The 40-knot sailboat

(Cover) Introducing the AEROHYDROFOIL, a revolutionary development in sailing craft that breaks the 5,000-year-old speed barrier (Dust Jacket) From ancient times seemingly insurmountable barriers have thwarted man's attempts to increase substantially the speed of sailboats. Now, at last, a new application of airfoils and hydrofoils, replacing the speed-limiting elements of hull, sails, and ballast, makes possible speeds never before attained by any sailing vessel. This is an exciting new concept for everyone who is fascinated by speed, the sea, and ships.
