Common Mistakes
Many learners use ocean idioms too literally or place them in the wrong context. A good idiom should support the sentence, not confuse the reader.
Do not say someone is in deep water for a tiny problem. Use it for serious trouble. Do not use smooth sailing before a task begins unless you mean you expect it to be easy. Do not confuse all at sea with being physically near the sea.
Another mistake is mixing too many ocean idioms in one paragraph. For example, a sentence like I was all at sea, drowning in work, riding the wave, and sailing through the storm sounds overloaded. Choose one strong phrase and let it do the work.
