The Motor Boys on the Atlantic

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!
