What image of the sea is presented in the different stanzas of Tennyson’s poem, ‘Break, Break, Break’?

The sea is breaking on the “cold gray stones” before the speaker. He laments that he cannot give voice to his thoughts. Yes, the fisherman’s boy shouts with his sister while they play, and the young sailor sings in his boat, but the speaker cannot express such joy. Other ships travel silently into port, their “haven under the hill,” and this observation seems to remind him of the disappearance of someone he cared for. No longer can he feel the person’s touch or hear the person’s voice. Unlike the waves, which noisily “break, break, break” on the rocks as they repeatedly come in, the “tender grace” of bygone days will never return to him.
