The Motor Boys on the Atlantic; or, The Mystery of the Lighthouse

Three adolescent friends take their motor launch to the Atlantic coast for a summer of boating and fast-paced adventure. Episodic chapters send them from a railroad wreck toward the shore into squalls and storms that leave them adrift, encounters with whales and sharks, and the exploration of an abandoned vessel. Rivalries and races complicate their outings, and a secret connected to a coastal cove and a lighthouse emerges, resulting in capture, escape attempts, and a final rescue that resolves the lighthouse mystery. The book blends maritime hazards, practical seamanship, and youthful daring across short, action-driven episodes.
