beast. It was just an unscalable, craggy wall.
Suddenly Tony bore down on the wheel. The Napoli swerved swiftly to one side and at the same time the engine roared as the craft leaped ahead.
Frank and Joe looked quickly around.
"What's the matter?" they asked, in alarm.
But Tony was gazing fixedly ahead. He was tense and alert. Another shift of the wheel and the Napoli swerved again.
Then the Hardy boys saw the danger.
There were rocks at the base of the cliff. One of them, black and sharp, like an ugly tooth, jutted out of the water almost immediately at the side of the boat. Only Tony's quick eye had saved them from striking against it. They had blundered into a veritable maze of reefs which extended for several yards ahead.
They held their breath.
It seemed impossible that they could run the gauntlet of those rocks without tearing the bottom out of the craft. But Tony's steermanship was marvelous. The motorboat threaded its way accurately among the jutting rocks. There was always the chance that a submerged reef might rip through the hull of the craft, but they had to take chances on that.
But luck was with them. The Napoli dodged the last ugly rock, and shot forward into open water.
