Yes, that interpretation is correct. "Canst" is an archaic form of "can" used to imply "cannot" in this context. So "Canst hear the breakers roar" would mean "Can you not hear the breakers roar?"

"Canst" is the form of the verb "can" appropriate to the second person singular. The pronoun for this used to be "thou" and all the verbs that went with "thou" ended with "-st" or "-est". So if you were talking to one person it was "thou canst" but if you were talking to a crowd it was "you can". It was the same with all the other verbs: you had, thou hadst; you did, thou didst; you wave, thou wavest; you think, thou thinkst. At some time before Shakespeare's day, the "you" forms started to be used when there was only one person, when they ought to have said "thou". By Shakespeare's day this was happening a lot, and soon after it happened most of the time, and by now it happens almost always. But you can be sure that if you see a verb with "-st" on the end in Shakespeare, there's going to be a "thou" lurking about somewhere.
