The boy who helps Santiago in The Old Man and the Sea is Manolin. He is a young Cuban fisherman who admires the aging Santiago and remains loyal to him even after Santiago suffers a long run of bad luck.
Manolin once fished with Santiago, but his parents eventually made him join another, more successful boat. Even so, he continues to care for Santiago, bringing him food, newspapers, and fishing equipment. He also helps prepare Santiago for another voyage and worries about his health.
Manolin represents affection, loyalty, and hope across generations. Santiago teaches him fishing and courage, while Manolin gives Santiago companionship and emotional support. Their relationship is central to the novella, which is set near Havana and follows Santiago's struggle to land a giant marlin.
A common mix-up is confusing Manolin with Santiago, the old fisherman himself, or with the marlin. Manolin is not Santiago's son; he is his apprentice and devoted friend.
