Satellite on the top right corner and it was instantly displaying the coastline in the rich blue ocean and green land colors.
