The Motor Boys on the Atlantic — Clarence Young

The Motor Boys on the Atlantic is the sixth in the series. The boys still have their motor boat, the Dartaway, and they're looking for new adventures; no problem. They decide to go fishing in the Atlantic Ocean-for whale and shark-and they manage to catch one of each. But the boys soon learn that catching a whale and a shark is like riding a lion-the problem isn't getting on! Along the way, however, they have a boat race with their arch-enemy, Noddy Nixon, and uncover a nefarious plot to change the lighthouse light such that boats and ships crash into the rocks, making easy pickings for the treasures they're carrying. Oh, the fiends!
