shoals
Where boats ground
Shoals are shallow areas in a body of water where the bottom rises near the surface, creating hazards for navigation.
A ship may run aground on shoals.
The word also means a large group of fish swimming together: A shoal of herring passed beneath the boat.
Figuratively, shoals suggest hidden dangers or difficulties: the shoals of academic politics.
