Except, of course, on boats. The idea for a new design was often noodled on, or near, a cocktail napkin. If sobriety did not dampen enthusiasm, the effort then tracked along a spiral course: thousands of hours of balancing the demands of the client with those of the natural world. Hydrostatics and structural engineering were predictable, but each client’s “needs” were not. When struck with a new idea, they called night or day, often turning the design spiral into a tornado.
