deep-water
Beyond the shallows
Deep-water describes things found in, suited for, or operating in the deep parts of oceans or lakes, away from shorelines: deep-water drilling, deep-water ports, deep-water fish.
A deep-water port has enough depth to accommodate large vessels.
Figuratively, in deep water means in serious trouble or difficulty.
