Ensign Darrin followed with the best description he had of the strange yacht.

Less than a minute later the lights on both navy launches had picked up the strange yacht, well over in the Channel. Dave studied her through his glass.

"That's the craft," Darrin muttered to himself. "My, but she looks her part! While she isn't large for a freighter, she's well calculated for that class of work."

"Your best speed ahead, sir!" shouted Whyte, through a megaphone. "Board the yacht on her starboard quarter. Quick work, sir!"

"Very good, sir!" Dave called back.

Then he stepped swiftly amidships to the engineers.

"Get every inch of speed to be had out of the engines, my man."

Next, to the helmsman:

"Quartermaster, steer straight ahead and make that yacht's starboard quarter!"

As Dave turned, he found his own face within three inches of Seaman Runkle's glowing countenance.
