Living on the Edge

Living on the Edge is a quest in the Fallout 4 add-on Far Harbor.

Detailed walkthrough
Living on the Edge is the first of two overarching Harbormen quests. It has no actual target itself, but serves as a checklist for a number of different Far Harbor side quests instead.
 * Blood Tide which consists in helping Cassie Dalton taking her revenge on the island.
 * Hull Breach which consists in helping the Mariner repairing the hull protecting Far Harbor.
 * Safe Passage which consists in helping Captain Avery restoring the fog condensers around Far Harbor.

Finishing any of these quests also marks the respective optional task of Living on the Edge as complete. Once two optional tasks are completed, Living on the Edge will be considered finished as well and Teddy Wright will ask the player character to complete the island's ancient Rite of Passage to become accepted by the locals.
