Archibald Cary Smith (September 4, 1837 – December 8, 1911), professionally known as A. Cary Smith, was a naval architect and marine engineer. He studied marine painting for a short time and did some art work. He is known as the first American to develop the concept of designing a yacht on paper using calculations and comparisons. The method of drafting has since been followed in many educational institutions and universities for the teaching of yacht construction.
