Yes, I agree, though this icon was actually quite nice already.
Even shoreline large buildings are large plots primarily and can be use for everything else.
The information that you can also build a port there comes second.
I've left out the waves. They destroy the contour of the "big" icon and don't make things any clearer.
Changed to a lighter shade blue that looks more like blue and made the anchor slightly bigger.
