...Keels, fins and rudders require more complicated tests. With the help of companies such as Boeing and Digital, designers perform wind-tunnel experiments using special computer codes that help show lift and drag forces on the keel. Shapes of keels now vary widely, from the basic lead-filled bulb at the end of a fin to the hydrodynamic "winged" keel, a Y-shaped structure that has less underwater drag and more lift. The latest design: a tandem keel that combines the rudder and keel fin and eliminates the need for a separate rudder. Developed in shipyards with great secrecy...
...delicate "invisible" shoes (1945-47), which used pieces of clear nylon to create the top piece known as the vamp, were inspired by his observation of the taut, translucent lines of fishermen along the Arno River. The swooping heel of these shoes is also nautical, shaped like the keel of an America's Cup yacht. "The toes," he once said, "should always be free to swim...

...port. As I attempted to get to the conning tower over decks slippery with oil and water, I felt the shock of another very heavy explosion." Kenworthy gave the order to abandon ship. He barely made it over the rising starboard side as the giant battleship began to keel over, trapping more than 400 crewmen below decks...
...Procyon is self-tacking: as the wind pushes the jib sail in a new direction, its hardware slides along a track located on the deck, forward of the cockpit, without needing any special attention from captain or crew. Underneath it all is a 13,000-lb. winged keel, which can be moved by hydraulic power from a vertical down position to as much as a 25 degrees slant to either side. That and a two-ton water-ballast system greatly improve the vessel's stability...
