describe the scene at the sea

Scrooge was afraid of the trip to sea. The rocks were frightening, the roar of the water overwhelming, and the water rolled below them. The spirit brought him to a lighthouse, where the two men who guarded and watched still celebrated, clasped hands, shared a cup of grog, and wished each other a Merry Christmas. The elder sang a song.

Then they moved to a ship, where the seamen worked and continued with their duties all while humming Christmas tunes, thinking Christmas thoughts, speaking quiet well wishes, and thinking of their families. They were each kinder that day, and they each in their own way celebrated the Christmas holiday.

The passage in it's entirety;

"Not to sea? To sea. To Scrooge's horror, looking back, he saw the last of the land, a frightful range of rocks, behind them; and his ears were deafened by the thundering of water, as it rolled and roared, and raged among the dreadful caverns it had worn, and fiercely tried to undermine the earth.

Built upon a dismal reef of sunken rocks, some league or so from shore, on which the waters chafed and dashed, the wild year through, there stood a solitary lighthouse. Great heaps of sea-weed clung to its base, and storm-birds -- born of the wind one might suppose, as sea-weed of the water -- rose and fell about it, like the waves they skimmed.

But even here, two men who watched the light had made a fire, that through the loophole in the thick stone wall shed out a ray of brightness on the awful sea. Joining their horny hands over the rough table at which they sat, they wished each other Merry Christmas in their can of grog; and one of them: the elder, too, with his face all damaged and scarred with hard weather, as the figure-head of an old ship might be: struck up a sturdy song that was like a Gale in itself.

Again the Ghost sped on, above the black and heaving sea -- on, on -- until, being far away, as he told Scrooge, from any shore, they lighted on a ship. They stood beside the helmsman at the wheel, the look-out in the bow, the officers who had the watch; dark, ghostly figures in their several stations; but every man among them hummed a Christmas tune, or had a Christmas thought, or spoke below his breath to his companion of some bygone Christmas Day, with homeward hopes belonging to it. And every man on board, waking or sleeping, good or bad, had had a kinder word for another on that day than on any day in the year; and had shared to some extent in its festivities; and had remembered those he cared for at a distance, and had known that they delighted to remember him.

It was a great surprise to Scrooge, while listening to the moaning of the wind, and thinking what a solemn thing it was to move on through the lonely darkness over an unknown abyss, whose depths were secrets as profound as Death."
