Teddy will find you after you complete the Living on the Edge to begin Rite of Passage, a quest to perform an old Far Harbor ritual, the Captain’s Dance. Head to Emmet’s Causeway and drop any fresh meat you have in your inventory in the water.
Fight the first wave of Mirelurks and drop more meat in the water to fight stronger Mirelurks and, finally, the Mirelurk Queen. Return to Teddy Wright as the victor of the Captain’s Dance to receive The Captain’s Hat, which increases the wearer’s movement by 10%, and to trigger The Changing Tide.
