ShipIntel gives you the option of three different Map Styles.

Click on the Pen Button in your upper right corner of the map to get the different options on your map style. Click on either one to change your style.

Please note that if you choose the Satellite style you will not be able to add the other map layers as ECA/SECA, INL, Polar, Sea ice, Canals, EEZ, Load lines, and Anti-piracy.
