Alexander McDougall (ship)
SS Alexander McDougall was a "whaleback" ship, the last and longest whaleback ever built.[1] The design, created by Scottish captain Alexander McDougall (1845–1923), enabled her to carry a maximum amount of cargo with a minimum of draft. Whalebacks were also called "pig boats", among other names, due to their appearance. The Alexander McDougall was the only whaleback built with a traditionally shaped bow. This was done in an attempt to increase the strength of the ship's hull so that the beam could be increased.
