I like both versions, though the "Sweet Brown Knowe" is less distinguished than the "Amphitrite" tune.
BTW, as a young teenager, the English poet John Masefield trained as an apprentice on the schoolship HMS Conway in the 1890s. (As a school ship, that particular Conway wasn't sailing anywhere: its permanent berth was in the Mersey.)
Masefield made only two voyages in his teens before leaving the sea. He wrote the nostalgic "Sea Fever" some years later.
