Diagram illustrating a sailboat's interaction with strong wind, showing movement and wind direction.

Planning to use springlines when docking

Like a work of fine engineering, a spring maneuver requires a design. The key is to plan the maneuver by considering the wind, current, and other obstacles, then design the placement and directions of the forces and moments.

Diagram illustrating true wind, apparent wind, and boat speed effects on sail, influencing sailing dynamics.

Sailing Wind Velocity & Direction

The faster the boat sails into the wind, the more the apparent wind speed increases and the more it feels like it is coming from the front of the boat. They say  "The apparent wind is forward of the true wind". This means the apparent wind feels like it comes from a more forward direction than the true wind.
