Depart, Depart from Solid Earth Why Sailing, Why Physics, Why Both? Origins There's Much More Downwind-The Easy Direction Speed Forces Boatspeed Wind Shadow Acceleration Examples The Speed Limit Upwind-The Hard Direction Overview Iceboats Sailboat Speeds Why Is Sailing Upwind So Complicated? Tipping, Torques, and Trouble Roll, Pitch, and Yaw Torques Centers of Mass, Buoyancy, and Effort Catamaran Iceboat Monohull Staying Upright Steering and Helm Dynamics Upright Mast Personal Torques See How the Mainsail Sets Spinnaker Mainsail and Jib Real Sails What Really Counts Fluid Dynamics Navier-Stokes Equation Viscosity Reynolds Number Boundary Layers Euler Equation Why Are Fluids So Complicated? Surfaces An Example Inadequate Theory Curiosities When Is It Smooth Enough? Waves and Wakes Wave Shape Water Motion Gravity Waves Capillary Waves Damping Wind and Waves Wave Packets and Group Velocity An Example Wakes The Importance of Waves Wind Two Examples Turbulence Wind up High Weather Apologies Strategy Directions Constant Preferred Direction Variable Preferred Direction Current Least-Time Path Light Analogy Mathematical Approach Predicting the Wind Real Sailing Finally Sailing Glossary Index
