Concrete Motor Boat Is Speedy

Prototype of the Newest of the Freight-Carrying Vesttls Built to Defeat the U-Boats

The stone age—ln boats, at least—has returned to Washington. Floating easily on the waters of the Potomac there is today the first real stone boat the capital has ever seen. It is the Concrete, a prototype, as its name Implies, of the newest of the freight-carrying vessels built to defeat the U-boats. ~ - This little motor boat, in its first trials there, more than proyed the boasts of its builders as to Its seaworthiness. The hull is only three-quarters of an Inch thick, but, driven by a ten-horse-power engine, the Concrete developed good speed in several trips and drew favorable comment from several officials who rode in It. . ~ -
