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.

Returning a sailboat to the Slip
Time flies when you are sailing. But sadly, the moment comes when you must return and put your vessel back in its slip.

Types of Anchors
Anchor design has been the focus of much research over thousands of years, and as a result, there are

Understanding Energy and Power
Energy: The concept of energy is likened to water for the easiest understanding. A bucket of water holds a specific amount of water which is measured in a quantity of gallons or liters. It is finite; when it is all drained out, it is gone. To gain more, it must be replaced from a source.

Global Positioning System
GPS stands for global positioning system. It uses a network of satellites in orbit. Although the GPS is used as a navigation device, it is also a form of communication to the vessel.

Anchoring
Anchoring is not simply throwing a “hook” and letting out a line. However, after watching some sailors, this seems to be their theory. Successful anchoring requires a plan considering all the factors.

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.

Docking Force Alignment and Moment Balance
When you are docking, if your boat pulls on a line attached to the dock, the line pulls back on your boat. If the forces are aligned, then nothing really happens.
