Malrose was the lead design illustrator for Popular Mechanics magazine, which at the time was located in Chicago. The No-Vac design and build actually began in 1933, when Malrose conceptualized an airfoil hull surface design which proved to produce far less drag than conventional "V" style boat hull designs of the time.

While paddles and sails are still used on some smaller boats, most modern ships are propelled by mechanical systems consisting of an electric motor or internal combustion engine driving a propeller, or less frequently, in pump-jets, an impeller. Marine engineering is the discipline concerned with the engineering design process of marine ...
The higher the angular momentum, the greater the resisting force of the gyro to external torque (in this case more ability to cancel boat roll). A gyroscope has three axes: a spin axis, an input axis, and an output axis. The spin axis is the axis about which the flywheel is spinning and is vertical for a boat gyro.
